The AmazonKMS control provides an easy-to-use interface for Amazon's Key Management Service.

Syntax

AmazonKMS

Remarks

The AmazonKMS control makes it easy to work with the Amazon Key Management Service (KMS) in a secure manner using TLS. Amazon KMS allows you to create, manage, and use KMS keys for cryptographic operations. You can also work with aliases, and generate data keys and data key pairs.

To begin, register for an AWS account and obtain an AccessKey and SecretKey to use for authentication. Once one or more KMS keys have been created, either via the AWS console (recommended) or this API, you'll be ready to start using the control to manage and use the KMS keys.

Resource Terminology

As implied above, there are three kinds of resources associated with Amazon KMS. The primary resource type is the AWS KMS key, or "KMS key". KMS keys can be symmetric or asymmetric, and can be used either for encryption and decryption, or signing and verification. KMS keys themselves can never leave the Amazon cloud, they are used for server-side cryptographic operations only. This is a security feature, but it does mean that the amount of data that can be processed in a KMS key-based cryptographic operation is relatively small.

To work around the small server-side cryptographic operation data limit, Amazon KMS also supports the generation of data keys (symmetric) and data key pairs (asymmetric), which can then be used outside of Amazon KMS in order to encrypt/decrypt and sign/verify larger amounts data. KMS itself only generates these keys, it does not track them or make use of them for cryptographic operations. However, it does encrypt the data key (or, for data key pairs, the private key) using a KMS key when it is generated, which means that the key must be decrypted using a KMS key each time it needs to be used. For more information, refer to Amazon's Envelope Encryption description, which details the many security benefits of this strategy.

The last resource is called an alias. Aliases provide friendly names for KMS keys, which can otherwise only be identified by their Id or Amazon resource name (ARN). Since an alias is a standalone resource, it can be created and deleted without affecting the KMS key it refers to. It can also be updated to refer to a different KMS key at any time.

Note: KMS keys and aliases are region-specific resources. That is, KMS keys and aliases cannot be accessed or used outside of the region that they reside in.

Using the Control

KMS keys can be created using the CreateKey method. A KMS key's key spec (i.e., whether it is symmetric or asymmetric, and in the latter case, what kind of asymmetric) and usage (i.e., whether it is for encryption/decryption or signing/verification) must be set at the time of creation, and they cannot be changed later. A description of the KMS key can also be provided when it is created, and can be changed at any time using the UpdateKeyDescription method.

When a KMS key will no longer be used, it can be scheduled for deletion using the ScheduleKeyDeletion method. AWS requires that KMS keys remain in a "pending deletion" state for at least seven days to help ensure that they are truly no longer needed. If at any time during the waiting period it is discovered that the KMS key is still needed, the deletion can be canceled using the CancelKeyDeletion method (KMS keys cannot be used while they are pending deletion). // The CreateKey method returns the Amazon resource name of the newly-created KMS key. string keyArn = kms.CreateKey("SYMMETRIC_DEFAULT", false, "Test key"); // ... Some time later ... // Schedules the KMS key for deletion in 15 days. kms.ScheduleKeyDeletion(keyArn, 15);

Aliases can be created and deleted using the CreateAlias and DeleteAlias methods. Also, while aliases can be updated to refer to a different KMS key at any time during their lifetime. Note that all alias names must begin with the prefix alias/ (but cannot begin with alias/aws/, which is a reserved prefix). kms.CreateAlias("alias/MyTestKey", keyArn); kms.UpdateAlias("alias/MyTestKey", otherKeyArn); kms.DeleteAlias("alias/MyTestKey"); // Only deletes the alias; the KMS key it refers to is unaffected.

To list KMS keys or aliases, use the ListKeys and ListAliases methods. For the former, the IncludeKeyDetails property can optionally be enabled to have the control attempt to retrieve the full information for each KMS key (Amazon only returns the KMS key's ARN and Id while listing). // If there are many KMS keys to list, there may be multiple pages of results. This will // cause all pages of results to be accumulated into the Keys collection property. do { kms.ListKeys(); } while (!string.IsNullOrEmpty(kms.KeyMarker)); foreach (AWSKey key in kms.Keys) { Console.WriteLine(key.ARN); }

Depending on a KMS key's usage, it can be used to perform different cryptographic operations. KMS keys with encryption/decryption usage can be used in Encrypt, Decrypt, and ReEncrypt operations. KMS keys with sign/verify usage can be used in Sign and Verify operations. To perform a cryptographic operation, use InputData or InputFile to supply the input data that should be processed. All operations will output the result data to OutputData or OutputFile (except Verify; refer to its documentation for more information). // Create an asymmetric KMS key with encrypt/decrypt usage. string keyArn = kms.CreateKey("RSA_4096", false, "Encryption Key #237"); // Encrypt the string "Test123" and write the encrypted data to an output file. kms.InputData = "Test123"; kms.OutputFile = "C:/temp/enc.dat"; kms.Encrypt(keyArn, "RSAES_OAEP_SHA_256"); // ...Later, decrypt the data again. kms.InputFile = "C:/temp/enc.dat"; kms.OutputFile = ""; // So that the data will be output to the OutputData property. kms.Decrypt(keyArn, "RSAES_OAEP_SHA_256");

It's important to note that the amount of data that can be processed in server-side cryptographic operations is very small. For signing operations, it is limited to 4096 bytes; for encryption operations, the limit varies based on the selected KMS key's key spec and the selected encryption algorithm (see the Encrypt method's documentation for more information).

To work around this issue, Amazon KMS supports the generation of data keys and data key pairs (described above) which can be used locally to encrypt/decrypt or sign/verify large amounts of data. To generate a data key or a data key pair, call the GenerateDataKey and GenerateDataKeyPair methods. // Generates a data key, including a plaintext copy. // The encrypted copy is encrypted by the specified KMS key. kms.GenerateDataKey("AES_256", keyArn, true); // The resulting information is stored in the following properties: // kms.KeyData.ARN: The ARN of the KMS key used to encrypt the data key. // kms.KeyData.EncryptedKey: The encrypted copy of the data key. // kms.KeyData.KeySpec: The spec of the generated data key. // kms.KeyData.PlaintextKey: The plaintext copy of the data key (if it was requested). // Generates a data key pair, including plaintext copy. // The encrypted copy of the private key is encrypted by the specified KMS key. kms.GenerateDataKeyPair("ECC_NIST_P384", keyArn, true); // The resulting information is stored in the following properties: // kms.KeyData.ARN: The ARN of the KMS key used to encrypt the data key pair's private key. // kms.KeyData.EncryptedKey: The encrypted copy of the private key. // kms.KeyData.KeySpec: The spec of the generated data key pair. // kms.KeyData.PlaintextKey: The plaintext copy of the private key (if it was requested). // kms.KeyData.PublicKey: The data key pair's public key.

amazonkmscontrol.SSLProvider[=integer]

Possible Values

sslpAutomatic(0), 
sslpPlatform(1), 
sslpInternal(2)

Default Value

0

Remarks

This property specifies the SSL/TLS implementation to use. In most cases the default value of 0 (Automatic) is recommended and should not be changed. When set to 0 (Automatic) the control will select whether to use the platform implementation or the internal implementation depending on the operating system as well as the TLS version being used.

Possible values are:

0 (sslpAutomatic - default)Automatically selects the appropriate implementation.
1 (sslpPlatform) Uses the platform/system implementation.
2 (sslpInternal) Uses the internal implementation.
Additional Notes

In most cases using the default value (Automatic) is recommended. The control will select a provider depending on the current platform.

When Automatic is selected the platform implementation is used by default. When TLS 1.3 is enabled via SSLEnabledProtocols the internal implementation is used.

Data Type

Integer

SSLServerCertEncoded Property (AmazonKMS Control)

This is the certificate (PEM/base64 encoded).

Syntax

amazonkmscontrol.SSLServerCertEncoded

Default Value

""

Remarks

This is the certificate (PEM/base64 encoded). This property is used to assign a specific certificate. The SSLServerCertStore and SSLServerCertSubject properties also may be used to specify a certificate.

When SSLServerCertEncoded is set, a search is initiated in the current SSLServerCertStore for the private key of the certificate. If the key is found, SSLServerCertSubject is updated to reflect the full subject of the selected certificate; otherwise, SSLServerCertSubject is set to an empty string.

To read or write binary data to the property, a Variant (Byte Array) version is provided in .SSLServerCertEncodedB.

This property is read-only and not available at design time.

Data Type

Binary String

Timeout Property (AmazonKMS Control)

A timeout for the control.

Syntax

amazonkmscontrol.Timeout[=integer]

Default Value

60

Remarks

If the Timeout property is set to 0, all operations will run uninterrupted until successful completion or an error condition is encountered.

If Timeout is set to a positive value, the control will wait for the operation to complete before returning control.

The control will use DoEvents to enter an efficient wait loop during any potential waiting period, making sure that all system events are processed immediately as they arrive. This ensures that the host application does not "freeze" and remains responsive.

If Timeout expires, and the operation is not yet complete, the control fails with an error.

