OpenPGP Control

Properties Methods Events Config Settings Errors

The OpenPGP control is used to encrypt/decrypt and sign/verify PGP messages.

Syntax

OpenPGP

Remarks

The OpenPGP control supports encrypting/decrypting and signing/verifying OpenPGP messages. Supported message formats are specified by RFC 4880, in addition to RFC 9580, which introduces support for OpenPGP Version 6.

The Encrypt, Sign, and SignAndEncrypt methods are used to create a message to be sent to your partner. You can additionally create messages bound for multiple recipients with different keys, simultaneously encrypt and compress with the most popular compression algorithms, and control other aspects such as the encrypting algorithm to use.

When a message is received, the Decrypt, VerifySignature, and DecryptAndVerifySignature methods are used to process the incoming message.

The Keys property holds the key (with private key) used to sign and decrypt.

The SignerKeys property holds the key used to verify a signature.

The RecipientKeys property holds the key used to encrypt.

Input and Output Properties

The control 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:

InputFile
InputMessage

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

OutputFile
OutputMessage: The output data is written to this property if no other destination is specified.

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.

Decrypt Method (OpenPGP Control)

Within this event you may use the available information to load the correct key into Keys.

DecryptAndVerifySignature Method (OpenPGP Control)

Decrypts and verifies the signature of the message.

Syntax

openpgpcontrol.DecryptAndVerifySignature

Remarks

This method attempts to both decrypt and verify the signature of the message. All of the properties affected by calling the Decrypt and VerifySignature methods are affected in the same manner.

This method may be used when the data is signed, encrypted, or signed and encrypted. For instance, if the data is encrypted but not signed you may still use this method and the control will perform the decryption without error.

The message will be verified using the keys specified in SignerKeys. Before verification begins the control will fire the SignatureInfo event with information about the signature including the key used to sign the message. Within this event you may use the information available to load the correct key into SignerKeys.

By default, if the signature is not valid the control fails with an error. The configuration setting RequireValidSignature may be set to False to disable this requirement. When RequireValidSignature is set to False, the Status parameter of the VerificationStatus event should be checked to determine the result of the operation.

NOTE: This method does not attempt to check the validity of the signing key itself.

Encrypt Method (OpenPGP Control)

Encrypts the message.

Syntax

openpgpcontrol.Encrypt

Remarks

This method encrypts the specified message.

The message is encrypted with the public keys specified in RecipientKeys.

Error Event (OpenPGP Control)

Fired when information is available about errors during data delivery.

Syntax

Sub openpgpcontrol_Error(ErrorCode As Integer, Description As String)

Remarks

The Error event is fired in case of exceptional conditions during message processing. Normally the control fails with an error.

The ErrorCode parameter contains an error code, and the Description parameter contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.

KeyPassphrase Event (OpenPGP Control)

Fired if the passphrase of current key is incorrect or empty.

Syntax

Sub openpgpcontrol_KeyPassphrase(UserId As String, KeyId As String, Fingerprint As String, Passphrase As String)

Remarks

This event fires when the passphrase for the key is required. The passphrase must be specified before operations requiring the secret key are attempted. The passphrase may be supplied by setting the Passphrase parameter in this event, or by specifying the KeyPassphrase property before attempting the operation.

The passphrase is required when using the following methods in KeyMgr:

AddUserId
SignUserId
ChangeExpirationDate
ChangePassphrase

When using the OpenPGP control, or an email-based control, the following methods require a passphrase for the key:

Decrypt
Sign
SignAndEncrypt

UserId holds the user Id of the key the passphrase is required for.

The UserId format is:

FirstName LastName (Comment) <Email>

Not all values are required when selecting or generating a key, but at least FirstName or Email are required.

KeyId is the hex-encoded, 4-byte or 8-byte Id of the key the passphrase is required for. For OpenPGP v4 keys and earlier, the key Id corresponds to the last 4 or 8 bytes of the key's Fingerprint. For OpenPGP v6 keys, the key Id corresponds to the first 8 bytes of the key's Fingerprint instead. For instance:

5E70662EA810E768

Fingerprint holds the hex-encoded, 20-byte fingerprint of the key the passphrase is required for. This is in the form:

5E70662EA810E768391A2FE8F7B7D49C89C9D7B1

Progress Event (OpenPGP Control)

Fired as progress is made.

Syntax

Sub openpgpcontrol_Progress(BytesProcessed As Long64, PercentProcessed As Integer, Operation As Integer, IsEOF As Boolean)

Remarks

This event is fired automatically as data is processed by the control.

The PercentProcessed parameter indicates the current status of the operation.

The BytesProcessed parameter holds the total number of bytes processed so far.

The Operation parameter is only applicable when either ReadFromProgressEvent or WriteToProgressEvent is set to True. This parameter defines whether a Read or Write operation is required. If the configuration settings are not set this parameter will always return 0. Possible values are:


0	None
1	Read
2	Write

The IsEOF parameter is only applicable when either ReadFromProgressEvent or WriteToProgressEvent is set to True. This parameter defines whether the Read or Write operation is complete. When the Operation is Read (1) this parameter must be set to indicate that all data has been supplied to the control. When the Operation is Write (2) this value may be queried to determine when all data has been processed.

RecipientInfo Event (OpenPGP Control)

Fired for each recipient key of the encrypted message.

Syntax

Sub openpgpcontrol_RecipientInfo(KeyId As String, Fingerprint As String, PublicKeyAlgorithm As String)

Remarks

This event fires when the Decrypt or DecryptAndVerifySignature method is called.

