The XMLEncrypt component is used to encrypt and decrypt XML.

Syntax

nsoftware.IPWorksEncrypt.Xmlencrypt

Remarks

The XMLEncrypt component provides a simple API for encrypting and decrypting XML. The Encrypt method will encrypt the XML document, or a specific element. Multiple elements may be encrypted at one time by setting EncryptedDataDetails. The Decrypt method will decrypt the XML document.

The component supports encrypting and decrypting with a shared SymmetricKey, and also using asymmetric encryption to encrypt the SymmetricKey (session key) via the RecipientCert and Certificate properties.

Encrypt

To begin first specify a XML document by calling SetInputStream or setting InputFile, or InputXML.

The EncryptedDataDetails property specify the XML element to encrypt. By default the entire XML document is encrypted.

The SymmetricKey property specifies the key which will be used to encrypt the data.

If the RecipientCert property is set, then the SymmetricKey will be encrypted and included in the encrypted data. This allows for the recipient to decrypt the key, with their certificate. Encrypting the symmetric key is also referred to as using a session key. The benefit of using certificate to encrypt and decrypt a session key (SymmetricKey) is that knowledge of the key value is not needed ahead of time to process the encrypted data. Note that if specified, RecipientCert MUST have a RSA key, not a DSA key.

If the RecipientCert property is not set, then the recipient must know the value of SymmetricKey before decrypting the XML. The KeyName setting may be set to provide a key identifier to the recipient.

Optionally set EncryptingAlgorithm, and then call Encrypt to encrypt the XML.

The following properties are applicable when calling this method:

Input and Output Properties

The component will determine the source and destination of the input and output based on which properties are set.

The order in which the input properties are checked is as follows:

When a valid source is found the search stops. The order in which the output properties are checked is as follows:

Decrypt

To begin first specify a XML document by calling SetInputStream or setting InputFile, or InputXML.

The SymmetricKey property specifies the key used to decrypt the data. This may be set before calling Decrypt or inside the EncryptedDataInfo event. The EncryptedDataInfo event fires once for each encrypted element when Decrypt is called.

If the data was encrypted using an session key, set the Certificate property to the certificate with private key before calling Decrypt. The certificate will be used to decrypt the encrypted session key. In this case the SymmetricKey property is ignored.

The following properties are applicable when calling this method:

17 (cstXMLBlob)The certificate store is a string that contains a certificate in XML format.
18 (cstJWKFile)The certificate store is the name of a file that contains a JWK (JSON Web Key).
19 (cstJWKBlob)The certificate store is a string that contains a JWK (JSON Web Key).
21 (cstBCFKSFile)The certificate store is the name of a file that contains a BCFKS (Bouncy Castle FIPS Key Store). Note: this store type is only available in Java and .NET.
22 (cstBCFKSBlob)The certificate store is a string (binary or base64-encoded) representing a certificate store in BCFKS (Bouncy Castle FIPS Key Store) format. Note: this store type is only available in Java and .NET.
23 (cstPKCS11)The certificate is present on a physical security key accessible via a PKCS11 interface.

To use a security key the necessary data must first be collected using the CertMgr component. The ListStoreCertificates method may be called after setting CertStoreType to cstPKCS11, CertStorePassword to the PIN, and CertStore to the full path of the PKCS11 dll. The certificate information returned in the CertList event's CertEncoded parameter may be saved for later use.

When using a certificate, pass the previously saved security key information as the Store and set StorePassword to the PIN.

Code Example: SSH Authentication with Security Key certmgr.CertStoreType = CertStoreTypes.cstPKCS11; certmgr.OnCertList += (s, e) => { secKeyBlob = e.CertEncoded; }; certmgr.CertStore = @"C:\Program Files\OpenSC Project\OpenSC\pkcs11\opensc-pkcs11.dll"; certmgr.CertStorePassword = "123456"; //PIN certmgr.ListStoreCertificates(); sftp.SSHCert = new Certificate(CertStoreTypes.cstPKCS11, secKeyBlob, "123456", "*"); sftp.SSHUser = "test"; sftp.SSHLogon("myhost", 22);

99 (cstAuto)The store type is automatically detected from the input data. This setting may be used with both public and private keys and can detect any of the supported formats automatically.

Subject
String

This is the subject of the certificate used for client authentication.

This field will be populated with the full subject of the loaded certificate. When loading a certificate the subject is used to locate the certificate in the store.

If an exact match is not found, the store is searched for subjects containing the value of the property.

If a match is still not found, the property is set to an empty string, and no certificate is selected.

The special value "*" picks a random certificate in the certificate store.

The certificate subject is a comma separated list of distinguished name fields and values. For instance "CN=www.server.com, OU=test, C=US, E=support@nsoftware.com". Common fields and their meanings are displayed below.

FieldMeaning
CNCommon Name. This is commonly a host name like www.server.com.
OOrganization
OUOrganizational Unit
LLocality
SState
CCountry
EEmail Address

If a field value contains a comma it must be quoted.

SubjectAltNames
String

This field contains comma-separated lists of alternative subject names for the certificate.

ThumbprintMD5
String

This field contains the MD5 hash of the certificate. If the hash does not already exist, it is computed.

ThumbprintSHA1
String

This field contains the SHA-1 hash of the certificate. If the hash does not already exist, it is computed.

Config Settings (XMLEncrypt Component)

The component 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 component, access to these internal properties is provided through the Config method.

XMLEnc Config Settings

EncryptedKeyXPath:   The XPath of the EncryptedKey element.

This setting specifies the XPath where the EncryptedKey element will be written. In most cases this does not need to be changed. By default it is included in the EncryptedData element.