Please note that by default, all timeouts are inactivity timeouts, i.e. the timeout period is extended by Timeout seconds when any amount of data is successfully sent or received.

The default value for the Timeout property is 60 seconds.

Data Type

Integer

AddEncryptionContextItem Method (AmazonKMS Control)

AddQueryParam Method (AmazonKMS Control)

Adds a query parameter to the QueryParams properties.

Syntax

amazonkmscontrol.AddQueryParam Name, Value

Remarks

This method is used to add a query parameter to the QueryaParam* properties. Name specifies the name of the parameter, and Value specifies the value of the parameter.

All specified Values will be URL encoded by the control automatically. Consult the service documentation for details on the available parameters.

CancelKeyDeletion Method (AmazonKMS Control)

Cancels the deletion of the specified KMS key.

Syntax

amazonkmscontrol.CancelKeyDeletion KeyId

Remarks

This method cancels the deletion of the KMS key specified by KeyId. Refer to the ScheduleKeyDeletion method for more information.

The value passed for the KeyId parameter must be the Id or ARN of a KMS key in the current account and Region.

ClearKeyData Method (AmazonKMS Control)

Clears information stored in the KeyData properties.

Syntax

amazonkmscontrol.ClearKeyData PlaintextOnly

Remarks

This method clears the information stored in the KeyData* properties, removing it from memory. If the PlaintextOnly parameter is , only the KeyDataPlaintextKey property is cleared.

Config Method (AmazonKMS Control)

Sets or retrieves a configuration setting.

Syntax

amazonkmscontrol.Config ConfigurationString

Remarks

Config is a generic method available in every control. It is used to set and retrieve configuration settings for the control.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the control, access to these internal properties is provided through the Config method.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

CreateAlias Method (AmazonKMS Control)

Creates a new alias.

Syntax

amazonkmscontrol.CreateAlias Name, KeyId

Remarks

This method creates a new alias with the given Name and associates it with the KMS key specified by KeyId.

The value passed for Name must begin with alias/, and must consist solely of alphanumeric characters, forward slashes /, underscores _, and hyphens -. The final name must not begin with alias/aws/, which is a reserved prefix.

The value passed for the KeyId parameter must be the Id or ARN of a KMS key in the current account and Region.

CreateKey Method (AmazonKMS Control)

Creates a new KMS key.

Syntax

amazonkmscontrol.CreateKey KeySpec, ForSigning, Description

Remarks

This method creates a new KMS key of the specified KeySpec, and returns its Amazon resource name (ARN). The new KMS key's Id is the last part of the returned ARN; for example, if the ARN is arn:aws:kms:us-east-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab, then the KMS key's Id is 1234abcd-12ab-34cd-56ef-1234567890ab.

The KeySpec parameter specifies the type of KMS key that should be created. To create a symmetric key, pass SYMMETRIC_DEFAULT (or empty string); this will create a key using a symmetric algorithm based on AES-256-GCM. To create an asymmetric key, pass one of the following strings instead:

  • RSA_2048
  • RSA_3072
  • RSA_4096
  • ECC_NIST_P256 (secp256r1)
  • ECC_NIST_P384 (secp384r1)
  • ECC_NIST_P521 (secp521r1)
  • ECC_SECG_P256K1 (secp256k1)

The ForSigning parameter specifies whether the new KMS key should be for encryption and decryption () or signing and verification (). However, this is only applicable for RSA key specs; symmetric keys are always for encryption/decryption, and elliptic curve key specs are always for signing/verification, so this parameter is ignored if one of those specs is passed for KeySpec.

The Description parameter specifies the KMS key's description. This description can be changed at any time using the UpdateKeyDescription method.

To create the KMS key in a custom key store, set the CustomKeyStoreId configuration setting before calling this method. To set the KMS key's key policy, set the CreateKeyPolicy configuration setting before calling this method. Refer to these configuration settings for more information.

Decrypt Method (AmazonKMS Control)

Syntax

amazonkmscontrol.Decrypt KeyId, Algorithm

Remarks

This method decrypts data using the KMS key specified by KeyId and the given Algorithm. The data to decrypt is taken from the the specified InputFile or the InputData property. The decrypted data is output to the the specified OutputFile or the OutputData property.

The value passed for the KeyId parameter must be the Id or ARN of a KMS key, or the name or ARN of an alias, in the current Region. If an ARN is provided, it can be for a KMS key or alias in another account so long as the appropriate permissions are in place.

The Algorithm parameter specifies which algorithm to use to decrypt the data; it must match the algorithm used to encrypt the data previously. Possible values vary depending on the specified KMS key's key spec:

KMS key's Key Spec Valid Algorithms
SYMMETRIC_DEFAULT SYMMETRIC_DEFAULT (default if empty)
RSA_2048 RSAES_OAEP_SHA_1

RSAES_OAEP_SHA_256

RSA_3072 RSAES_OAEP_SHA_1

RSAES_OAEP_SHA_256

RSA_4096 RSAES_OAEP_SHA_1

RSAES_OAEP_SHA_256

If Algorithm is SYMMETRIC_DEFAULT, the encryption context items in the EncryptionContext* properties will be included in the request. Keep in mind that in order to successfully decrypt the data, the exact same encryption context items that were present when the data was encrypted must be supplied again. Encryption context items are case-sensitive, but not order-sensitive.

This method will fail if any of the following are true regarding the specified KMS key:

  • Its KeyState is anything other than aksEnabled (0).
  • It is for signing/verification instead of encryption/decryption (see KeyForSigning).
  • It is an AWS-managed KMS key (see KeyAWSManaged).

DeleteAlias Method (AmazonKMS Control)

When DoEvents is called, the control processes any available events. If no events are available, it waits for a preset period of time, and then returns.

Encrypt Method (AmazonKMS Control)

Encrypts data using a KMS key.

Syntax

amazonkmscontrol.Encrypt KeyId, Algorithm

Remarks

This method encrypts data using the KMS key specified by KeyId and the given Algorithm. The data to encrypt is taken from the the specified InputFile or the InputData property. The encrypted data is output to the the specified OutputFile or the OutputData property.

The value passed for the KeyId parameter must be the Id or ARN of a KMS key, or the name or ARN of an alias, in the current Region. If an ARN is provided, it can be for a KMS key or alias in another account so long as the appropriate permissions are in place.

The Algorithm parameter specifies which algorithm to use to encrypt the data. Possible values vary depending on the specified KMS key's key spec. The KMS key's key spec and the selected algorithm together dictate the maximum size of the input data.

KMS key's Key Spec Valid Algorithms Max Bytes
SYMMETRIC_DEFAULT SYMMETRIC_DEFAULT (default if empty) 4096
RSA_2048 RSAES_OAEP_SHA_1

RSAES_OAEP_SHA_256

446

Note that it is important to keep track of the encryption algorithm used, since it must be specified again when calling Decrypt (or ReEncrypt) later.

If Algorithm is SYMMETRIC_DEFAULT, the encryption context items in the EncryptionContext* properties will be included in the request. Including an encryption context when encrypting data means that the exact same encryption context must be supplied again in order to decrypt the data. Encryption context items are case-sensitive, but not order-sensitive.

This method will fail if any of the following are true regarding the specified KMS key:

  • Its KeyState is anything other than aksEnabled (0).
  • It is for signing/verification instead of encryption/decryption (see KeyForSigning).
  • It is an AWS-managed KMS key (see KeyAWSManaged).

  • ECC_NIST_P521 (secp521r1)
  • ECC_SECG_P256K1 (secp256k1)

The value passed for the KeyId parameter must be the Id or ARN of a KMS key, or the name or ARN of an alias, in the current Region. If an ARN is provided, it can be for a KMS key or alias in another account so long as the appropriate permissions are in place. The specified KMS key must be symmetric. Any encryption context items present in the EncryptionContext* properties will be included in the request and used when encrypting the private key; they must be supplied again in order to decrypt it.

The IncludePlaintext parameter specifies whether the server should return a plaintext (i.e., unencrypted) copy of the data key pair's private key in addition to the encrypted copy. This can be useful if the private key will be used immediately.

This method will fail if any of the following are true regarding the specified KMS key:

GenerateRandomBytes Method (AmazonKMS Control)

Generates a cryptographically-secure random byte string.

Syntax

amazonkmscontrol.GenerateRandomBytes NumBytes

Remarks

The value passed for the KeyId parameter must be the Id or ARN of a KMS key, or the name or ARN of an alias, in the current Region. If an ARN is provided, it can be for a KMS key or alias in another account so long as the appropriate permissions are in place.

GetKeyRotationStatus Method (AmazonKMS Control)

Retrieves the key rotation status for a KMS key.

Syntax

amazonkmscontrol.GetKeyRotationStatus KeyId

Remarks

This method retrieves the key rotation status for the KMS key specified by KeyId; it will return if the KMS key's key material is set to be automatically rotated, or if not.

The value passed for the KeyId parameter must be the Id or ARN of a KMS key in the current Region. If an ARN is provided, it can be for a KMS key in another account so long as the appropriate permissions are in place.

This method will always return for asymmetric KMS keys, KMS keys with imported key material, and KMS keys that reside in a custom key store, as such KMS keys do not support automatic key rotation. This method will also return if the server returns an error for any other reason.

GetPublicKey Method (AmazonKMS Control)

Retrieves the public key of an asymmetric KMS key.

Syntax

amazonkmscontrol.GetPublicKey KeyId

Remarks

This method retrieves the public key of the asymmetric KMS key specified by KeyId. The public key and its related information will be downloaded to the following KeyData* properties, refer to their documentation for more information:

ListAliases Method (AmazonKMS Control)

Lists aliases in the current account and region.

Syntax

amazonkmscontrol.ListAliases ForKeyId

Remarks

This method lists the aliases in the current account and Region. Optionally, aliases for a specific KMS key (in the current account and Region) can be listed by passing its Id or ARN for the ForKeyId parameter.

Calling this method will fire the AliasList event once for each alias, and will also populate the Alias* properties.

If there are still more aliases available to list when this method returns, the AliasMarker property will be populated. Continue to call this method until AliasMarker is empty to accumulate all pages of results in the Alias* properties.

The MaxAliases configuration setting can be used to control the maximum number of results to return at once.

ListKeys Method (AmazonKMS Control)

Lists KMS keys in the current account and region.

Syntax

amazonkmscontrol.ListKeys 

Remarks

This method lists the KMS keys in the current account and Region.

Calling this method will fire the KeyList event once for each KMS key, and will also populate the Key* properties. However, note that by default only the KeyARN and KeyId properties will be populated, since the server does not return full information for KMS keys when listing them. The IncludeKeyDetails property can be enabled to have the control attempt to retrieve full information for each KMS key; refer to its documentation for more information.

If there are still more KMS keys available to list when this method returns, the KeyMarker property will be populated. Continue to call this method until KeyMarker is empty to accumulate all pages of results in the Key* properties.

The MaxKeys configuration setting can be used to control the maximum number of results to return at once.

ReEncrypt Method (AmazonKMS Control)

Decrypts data using one KMS key and re-encrypts it using another KMS key.

Syntax

amazonkmscontrol.ReEncrypt OldKeyId, OldAlgorithm, NewKeyId, NewAlgorithm

Remarks

This method decrypts data using the KMS key specified by OldKeyId and re-encrypts it using the KMS key specified by NewKeyId. This process happens completely on the server; at no point is the unencrypted data transferred over the wire.

The encrypted data is taken from the the specified InputFile or the InputData property. The re-encrypted data is output to the the specified OutputFile or the OutputData property.

The values passed for the OldKeyId and NewKeyId parameters must be the Id or ARN of a KMS key, or the name or ARN of an alias, in the current Region. For either or both parameters, if an ARN is provided, it can be for a KMS key or alias in another account so long as the appropriate permissions are in place.

The OldAlgorithm and NewAlgorithm parameters specify the encryption algorithm currently in use, and the new encryption algorithm, respectively. Valid values vary depending on the old and new KMS keys key specs:

KMS key's Key Spec Valid Algorithms
SYMMETRIC_DEFAULT SYMMETRIC_DEFAULT (default if empty)
RSA_2048 RSAES_OAEP_SHA_1

RSAES_OAEP_SHA_256

RSA_3072 RSAES_OAEP_SHA_1

RSAES_OAEP_SHA_256

RSA_4096 RSAES_OAEP_SHA_1

RSAES_OAEP_SHA_256

Note that it is important to keep track of the new encryption algorithm used, since it must be specified again when calling Decrypt (or ReEncrypt) later.

If OldAlgorithm is SYMMETRIC_DEFAULT, the encryption context items in the EncryptionContext* properties will be included in the request for use with decryption. Keep in mind that in order to successfully decrypt the data, the exact same encryption context items that were present when the data was encrypted must be supplied again. Encryption context items are case-sensitive, but not order-sensitive.

If NewAlgorithm is SYMMETRIC_DEFAULT, the encryption context items in the EncryptionContext* properties will also be included in the request for use with re-encryption, effectively causing the encryption context to be transferred to the re-encrypted data. Alternatively, the NewEncryptionContext configuration setting can be set before calling this method in order to supply a new encryption context (or, if set to {}, to "remove" the existing one).

This method will fail if any of the following are true regarding either of the specified KMS keys:

  • Its KeyState is anything other than aksEnabled (0).
  • It is for signing/verification instead of encryption/decryption (see KeyForSigning).
  • It is an AWS-managed KMS key (see KeyAWSManaged).

Resets the control to its initial state.

Syntax

amazonkmscontrol.Reset 

Remarks

This method resets the control to its initial state.

ScheduleKeyDeletion Method (AmazonKMS Control)

Schedules the deletion of a KMS key.

Syntax

amazonkmscontrol.ScheduleKeyDeletion KeyId, DaysToWait

Remarks

This method schedules the deletion of the KMS key specified by KeyId. The DaysToWait parameter specifies the length of the waiting period; it must be a value between 7 and 30.

When a KMS key is scheduled for deletion, it cannot be used. This is a safety feature designed to help identify any code that still relies on the KMS key.

SendCustomRequest Method (AmazonKMS Control)

Sends a custom request to the server.

Syntax

amazonkmscontrol.SendCustomRequest Action

Remarks

This method can be used to send arbitrary requests to the server. The value passed for the Action parameter must be one of the actions described in the Amazon KMS documentation.

When this method is called, the control does the following:

  1. Builds a request URL, including query parameters, based on the following:
  2. Adds request headers from OtherHeaders.
  3. Adds any request body supplied via the specified InputFile or InputData.
  4. Signs the request.
  5. Sends the request to the server.
  6. Stores the response headers in the ParsedHeader* properties; and the response body in the specified OutputFile or OutputData.

If the response body is JSON data, the XPath, XText, and other X* configuration settings can then be used to navigate and extract information from it.

SetKeyEnabled Method (AmazonKMS Control)

Enables or disables a KMS key.

Syntax

amazonkmscontrol.SetKeyEnabled KeyId, Enabled

Remarks

This method enables or disables the KMS key specified by KeyId.

  • ECDSA_SHA_384
  • ECDSA_SHA_512

The IsDigest parameter specifies whether the message data is the original message () or a message digest (). When supplying a message digest, keep in mind that the same digest will need to be provided in order to Verify the signature later.

Note that a maximum of 4096 bytes of message data can be sent to the server. If IsDigest is , and more than 4096 bytes of message data are provided, the control will automatically compute an appropriate message digest and send it instead. In such cases, the computed digest is made available via the MessageDigest configuration setting.

This method will fail if any of the following are true regarding the specified KMS key:

UpdateAlias Method (AmazonKMS Control)

Updates an alias to refer to a different KMS key.

Syntax

amazonkmscontrol.UpdateAlias AliasName, NewKeyId

Remarks

This method updates the alias named AliasName, changing it so that it refers to the KMS key specified by NewKeyId.

The value passed for the AliasName parameter must include the alias/ prefix, and must be the name of an alias in the current account and Region

The value passed for the NewKeyId parameter must be the Id or ARN of a KMS key in the current account and Region. The specified KMS key must be of the same type (i.e., symmetric or asymmetric) and have the same usage (i.e., encryption/decryption or signing/verification) as the KMS key that the alias currently refers to.

This method will fail if the specified alias is AWS-managed (i.e., its name begins with alias/aws/). This method will also fail if the specified KMS key's state is aksPendingDeletion (2), or if it is AWS-managed (see KeyAWSManaged).

  • RSASSA_PKCS1_V1_5_SHA_512
  • ECDSA_SHA_256
  • ECDSA_SHA_384
  • ECDSA_SHA_512

The IsDigest parameter specifies whether the data whose signature is being verified is the original message () or a message digest (). When a message digest is supplied, keep in mind that it must be the exact same digest that was used at signing time, regardless of whether it has been recomputed.

Note that, as with the Sign method, a maximum of 4096 bytes of message data can be sent to the server. If IsDigest is , and more than 4096 bytes of message data are provided, the control will automatically compute an appropriate message digest and send it instead. In such cases, the computed digest is made available via the MessageDigest configuration setting.

This method will fail if any of the following are true regarding the specified KMS key:

SSLServerAuthentication Event (AmazonKMS Control)

Fired after the server presents its certificate to the client.

Syntax

Sub amazonkmscontrol_SSLServerAuthentication(CertEncoded As String, CertSubject As String, CertIssuer As String, Status As String, Accept As Boolean)

Remarks

This event is where the client can decide whether to continue with the connection process or not. The Accept parameter is a recommendation on whether to continue or close the connection. This is just a suggestion: application software must use its own logic to determine whether to continue or not.

When Accept is False, Status shows why the verification failed (otherwise, Status contains the string "OK"). If it is decided to continue, you can override and accept the certificate by setting the Accept parameter to True.

SSLStatus Event (AmazonKMS Control)

Shows the progress of the secure connection.

Syntax

Sub amazonkmscontrol_SSLStatus(Message As String)

Remarks

The event is fired for informational and logging purposes only. Used to track the progress of the connection.

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

The PercentDone parameter shows the progress of the transfer in the corresponding direction. If PercentDone can not be calculated the value will be -1.