KeyName:   The name of the key used to encrypt the XML.

This setting optionally holds the key name which may be useful to the recipient to help identify the key used to encrypt the data. This may be set before calling Encrypt. When calling Decrypt this may be queried inside the EncryptedDataInfo event.

Note that this value is only informative, it does not affect processing.

LogLevel:   Specifies the level of detail that is logged.

This setting controls the level of detail that is logged through the Status event. Possible values are:

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

OAEPMGF1HashAlgorithm:   The MGF1 hash algorithm used with OAEP.

This configuration setting specifies the MGF1 hash algorithm used when UseOAEP is set to True. The default value is SHA256. Possible values are as follows:

  • "SHA1"
  • "SHA224"
  • "SHA256" (default)
  • "SHA384"
  • "SHA512"
  • "RIPEMD160"
  • "MD2"
  • "MD5"
  • "MD5SHA1"
OAEPParams:   The hex encoded OAEP parameters.

This configuration setting optionally specifies Optimal Asymmetric Encryption Padding (OAEP) parameters to be used when UseOAEP is set to True. The specified value should be hex encoded.

OAEPRSAHashAlgorithm:   The RSA hash algorithm used with OAEP.

This configuration setting specifies that RSA hash algorithm used when UseOAEP is set to True. The default value is SHA256. Possible values are as follows:

  • "SHA1"
  • "SHA224"
  • "SHA256" (default)
  • "SHA384"
  • "SHA512"
  • "RIPEMD160"
  • "MD2"
  • "MD5"
  • "MD5SHA1"
The RSA hash algorithm used when encrypting a key.

When encryption is enabled, this algorithm specifies the RSA hash algorithm used for the encryption key. This may differ from the hash algorithm used to sign the message content. Possible values are:

  • "SHA1" (default)
  • "SHA224"
  • "SHA256"
  • "SHA384"
  • "SHA512"
OAEPRSAHashAlgorithm:   The RSA hash algorithm used with OAEP.

This configuration setting specifies that RSA hash algorithm used when UseOAEP is set to True. The default value is SHA256. Possible values are as follows:

  • "SHA1"
  • "SHA224"
  • "SHA256" (default)
  • "SHA384"
  • "SHA512"
  • "RIPEMD160"
  • "MD2"
  • "MD5"
  • "MD5SHA1"
The RSA hash algorithm used when encrypting a key.

When encryption is enabled, this algorithm specifies the RSA hash algorithm used for the encryption key. This may differ from the hash algorithm used to sign the message content. Possible values are:

  • "SHA1" (default)
  • "SHA224"
  • "SHA256"
  • "SHA384"
  • "SHA512"
ReadFromProgressEvent:   Whether to read input data from inside the progress event.

When set to True this setting allows input data to be specified from within the Progress event. The component will repeatedly fire the Progress event to ask for data. Inside the event set InputXML when the Operation parameter of the event is 1 (Read). When all data has been provided set the IsEOF parameter of the event to True. This allows input data to be chunked and provided piece by piece. The default value is False.

WriteToProgressEvent:   Whether to write output data so it is accessible from inside the progress event.

When set to True this setting allows output data to be obtained from within the Progress event. The component will repeatedly fire the Progress event to provide output data. Inside the event check OutputXML when the Operation parameter of the event is 2 (Write). The IsEOF parameter should be checked inside the event to determine when all output data has been provided. This allows output data to be chunked and obtained piece by piece. The default value is False.

Base Config Settings

BuildInfo:   Information about the product's build.

When queried, this setting will return a string containing information about the product's build.

GUIAvailable:   Tells the component whether or not a message loop is available for processing events.

In a GUI-based application, long-running blocking operations may cause the application to stop responding to input until the operation returns. The component will attempt to discover whether or not the application has a message loop and, if one is discovered, it will process events in that message loop during any such blocking operation.

In some non-GUI applications, an invalid message loop may be discovered that will result in errant behavior. In these cases, setting GUIAvailable to false will ensure that the component does not attempt to process external events.

LicenseInfo:   Information about the current license.

When queried, this setting will return a string containing information about the license this instance of a component is using. It will return the following information:

  • Product: The product the license is for.
  • Product Key: The key the license was generated from.
  • License Source: Where the license was found (e.g., RuntimeLicense, License File).
  • License Type: The type of license installed (e.g., Royalty Free, Single Server).
  • Last Valid Build: The last valid build number for which the license will work.
MaskSensitive:   Whether sensitive data is masked in log messages.

In certain circumstances it may be beneficial to mask sensitive data, like passwords, in log messages. Set this to true to mask sensitive data. The default is false.

This setting only works on these components: AS3Receiver, AS3Sender, Atom, Client(3DS), FTP, FTPServer, IMAP, OFTPClient, SSHClient, SCP, Server(3DS), Sexec, SFTP, SFTPServer, SSHServer, TCPClient, TCPServer.

UseInternalSecurityAPI:   Tells the component whether or not to use the system security libraries or an internal implementation.

When set to false, the component will use the system security libraries by default to perform cryptographic functions where applicable. In this case, calls to unmanaged code will be made. In certain environments this is not desirable. To use a completely managed security implementation set this setting to true.

Setting this setting to true tells the component to use the internal implementation instead of using the system security libraries.

On Windows, this setting is set to false by default. On Linux/macOS, this setting is set to true by default.

If using the .NET Standard Library, this setting will be true on all platforms. The .NET Standard library does not support using the system security libraries.

Note: This setting is static. The value set is applicable to all components used in the application.

When this value is set the product's system DLL is no longer required as a reference, as all unmanaged code is stored in that file.