Note: Events are not re-entrant. Performing time-consuming operations within this event will prevent it from firing again in a timely manner and may affect overall performance.

Config Settings (AmazonKMS Control)

The control accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the control, access to these internal properties is provided through the Config method.

AmazonKMS Config Settings

AccumulatePages:   Whether the control should accumulate subsequent pages of results when listing them.

This setting controls how the control behaves when listing multiple pages of results. If this setting is enabled, each successive page of results will be appended to the appropriate collection properties until the last page of results has been listed (at which point the next list call will cause said collection to be cleared first). If this setting is disabled, the collection will be cleared every time a page of results is returned.

By default, this setting is enabled, allowing all pages of results to be accumulated in the appropriate collection properties.

AWSProfile:   The name of the AWS CLI profile that the control should use to obtain authentication and region information.

This setting, if non-empty, must contain the name of the AWS CLI profile whose authentication and (optionally) region information the control should use to communicate with the server. To use the default profile, set this setting to default. Refer to the following pages of the AWS CLI documentation for more information about AWS profiles, and the credentials and config files used to store them:

The control supports key-based credential profiles; i.e., those which include the aws_access_key_id, aws_secret_access_key, and (optionally) aws_session_token elements. Role-based profiles are not supported at this time.

In addition to the authentication-related elements mentioned above, the control also supports the region element, if it is present in the specified profile.

The control searches for the specified profile's information in the credentials and config files. The AWSProfileDir setting can be used to configure the directory where the control looks for these files. If the aforementioned files do not exist, or the specified profile cannot be found or is missing information, an error will occur.

AWSProfileDir:   The location of the AWS CLI credentials and config files.

This setting specifies the directory that the control should check when attempting to locate the AWS CLI credentials and config files. This setting is only used if the AWSProfile setting is non-empty.

By default, this setting is empty, which will cause the control to check the default location used by the AWS CLI: an .aws directory in the current user's home directory; i.e., %UserProfile%\.aws (Windows) or ~/.aws (Linux/macOS).

CreateKeyPolicy:   The key policy JSON to send when creating a new KMS key.

This setting can be set to a fully-formed key policy JSON object before calling CreateKey in order to specify the key policy of the new KMS key.

Note that this setting's value, if non-empty, is included in the request as-is without any validation; it must be a valid key policy JSON object structured according the Amazon KMS documentation.

CustomKeyStoreId:   The Id of the custom key store that the KMS key should be created in.

This setting can be set to the Id of a custom key store before calling CreateKey in order to have the KMS key be created in that custom key store. Refer to the Amazon KMS documentation for more information.

MaxAliases:   The maximum number of results to return when listing aliases.

This setting specifies the maximum number of results that should be returned by a call to ListAliases.

If this setting is -1 (default), the server's default (50) is used. Acceptable values are 1 to 100 (inclusive).

MaxKeys:   The maximum number of results to return when listing KMS keys.

This setting specifies the maximum number of results that should be returned by a call to ListKeys.

If this setting is -1 (default), the server's default (100) is used. Acceptable values are 1 to 1000 (inclusive).

MessageDigest:   The message digest computed by the control during the last sign or verify operation, if any.

This setting can be queried after calling Sign or Verify to obtain the (hex-encoded) message digest computed by the control during the call. If the control did not generate a message digest as part of the call, an empty string will be returned.

NewEncryptionContext:   The new encryption context to use when re-encrypting data.

This setting can be set to a JSON object with string properties before calling ReEncrypt in order to have the server change the encryption context when re-encrypting (assuming SYMMETRIC_DEFAULT is passed for the NewAlgorithm parameter; other encryption algorithms do not support encryption contexts).

If this setting is empty when ReEncrypt is called, the existing encryption context specified by the EncryptionContext* properties is maintained (if possible). To explicitly remove the existing encryption context, set this setting to {}.

Note that this setting's value, if non-empty and not {}, is included in the request as-is without any validation; it must be a valid JSON object with only string-typed properties.

RawRequest:   Returns the data that was sent to the server.

This setting may be queried after calling any method that sends data to the server to obtain the request data that was transmitted. Such data may be useful for troubleshooting purposes.

RawResponse:   Returns the data that was received from the server.

This setting may be queried after calling any method that sends data to the server to obtain the response data that was received. Such data may be useful for troubleshooting purposes.

SessionToken:   The session token to send in the request when using temporary credentials.

When using temporary credentials, AWS requires you to send the session token provided with the temporary access and secret key in every request.

UseEC2RoleCredentials:   Whether to authenticate requests with credentials obtained from the IAM role attached to the EC2 instance.

When the control is running within an Amazon EC2 instance, this setting can be set to authenticate requests using the IAM role attached to the instance using temporary credentials obtained from the instance metadata service. The IMDSv2 protocol is used by default. Please see the IMDSVersion configuration setting for more information.

In order for the control to be able to auto-obtain authentication credentials, the EC2 instance must have an "instance profile" with an appropriate IAM role attached to it. Refer to the "Using an IAM Role to Grant Permissions to Applications Running on Amazon EC2 Instances" page in the Amazon IAM documentation for more information.

By default, this setting is . When set to the control will do the following before each request:

  1. Make a request against the EC2 instance to get the name of the role attached to it.
  2. Make a request against the metadata service to initiate a session. The request returns a token that must be included in subsequent requests.
  3. Parse the response, automatically populating the AccessKey and SecretKey properties and the SessionToken configuration setting.
  4. Execute the original request using the temporary security credentials that were acquired.

Note: This setting is ignored if the AWSProfile setting is set to a profile that includes credential information.

UseFIPSEndpoint:   Whether to use the FIPs endpoint to communicate with the server.

This setting specifies whether the control should use the FIPS endpoint for the currently-selected Region when communicating with the server.

By default, this setting is disabled, and the normal (non-FIPS) endpoint is used.

XChildCount:   The number of child elements of the current element.

The number of child attributes of the current element. The XChild configuration settings will be indexed from 0 to (XChildCount - 1).

The current element is specified via the XPath configuration setting. This configuration setting is read-only.

XChildName[i]:   The name of the child element.

Provides the name of the i'th child element of the current element.

The current element is specified via the XPath configuration setting. This configuration setting is read-only.

XChildXText[i]:   The inner text of the child element.

Provides the inner text of the i'th child element of the current element.

The current element is specified via the XPath configuration setting. This configuration setting is read-only.

XElement:   The name of the current element.

Provides the name of the current element.

The current element is specified via the XPath configuration setting. This configuration setting is read-only.

XParent:   The parent of the current element.

Provides the parent of the current element.

The current element is specified via the XPath configuration setting. This configuration setting is read-only.

XPath:   Provides a way to point to a specific element in the returned XML or JSON response.

The XPath setting allows you to point to specific elements in the XML or JSON response.

When XPath is set to a valid path, XElement points to the name of the element, with XText, XParent, XSubTree, XChildCount, XChildName[i], and XChildXText[i] providing other properties of the element.

XPath Syntax

XPath syntax is available for both XML and JSON documents. An XPath is a series of one or more element accessors separated by the / character, for example: /A/B/C/D. An XPath can be absolute (i.e., it starts with /), or it can be relative to the current XPath location.

The following are possible values for an element accessor, which operates relative to the current location specified by the XPath accessors which proceed it in the overall XPath string:

Accessor Description
name The first element with a particular name. Can be *.
[i] The i-th element.
name[i] The i-th element with a particular name.
[last()] The last element.
[last()-i] The element i before the last element.
name[@attrname="attrvalue"]The first element with a particular name that contains the specified attribute-value pair.

Supports single and double quotes. (XML Only)

. The current element.
.. The parent element.
Note: XPath indices are 1-based.

XPath Examples

Assuming the following XML response:

<firstlevel>
  <one>value</one>
  <two>
    <item>first</item>
    <item>second</item>
  </two>
  <three>value three</three>
</firstlevel>

Or, alternatively, the following JSON response:

{
  "firstlevel": {
    "one": "value",
    "two": ["first", "second"],
    "three": "value three"
  }
}

Here are some examples of valid XPaths:

DescriptionXML XPath JSON XPath
Document root / /json
Specific element /firstlevel/one /json/firstlevel/one
i-th child /firstlevel/two/item[2]/json/firstlevel/two/[2]

This is not an exhaustive list by any means, but should provide a general idea of the possibilities.

XSubTree:   A snapshot of the current element in the document.

Provides the entirety of the current element (including its sub-elements).

The current element is specified via the XPath configuration setting. This configuration setting is read-only.

XText:   The text of the current element.

Provides the inner text of the current element.

The current element is specified in the XPath configuration setting. This configuration setting is read-only.

HTTP Config Settings

AcceptEncoding:   Used to tell the server which types of content encodings the client supports.

When AllowHTTPCompression is True, the control adds an Accept-Encoding header to the request being sent to the server. By default, this header's value is "gzip, deflate". This configuration setting allows you to change the value of the Accept-Encoding header. Note: The control only supports gzip and deflate decompression algorithms.

AllowHTTPCompression:   This property enables HTTP compression for receiving data.

This configuration setting enables HTTP compression for receiving data. When set to True (default), the control will accept compressed data. It then will uncompress the data it has received. The control will handle data compressed by both gzip and deflate compression algorithms.

When True, the control adds an Accept-Encoding header to the outgoing request. The value for this header can be controlled by the AcceptEncoding configuration setting. The default value for this header is "gzip, deflate".

The default value is True.

AllowHTTPFallback:   Whether HTTP/2 connections are permitted to fallback to HTTP/1.1.

This configuration setting controls whether HTTP/2 connections are permitted to fall back to HTTP/1.1 when the server does not support HTTP/2. This setting is applicable only when HTTPVersion is set to "2.0".

If set to True (default), the control will automatically use HTTP/1.1 if the server does not support HTTP/2. If set to False, the control fails with an error if the server does not support HTTP/2.

The default value is True.

Append:   Whether to append data to LocalFile.

This configuration setting determines whether data will be appended when writing to LocalFile. When set to True, downloaded data will be appended to LocalFile. This may be used in conjunction with Range to resume a failed download. This is applicable only when LocalFile is set. The default value is False.

Authorization:   The Authorization string to be sent to the server.

If the Authorization property contains a nonempty string, an Authorization HTTP request header is added to the request. This header conveys Authorization information to the server.

This property is provided so that the HTTP control can be extended with other security schemes in addition to the authorization schemes already implemented by the control.

The AuthScheme property defines the authentication scheme used. In the case of HTTP Basic Authentication (default), every time User and Password are set, they are Base64 encoded, and the result is put in the Authorization property in the form "Basic [encoded-user-password]".

BytesTransferred:   Contains the number of bytes transferred in the response data.

This configuration setting returns the raw number of bytes from the HTTP response data, before the component processes the data, whether it is chunked or compressed. This returns the same value as the Transfer event, by BytesTransferred.

ChunkSize:   Specifies the chunk size in bytes when using chunked encoding.

This is applicable only when UseChunkedEncoding is True. This setting specifies the chunk size in bytes to be used when posting data. The default value is 16384.

CompressHTTPRequest:   Set to true to compress the body of a PUT or POST request.

If set to True, the body of a PUT or POST request will be compressed into gzip format before sending the request. The "Content-Encoding" header is also added to the outgoing request.

The default value is False.

EncodeURL:   If set to True the URL will be encoded by the control.

If set to True, the URL passed to the control will be URL encoded. The default value is False.

FollowRedirects:   Determines what happens when the server issues a redirect.

This option determines what happens when the server issues a redirect. Normally, the control returns an error if the server responds with an "Object Moved" message. If this property is set to 1 (always), the new URL for the object is retrieved automatically every time.

If this property is set to 2 (Same Scheme), the new URL is retrieved automatically only if the URL Scheme is the same; otherwise, the control fails with an error.

Note: Following the HTTP specification, unless this option is set to 1 (Always), automatic redirects will be performed only for GET or HEAD requests. Other methods potentially could change the conditions of the initial request and create security vulnerabilities.

Furthermore, if either the new URL server or port are different from the existing one, User and Password are also reset to empty, unless this property is set to 1 (Always), in which case the same credentials are used to connect to the new server.

A Redirect event is fired for every URL the product is redirected to. In the case of automatic redirections, the Redirect event is a good place to set properties related to the new connection (e.g., new authentication parameters).

The default value is 0 (Never). In this case, redirects are never followed, and the control fails with an error instead.

Following are the valid options:

  • 0 - Never
  • 1 - Always
  • 2 - Same Scheme

GetOn302Redirect:   If set to True the control will perform a GET on the new location.

The default value is False. If set to True, the control will perform a GET on the new location. Otherwise, it will use the same HTTP method again.

HTTP2HeadersWithoutIndexing:   HTTP2 headers that should not update the dynamic header table with incremental indexing.

HTTP/2 servers maintain a dynamic table of headers and values seen over the course of a connection. Typically, these headers are inserted into the table through incremental indexing (also known as HPACK, defined in RFC 7541). To tell the component not to use incremental indexing for certain headers, and thus not update the dynamic table, set this configuration option to a comma-delimited list of the header names.

HTTPVersion:   The version of HTTP used by the control.

This property specifies the HTTP version used by the control. Possible values are as follows:

  • "1.0"
  • "1.1" (default)
  • "2.0"
  • "3.0"

When using HTTP/2 ("2.0"), additional restrictions apply. Please see the following notes for details.

HTTP/2 Notes

When using HTTP/2, a secure Secure Sockets Layer/Transport Layer Security (TLS/SSL) connection is required. Attempting to use a plaintext URL with HTTP/2 will result in an error.

If the server does not support HTTP/2, the control will automatically use HTTP/1.1 instead. This is done to provide compatibility without the need for any additional settings. To see which version was used, check NegotiatedHTTPVersion after calling a method. The AllowHTTPFallback setting controls whether this behavior is allowed (default) or disallowed.

HTTP/3 Notes

HTTP/3 is supported only in .NET and Java.

When using HTTP/3, a secure (TLS/SSL) connection is required. Attempting to use a plaintext URL with HTTP/3 will result in an error.

IfModifiedSince:   A date determining the maximum age of the desired document.

If this setting contains a nonempty string, an If-Modified-Since HTTP header is added to the request. The value of this header is used to make the HTTP request conditional: if the requested documented has not been modified since the time specified in the field, a copy of the document will not be returned from the server; instead, a 304 (not modified) response will be returned by the server and the component throws an exception

The format of the date value for IfModifiedSince is detailed in the HTTP specs. For example: Sat, 29 Oct 2017 19:43:31 GMT.

KeepAlive:   Determines whether the HTTP connection is closed after completion of the request.

If , the component will not send the Connection: Close header. The absence of the Connection header indicates to the server that HTTP persistent connections should be used if supported. Note: Not all servers support persistent connections. If , the connection will be closed immediately after the server response is received.

The default value for KeepAlive is .

KerberosSPN:   The Service Principal Name for the Kerberos Domain Controller.

If the Service Principal Name on the Kerberos Domain Controller is not the same as the URL that you are authenticating to, the Service Principal Name should be set here.

LogLevel:   The level of detail that is logged.

This configuration setting controls the level of detail that is logged through the Log event. Possible values are as follows:

0 (None) No events are logged.
1 (Info - default) Informational events are logged.
2 (Verbose) Detailed data are logged.
3 (Debug) Debug data are logged.

The value 1 (Info) logs basic information, including the URL, HTTP version, and status details.

The value 2 (Verbose) logs additional information about the request and response.

The value 3 (Debug) logs the headers and body for both the request and response, as well as additional debug information (if any).

MaxRedirectAttempts:   Limits the number of redirects that are followed in a request.

When FollowRedirects is set to any value other than frNever, the control will follow redirects until this maximum number of redirect attempts are made. The default value is 20.

NegotiatedHTTPVersion:   The negotiated HTTP version.

This configuration setting may be queried after the request is complete to indicate the HTTP version used. When HTTPVersion is set to "2.0" (if the server does not support "2.0"), then the control will fall back to using "1.1" automatically. This setting will indicate which version was used.

OtherHeaders:   Other headers as determined by the user (optional).

This configuration setting can be set to a string of headers to be appended to the HTTP request headers.

The headers must follow the format "header: value" as described in the HTTP specifications. Header lines should be separated by CRLF (Chr$(13) & Chr$(10)) .

Use this configuration setting with caution. If this configuration setting contains invalid headers, HTTP requests may fail.

This configuration setting is useful for extending the functionality of the control beyond what is provided.

ProxyAuthorization:   The authorization string to be sent to the proxy server.

This is similar to the Authorization configuration setting, but is used for proxy authorization. If this configuration setting contains a nonempty string, a Proxy-Authorization HTTP request header is added to the request. This header conveys proxy Authorization information to the server. If ProxyUser and ProxyPassword are specified, this value is calculated using the algorithm specified by ProxyAuthScheme.

ProxyAuthScheme:   The authorization scheme to be used for the proxy.

This configuration setting is provided for use by controls that do not directly expose Proxy properties.

ProxyPassword:   A password if authentication is to be used for the proxy.

This configuration setting is provided for use by controls that do not directly expose Proxy properties.

ProxyPort:   Port for the proxy server (default 80).

This configuration setting is provided for use by controls that do not directly expose Proxy properties.

ProxyServer:   Name or IP address of a proxy server (optional).

This configuration setting is provided for use by controls that do not directly expose Proxy properties.

ProxyUser:   A user name if authentication is to be used for the proxy.

This configuration setting is provided for use by controls that do not directly expose Proxy properties.

SentHeaders:   The full set of headers as sent by the client.

This configuration setting returns the complete set of raw headers as sent by the client.

StatusCode:   The status code of the last response from the server.

This configuration setting contains the result code of the last response from the server.

StatusLine:   The first line of the last response from the server.

This setting contains the first line of the last response from the server. The format of the line will be [HTTP version] [Result Code] [Description].

TransferredData:   The contents of the last response from the server.

This configuration setting contains the contents of the last response from the server.

TransferredDataLimit:   The maximum number of incoming bytes to be stored by the control.

If TransferredDataLimit is set to 0 (default), no limits are imposed. Otherwise, this reflects the maximum number of incoming bytes that can be stored by the control.

TransferredHeaders:   The full set of headers as received from the server.

This configuration setting returns the complete set of raw headers as received from the server.

TransferredRequest:   The full request as sent by the client.

This configuration setting returns the full request as sent by the client. For performance reasons, the request is not normally saved. Set this configuration setting to ON before making a request to enable it. Following are examples of this request:

.NET Http http = new Http(); http.Config("TransferredRequest=on"); http.PostData = "body"; http.Post("http://someserver.com"); Console.WriteLine(http.Config("TransferredRequest")); C++ HTTP http; http.Config("TransferredRequest=on"); http.SetPostData("body", 5); http.Post("http://someserver.com"); printf("%s\r\n", http.Config("TransferredRequest"));

UseChunkedEncoding:   Enables or Disables HTTP chunked encoding for transfers.

If UseChunkedEncoding is set to True, the control will use HTTP-chunked encoding when posting, if possible. HTTP-chunked encoding allows large files to be sent in chunks instead of all at once. If set to False, the control will not use HTTP-chunked encoding. The default value is False.

Note: Some servers (such as the ASP.NET Development Server) may not support chunked encoding.

UseIDNs:   Whether to encode hostnames to internationalized domain names.

This configuration setting specifies whether hostnames containing non-ASCII characters are encoded to internationalized domain names. When set to True, if a hostname contains non-ASCII characters, it is encoded using Punycode to an IDN (internationalized domain name).

The default value is False and the hostname will always be used exactly as specified. Note: The CodePage setting must be set to a value capable of interpreting the specified host name. For instance, to specify UTF-8, set CodePage to 65001.

UseProxyAutoConfigURL:   Whether to use a Proxy auto-config file when attempting a connection.

This configuration specifies whether the control will attempt to use the Proxy auto-config URL when establishing a connection and ProxyAutoDetect is set to True.

When True (default), the control will check for the existence of a Proxy auto-config URL, and if found, will determine the appropriate proxy to use.

UserAgent:   Information about the user agent (browser).

This is the value supplied in the HTTP User-Agent header. The default setting is "IPWorks HTTP Component - www.nsoftware.com".

Override the default with the name and version of your software.

TCPClient Config Settings

ConnectionTimeout:   Sets a separate timeout value for establishing a connection.

When set, this configuration setting allows you to specify a different timeout value for establishing a connection. Otherwise, the control will use Timeout for establishing a connection and transmitting/receiving data.

FirewallAutoDetect:   Tells the control whether or not to automatically detect and use firewall system settings, if available.

This configuration setting is provided for use by controls that do not directly expose Firewall properties.

FirewallHost:   Name or IP address of firewall (optional).

If a FirewallHost is given, requested connections will be authenticated through the specified firewall when connecting.

If the FirewallHost setting is set to a Domain Name, a DNS request is initiated. Upon successful termination of the request, the FirewallHost setting is set to the corresponding address. If the search is not successful, an error is returned.

Note: This setting is provided for use by controls that do not directly expose Firewall properties.

FirewallPassword:   Password to be used if authentication is to be used when connecting through the firewall.

If FirewallHost is specified, the FirewallUser and FirewallPassword settings are used to connect and authenticate to the given firewall. If the authentication fails, the control fails with an error.

Note: This setting is provided for use by controls that do not directly expose Firewall properties.

FirewallPort:   The TCP port for the FirewallHost;.

The FirewallPort is set automatically when FirewallType is set to a valid value.

Note: This configuration setting is provided for use by controls that do not directly expose Firewall properties.

FirewallType:   Determines the type of firewall to connect through.

The appropriate values are as follows:

0No firewall (default setting).
1Connect through a tunneling proxy. FirewallPort is set to 80.
2Connect through a SOCKS4 Proxy. FirewallPort is set to 1080.
3Connect through a SOCKS5 Proxy. FirewallPort is set to 1080.
10Connect through a SOCKS4A Proxy. FirewallPort is set to 1080.

Note: This setting is provided for use by controls that do not directly expose Firewall properties.

FirewallUser:   A user name if authentication is to be used connecting through a firewall.

If the FirewallHost is specified, the FirewallUser and FirewallPassword settings are used to connect and authenticate to the Firewall. If the authentication fails, the control fails with an error.

Note: This setting is provided for use by controls that do not directly expose Firewall properties.

KeepAliveInterval:   The retry interval, in milliseconds, to be used when a TCP keep-alive packet is sent and no response is received.

When set, TCPKeepAlive will automatically be set to True. A TCP keep-alive packet will be sent after a period of inactivity as defined by KeepAliveTime. If no acknowledgment is received from the remote host, the keep-alive packet will be sent again. This configuration setting specifies the interval at which the successive keep-alive packets are sent in milliseconds. This system default if this value is not specified here is 1 second.

Note: This value is not applicable in macOS.

KeepAliveTime:   The inactivity time in milliseconds before a TCP keep-alive packet is sent.

When set, TCPKeepAlive will automatically be set to True. By default, the operating system will determine the time a connection is idle before a Transmission Control Protocol (TCP) keep-alive packet is sent. This system default if this value is not specified here is 2 hours. In many cases, a shorter interval is more useful. Set this value to the desired interval in milliseconds.

Linger:   When set to True, connections are terminated gracefully.

This property controls how a connection is closed. The default is True.

In the case that Linger is True (default), two scenarios determine how long the connection will linger. In the first, if LingerTime is 0 (default), the system will attempt to send pending data for a connection until the default IP timeout expires.

In the second scenario, if LingerTime is a positive value, the system will attempt to send pending data until the specified LingerTime is reached. If this attempt fails, then the system will reset the connection.

The default behavior (which is also the default mode for stream sockets) might result in a long delay in closing the connection. Although the control returns control immediately, the system could hold system resources until all pending data are sent (even after your application closes).

Setting this property to False forces an immediate disconnection. If you know that the other side has received all the data you sent (e.g., by a client acknowledgment), setting this property to False might be the appropriate course of action.

LingerTime:   Time in seconds to have the connection linger.

LingerTime is the time, in seconds, the socket connection will linger. This value is 0 by default, which means it will use the default IP timeout.

LocalHost:   The name of the local host through which connections are initiated or accepted.

The LocalHost setting contains the name of the local host as obtained by the gethostname() system call, or if the user has assigned an IP address, the value of that address.

In multi-homed hosts (machines with more than one IP interface) setting LocalHost to the value of an interface will make the control initiate connections (or accept in the case of server controls) only through that interface.

If the control is connected, the LocalHost setting shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multi-homed hosts (machines with more than one IP interface).

LocalPort:   The port in the local host where the control binds.

This must be set before a connection is attempted. It instructs the control to bind to a specific port (or communication endpoint) in the local machine.

Setting this to 0 (default) enables the system to choose a port at random. The chosen port will be shown by LocalPort after the connection is established.

LocalPort cannot be changed once a connection is made. Any attempt to set this when a connection is active will generate an error.

This; setting is useful when trying to connect to services that require a trusted port in the client side. An example is the remote shell (rsh) service in UNIX systems.

MaxLineLength:   The maximum amount of data to accumulate when no EOL is found.

MaxLineLength is the size of an internal buffer, which holds received data while waiting for an EOL string.

If an EOL string is found in the input stream before MaxLineLength bytes are received, the DataIn event is fired with the EOL parameter set to True, and the buffer is reset.

If no EOL is found, and MaxLineLength bytes are accumulated in the buffer, the DataIn event is fired with the EOL parameter set to False, and the buffer is reset.

The minimum value for MaxLineLength is 256 bytes. The default value is 2048 bytes.

MaxTransferRate:   The transfer rate limit in bytes per second.

This configuration setting can be used to throttle outbound TCP traffic. Set this to the number of bytes to be sent per second. By default, this is not set and there is no limit.

ProxyExceptionsList:   A semicolon separated list of hosts and IPs to bypass when using a proxy.

This configuration setting optionally specifies a semicolon-separated list of hostnames or IP addresses to bypass when a proxy is in use. When requests are made to hosts specified in this property, the proxy will not be used. For instance:

www.google.com;www.nsoftware.com

TCPKeepAlive:   Determines whether or not the keep alive socket option is enabled.

If set to True, the socket's keep-alive option is enabled and keep-alive packets will be sent periodically to maintain the connection. Set KeepAliveTime and KeepAliveInterval to configure the timing of the keep-alive packets.

Note: This value is not applicable in Java.

TcpNoDelay:   Whether or not to delay when sending packets.

When true, the socket will send all data that is ready to send at once. When false, the socket will send smaller buffered packets of data at small intervals. This is known as the Nagle algorithm.

By default, this config is set to false.

UseIPv6:   Whether to use IPv6.

When set to 0 (default), the control will use IPv4 exclusively. When set to 1, the control will use IPv6 exclusively. To instruct the control to prefer IPv6 addresses, but use IPv4 if IPv6 is not supported on the system, this setting should be set to 2. The default value is 0. Possible values are:

0 IPv4 Only
1 IPv6 Only
2 IPv6 with IPv4 fallback

SSL Config Settings

LogSSLPackets:   Controls whether SSL packets are logged when using the internal security API.

When SSLProvider is set to Internal, this setting controls whether SSL packets should be logged. By default, this setting is False, as it is only useful for debugging purposes.

When enabled, SSL packet logs are output using the SSLStatus event, which will fire each time an SSL packet is sent or received.

Enabling this setting has no effect if SSLProvider is set to Platform.

OpenSSLCADir:   The path to a directory containing CA certificates.

This functionality is available only when the provider is OpenSSL.

The path set by this property should point to a directory containing CA certificates in PEM format. The files each contain one CA certificate. The files are looked up by the CA subject name hash value, which must hence be available. If more than one CA certificate with the same name hash value exist, the extension must be different (e.g. 9d66eef0.0, 9d66eef0.1 etc). OpenSSL recommends to use the c_rehash utility to create the necessary links. Please refer to the OpenSSL man page SSL_CTX_load_verify_locations(3) for details.

OpenSSLCAFile:   Name of the file containing the list of CA's trusted by your application.

This functionality is available only when the provider is OpenSSL.

The file set by this property should contain a list of CA certificates in PEM format. The file can contain several CA certificates identified by

-----BEGIN CERTIFICATE-----

... (CA certificate in base64 encoding) ...

-----END CERTIFICATE-----

sequences. Before, between, and after the certificates text is allowed which can be used e.g. for descriptions of the certificates. Please refer to the OpenSSL man page SSL_CTX_load_verify_locations(3) for details.

OpenSSLCipherList:   A string that controls the ciphers to be used by SSL.

This functionality is available only when the provider is OpenSSL.

The format of this string is described in the OpenSSL man page ciphers(1) section "CIPHER LIST FORMAT". Please refer to it for details. The default string "DEFAULT" is determined at compile time and is normally equivalent to "ALL:!ADH:RC4+RSA:+SSLv2:@STRENGTH".

OpenSSLPrngSeedData:   The data to seed the pseudo random number generator (PRNG).

This functionality is available only when the provider is OpenSSL.

By default OpenSSL uses the device file "/dev/urandom" to seed the PRNG and setting OpenSSLPrngSeedData is not required. If set, the string specified is used to seed the PRNG.

ReuseSSLSession:   Determines if the SSL session is reused.

If set to true, the control will reuse the context if and only if the following criteria are met:

  • The target host name is the same.
  • The system cache entry has not expired (default timeout is 10 hours).
  • The application process that calls the function is the same.
  • The logon session is the same.
  • The instance of the control is the same.

SSLCACerts:   A newline separated list of CA certificate to use during SSL client authentication.

This setting specifies one or more CA certificates to be included in the request when performing SSL client authentication. Some servers require the entire chain, including CA certificates, to be presented when performing SSL client authentication. The value of this setting is a newline (CrLf) separated list of certificates. For instance:

-----BEGIN CERTIFICATE-----
MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw
...
eWHV5OW1K53o/atv59sOiW5K3crjFhsBOd5Q+cJJnU+SWinPKtANXMht+EDvYY2w
F0I1XhM+pKj7FjDr+XNj
-----END CERTIFICATE-----
\r \n
-----BEGIN CERTIFICATE-----
MIIEFjCCAv6gAwIBAgIQetu1SMxpnENAnnOz1P+PtTANBgkqhkiG9w0BAQUFADBp
..
d8q23djXZbVYiIfE9ebr4g3152BlVCHZ2GyPdjhIuLeH21VbT/dyEHHA
-----END CERTIFICATE-----

SSLCheckCRL:   Whether to check the Certificate Revocation List for the server certificate.

This setting specifies whether the control will check the Certificate Revocation List specified by the server certificate. If set to 1 or 2, the control will first obtain the list of CRL URLs from the server certificate's CRL distribution points extension. The control will then make HTTP requests to each CRL endpoint to check the validity of the server's certificate. If the certificate has been revoked or any other issues are found during validation the control fails with an error.

When set to 0 (default) the CRL check will not be performed by the control. When set to 1, it will attempt to perform the CRL check, but will continue without an error if the server's certificate does not support CRL. When set to 2, it will perform the CRL check and will throw an error if CRL is not supported.

This configuration setting is only supported in the Java, C#, and C++ editions. In the C++ edition, it is only supported on Windows operating systems.

SSLCheckOCSP:   Whether to use OCSP to check the status of the server certificate.

This setting specifies whether the control will use OCSP to check the validity of the server certificate. If set to 1 or 2, the control will first obtain the OCSP URL from the server certificate's OCSP extension. The control will then locate the issuing certificate and make an HTTP request to the OCSP endpoint to check the validity of the server's certificate. If the certificate has been revoked or any other issues are found during validation the control fails with an error.

When set to 0 (default) the control will not perform an OCSP check. When set to 1, it will attempt to perform the OCSP check, but will continue without an error if the server's certificate does not support OCSP. When set to 2, it will perform the OCSP check and will throw an error if OCSP is not supported.

This configuration setting is only supported in the Java, C#, and C++ editions. In the C++ edition, it is only supported on Windows operating systems.

SSLCipherStrength:   The minimum cipher strength used for bulk encryption.

This minimum cipher strength largely dependent on the security modules installed on the system. If the cipher strength specified is not supported, an error will be returned when connections are initiated.

Please note that this setting contains the minimum cipher strength requested from the security library. The actual cipher strength used for the connection is shown by the SSLStatus event.

Use this setting with caution. Requesting a lower cipher strength than necessary could potentially cause serious security vulnerabilities in your application.

When the provider is OpenSSL, SSLCipherStrength is currently not supported. This functionality is instead made available through the OpenSSLCipherList config setting.

SSLEnabledCipherSuites:   The cipher suite to be used in an SSL negotiation.

The enabled cipher suites to be used in SSL negotiation.

By default, the enabled cipher suites will include all available ciphers ("*").

The special value "*" means that the control will pick all of the supported cipher suites. If SSLEnabledCipherSuites is set to any other value, only the specified cipher suites will be considered.

Multiple cipher suites are separated by semicolons.

Example values when SSLProvider is set to Platform: obj.config("SSLEnabledCipherSuites=*"); obj.config("SSLEnabledCipherSuites=CALG_AES_256"); obj.config("SSLEnabledCipherSuites=CALG_AES_256;CALG_3DES"); Possible values when SSLProvider is set to Platform include:

SSLEnabledProtocols:   Used to enable/disable the supported security protocols.

Used to enable/disable the supported security protocols.

Not all supported protocols are enabled by default (the value of this setting is 4032). If you want more granular control over the enabled protocols, you can set this property to the binary 'OR' of one or more of the following values:

TLS1.312288 (Hex 3000)
TLS1.23072 (Hex C00) (Default)
TLS1.1768 (Hex 300) (Default)
TLS1 192 (Hex C0) (Default)
SSL3 48 (Hex 30)
SSL2 12 (Hex 0C)

SSLEnabledProtocols - TLS 1.3 Notes

By default when TLS 1.3 is enabled the control will use the internal TLS implementation when the SSLProvider is set to Automatic for all editions.

In editions which are designed to run on Windows SSLProvider can be set to Platform to use the platform implementation instead of the internal implementation. When configured in this manner, please note that the platform provider is only supported on Windows 11 / Windows Server 2022 and up. The default internal provider is available on all platforms and is not restricted to any specific OS version.

If set to 1 (Platform provider) please be aware of the following notes:

  • The platform provider is only available on Windows 11 / Windows Server 2022 and up.
  • SSLEnabledCipherSuites and other similar SSL configuration settings are not supported.
  • If SSLEnabledProtocols includes both TLS 1.3 and TLS 1.2 the above restrictions are still applicable even if TLS 1.2 is negotiated. Enabling TLS 1.3 with the platform provider changes the implementation used for all TLS versions.

SSLEnableRenegotiation:   Whether the renegotiation_info SSL extension is supported.

This setting specifies whether the renegotiation_info SSL extension will be used in the request when using the internal security API. This setting is by default, but can be set to to disable the extension.

This setting is only applicable when SSLProvider is set to Internal.

SSLIncludeCertChain:   Whether the entire certificate chain is included in the SSLServerAuthentication event.

This setting specifies whether the Encoded parameter of the SSLServerAuthentication event contains the full certificate chain. By default this value is False and only the leaf certificate will be present in the Encoded parameter of the SSLServerAuthentication event.

If set to True all certificates returned by the server will be present in the Encoded parameter of the SSLServerAuthentication event. This includes the leaf certificate, any intermediate certificate, and the root certificate.

SSLKeyLogFile:   The location of a file where per-session secrets are written for debugging purposes.

This setting optionally specifies the full path to a file on disk where per-session secrets are stored for debugging purposes.

When set, the control will save the session secrets in the same format as the SSLKEYLOGFILE environment variable functionality used by most major browsers and tools such as Chrome, Firefox, and cURL. This file can then be used in tools such as Wireshark to decrypt TLS traffice for debugging purposes. When writing to this file the control will only append, it will not overwrite previous values.

Note: This setting is only applicable when SSLProvider is set to Internal.

SSLNegotiatedCipher:   Returns the negotiated cipher suite.

Returns the cipher suite negotiated during the SSL handshake.

Note: For server components (e.g. TCPServer) this is a per-connection setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedCipher[connId]");

SSLNegotiatedCipherStrength:   Returns the negotiated cipher suite strength.

Returns the strength of the cipher suite negotiated during the SSL handshake.

Note: For server components (e.g.TCPServer) this is a per-connection setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedCipherStrength[connId]");

SSLNegotiatedCipherSuite:   Returns the negotiated cipher suite.

Returns the cipher suite negotiated during the SSL handshake represented as a single string.

Note: For server components (e.g. TCPServer) this is a per-connection setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedCipherSuite[connId]");

SSLNegotiatedKeyExchange:   Returns the negotiated key exchange algorithm.

Returns the key exchange algorithm negotiated during the SSL handshake.

Note: For server components (e.g. TCPServer) this is a per-connection setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedKeyExchange[connId]");

SSLNegotiatedKeyExchangeStrength:   Returns the negotiated key exchange algorithm strength.

Returns the strenghth of the key exchange algorithm negotiated during the SSL handshake.

Note: For server components (e.g. TCPServer) this is a per-connection setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedKeyExchangeStrength[connId]");

SSLNegotiatedVersion:   Returns the negotiated protocol version.

Returns the protocol version negotiated during the SSL handshake.

Note: For server components (e.g. TCPServer) this is a per-connection setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedVersion[connId]");

SSLSecurityFlags:   Flags that control certificate verification.

The following flags are defined (specified in hexadecimal notation). They can be or-ed together to exclude multiple conditions:

0x00000001Ignore time validity status of certificate.
0x00000002Ignore time validity status of CTL.
0x00000004Ignore non-nested certificate times.
0x00000010Allow unknown Certificate Authority.
0x00000020Ignore wrong certificate usage.
0x00000100Ignore unknown certificate revocation status.
0x00000200Ignore unknown CTL signer revocation status.
0x00000400Ignore unknown Certificate Authority revocation status.
0x00000800Ignore unknown Root revocation status.
0x00008000Allow test Root certificate.
0x00004000Trust test Root certificate.
0x80000000Ignore non-matching CN (certificate CN not-matching server name).

This functionality is currently not available when the provider is OpenSSL.

SSLServerCACerts:   A newline separated list of CA certificate to use during SSL server certificate validation.

This setting optionally specifies one or more CA certificates to be used when verifying the server certificate. When verifying the server's certificate the certificates trusted by the system will be used as part of the verification process. If the server's CA certificates are not installed to the trusted system store, they may be specified here so they are included when performing the verification process. This setting should only be set if the server's CA certificates are not already trusted on the system and cannot be installed to the trusted system store.

The value of this setting is a newline (CrLf) separated list of certificates. For instance:

-----BEGIN CERTIFICATE-----
MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw

-----END CERTIFICATE-----

TLS12SignatureAlgorithms:   Defines the allowed TLS 1.2 signature algorithms when SSLProvider is set to Internal.

This setting specifies the allowed server certificate signature algorithms when SSLProvider is set to Internal and SSLEnabledProtocols is set to allow TLS 1.2.

When specified the control will verify that the server certificate signature algorithm is among the values specified in this setting. If the server certificate signature algorithm is unsupported the control fails with an error.

The format of this value is a comma separated list of hash-signature combinations. For instance: component.SSLProvider = TCPClientSSLProviders.sslpInternal; component.Config("SSLEnabledProtocols=3072"); //TLS 1.2 component.Config("TLS12SignatureAlgorithms=sha256-rsa,sha256-dsa,sha1-rsa,sha1-dsa"); The default value for this setting is sha512-ecdsa,sha512-rsa,sha512-dsa,sha384-ecdsa,sha384-rsa,sha384-dsa,sha256-ecdsa,sha256-rsa,sha256-dsa,sha224-ecdsa,sha224-rsa,sha224-dsa,sha1-ecdsa,sha1-rsa,sha1-dsa.

In order to not restrict the server's certificate signature algorithm, specify an empty string as the value for this setting, which will cause the signature_algorithms TLS 1.2 extension to not be sent.

TLS12SupportedGroups:   The supported groups for ECC.

This setting specifies a comma separated list of named groups used in TLS 1.2 for ECC.

The default value is ecdhe_secp256r1,ecdhe_secp384r1,ecdhe_secp521r1.

When using TLS 1.2 and SSLProvider is set to Internal, the values refer to the supported groups for ECC. The following values are supported:

  • "ecdhe_secp256r1" (default)
  • "ecdhe_secp384r1" (default)
  • "ecdhe_secp521r1" (default)

TLS13KeyShareGroups:   The groups for which to pregenerate key shares.

This setting specifies a comma separated list of named groups used in TLS 1.3 for key exchange. The groups specified here will have key share data pregenerated locally before establishing a connection. This can prevent an additional round trip during the handshake if the group is supported by the server.

The default value is set to balance common supported groups and the computational resources required to generate key shares. As a result only some groups are included by default in this setting.

Note: All supported groups can always be used during the handshake even if not listed here, but if a group is used which is not present in this list it will incur an additional round trip and time to generate the key share for that group.

In most cases this setting does not need to be modified. This should only be modified if there is a specific reason to do so.

The default value is ecdhe_x25519,ecdhe_secp256r1,ecdhe_secp384r1,ffdhe_2048,ffdhe_3072

The values are ordered from most preferred to least preferred. The following values are supported:

  • "ecdhe_x25519" (default)
  • "ecdhe_x448"
  • "ecdhe_secp256r1" (default)
  • "ecdhe_secp384r1" (default)
  • "ecdhe_secp521r1"
  • "ffdhe_2048" (default)
  • "ffdhe_3072" (default)
  • "ffdhe_4096"
  • "ffdhe_6144"
  • "ffdhe_8192"

TLS13SignatureAlgorithms:   The allowed certificate signature algorithms.

This setting holds a comma separated list of allowed signature algorithms. Possible values are:

  • "ed448" (default)
  • "ecdsa_secp256r1_sha256" (default)
  • "ecdsa_secp384r1_sha384" (default)
  • "ecdsa_secp521r1_sha512" (default)
  • "rsa_pkcs1_sha256" (default)
  • "rsa_pkcs1_sha384" (default)
  • "rsa_pkcs1_sha512" (default)
  • "rsa_pss_sha256" (default)
  • "rsa_pss_sha384" (default)
  • "rsa_pss_sha512" (default)
The default value is rsa_pss_sha256,rsa_pss_sha384,rsa_pss_sha512,rsa_pkcs1_sha256,rsa_pkcs1_sha384,rsa_pkcs1_sha512,ecdsa_secp256r1_sha256,ecdsa_secp384r1_sha384,ecdsa_secp521r1_sha512,ed25519,ed448. This setting is only applicable when SSLEnabledProtocols includes TLS 1.3.
TLS13SupportedGroups:   The supported groups for (EC)DHE key exchange.

This setting specifies a comma separated list of named groups used in TLS 1.3 for key exchange. This setting should only be modified if there is a specific reason to do so.

The default value is ecdhe_x25519,ecdhe_x448,ecdhe_secp256r1,ecdhe_secp384r1,ecdhe_secp521r1,ffdhe_2048,ffdhe_3072,ffdhe_4096,ffdhe_6144,ffdhe_8192

The values are ordered from most preferred to least preferred. The following values are supported:

  • "ecdhe_x25519" (default)
  • "ecdhe_x448" (default)
  • "ecdhe_secp256r1" (default)
  • "ecdhe_secp384r1" (default)
  • "ecdhe_secp521r1" (default)
  • "ffdhe_2048" (default)
  • "ffdhe_3072" (default)
  • "ffdhe_4096" (default)
  • "ffdhe_6144" (default)
  • "ffdhe_8192" (default)

Socket Config Settings

AbsoluteTimeout:   Determines whether timeouts are inactivity timeouts or absolute timeouts.

If AbsoluteTimeout is set to True, any method which does not complete within Timeout seconds will be aborted. By default, AbsoluteTimeout is False, and the timeout is an inactivity timeout.

Note: This option is not valid for UDP ports.

FirewallData:   Used to send extra data to the firewall.

When the firewall is a tunneling proxy, use this property to send custom (additional) headers to the firewall (e.g. headers for custom authentication schemes).

InBufferSize:   The size in bytes of the incoming queue of the socket.

This is the size of an internal queue in the TCP/IP stack. You can increase or decrease its size depending on the amount of data that you will be receiving. Increasing the value of the InBufferSize setting can provide significant improvements in performance in some cases.

Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the control is activated the InBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.

OutBufferSize:   The size in bytes of the outgoing queue of the socket.

This is the size of an internal queue in the TCP/IP stack. You can increase or decrease its size depending on the amount of data that you will be sending. Increasing the value of the OutBufferSize setting can provide significant improvements in performance in some cases.

Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the control is activated the OutBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.