KeyId is the hex-encoded 4- or 8-byte Id of the key used to encrypt the message. If a subkey was used to encrypt the message this will be the Id of that subkey. For OpenPGP v4 keys and earlier, the key Id corresponds to the last 4 or 8 bytes of the key's Fingerprint. For OpenPGP v6 keys, the key Id corresponds to the first 8 bytes of the key's Fingerprint instead. For instance:

5E70662EA810E768

Fingerprint holds the hex-encoded, 20-byte fingerprint of the key. This is in the form:

5E70662EA810E768391A2FE8F7B7D49C89C9D7B1

The KeyId and Fingerprint parameters can be used to identify the correct key to specify in the Key* properties. The Key* properties can be set from within this event as this event fires directly before the decryption process begins.

It is recommended to use the Fingerprint to identify the correct key, as it is possible for different keys to have the same KeyId.

PublicKeyAlgorithm is the algorithm of the public key used to encrypt the message. Possible values are:

RSA
DSA
ECDSA
EdDSA
Ed25519
Ed448
RSA-Legacy
ECDH (Subkeys only)
X25519 (Subkeys only)
X448 (Subkeys only)

SignatureInfo Event (OpenPGP Control)

Fired during verification of the signed message.

Syntax

Sub openpgpcontrol_SignatureInfo(KeyId As String, Fingerprint As String, SigningAlgorithm As String, PublicKeyAlgorithm As String)

Remarks

This event fires when the VerifySignature or DecryptAndVerifySignature method is called. It provides information about the signature of the message.

KeyId is the hex-encoded 4- or 8-byte Id of the key used to sign the message. If a subkey was used to sign the message this will be the Id of that subkey. For OpenPGP v4 keys and earlier, the key Id corresponds to the last 4 or 8 bytes of the key's Fingerprint. For OpenPGP v6 keys, the key Id corresponds to the first 8 bytes of the key's Fingerprint instead. For instance:

5E70662EA810E768

Fingerprint holds the hex-encoded, 20-byte fingerprint of the key. This is in the form:

5E70662EA810E768391A2FE8F7B7D49C89C9D7B1

The KeyId and Fingerprint parameters can be used to identify the correct key to specify in the SignerKey* properties. The SignerKey* properties can be set from within this event as this event fires directly before the verification process begins.

It is recommended to use the Fingerprint to identify the correct key, as it is possible for different keys to have the same KeyId.

SigningAlgorithm describes the hash algorithm used when the message was originally signed. This value is applicable only to the message signature, not the key used to sign the message. Possible values are:

SHA1
MD5
SHA256
SHA384
SHA512
SHA224
RIPEMD160
SHA3-256
SHA3-512

PublicKeyAlgorithm is the algorithm of the public key used to sign the message. Possible values are:

RSA
DSA
ECDSA
EdDSA
Ed25519
Ed448
RSA-Legacy
ECDH (Subkeys only)
X25519 (Subkeys only)
X448 (Subkeys only)

Status Event (OpenPGP Control)

Shows the progress of the operation.

Syntax

Sub openpgpcontrol_Status(Message As String)

Remarks

The event is fired for informational and logging purposes only. It may be used to track the progress of an operation.

The level of detail is controlled by the LogLevel setting.

VerificationStatus Event (OpenPGP Control)

Fired after verification of the signed message.

Syntax

Sub openpgpcontrol_VerificationStatus(KeyId As String, Fingerprint As String, Status As Integer)

Remarks

This event fires when VerifySignature or DecryptAndVerifySignature is called. It provides information about the result.

KeyId is the hex-encoded 4- or 8-byte Id of the key used to sign the message. For OpenPGP v4 keys and earlier, the key Id corresponds to the last 4 or 8 bytes of the key's Fingerprint. For OpenPGP v6 keys, the key Id corresponds to the first 8 bytes of the key's Fingerprint instead. For instance:

5E70662EA810E768

Fingerprint holds the hex-encoded, 20-byte fingerprint of the key. This is in the form:

5E70662EA810E768391A2FE8F7B7D49C89C9D7B1

Status holds the result of the operation. Possible values are:


0	Verification succeeded
1	Verification failed
2	The required key could not be found
3	Verification succeeded but the key is expired.

Config Settings (OpenPGP 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.

OpenPGP Config Settings

AEADChunkSizeExp: Specifies the exponent used to calculate the plaintext chunk size for encryption.

This config specifies the exponent used to calculate the plaintext chunk size for encryption. Note this config is only applicable when EncryptingAlgorithm is set to AES*-OCB or AES*-GCM (AEAD encryption algorithms).

By default, this value is 6. Valid values range from 6 to 22.

The chunk size is calculated as 2^exp (in octets, or bytes), where exp is the value of this configuration setting. For example, the default chunk size would be: 2^(6) = 64 bytes. In this case, the plaintext would be split into chunks of 64 bytes, each of which will be individually encrypted using the specified EncryptingAlgorithm.

AllowEmptyInput: Whether to allow empty files for input.

This setting controls whether the control allows empty input when processing. When True, the control will process 0 byte files specified by InputFile, or 0 byte messages specified by InputMessage. The default value is False.

AllowOldPacketType: Whether to allow the older encrypted packet type.

By default the control will only encrypt data using the newer and more secure integrity protected data packet type. Old implementations such as PGP 6.5.8 may require the older less secure data packet type.

When set to True the control will read the features from the recipient key to determine if the older packet type is required. If the key does require the old packet type, then the older packet type will be used. If the key does not require the old packet type, then the new integrity protected packet type will still be used.

By default this value is False. This means under no conditions is the older less secure packet type used. The newer integrity protected packet type is always used.

Only enable this setting if you have a requirement to do so.

Argon2Iterations: Specifies the number of iterations used for Argon2.

This configuration setting specifies the number of iterations performed for passphrase-based key derivation during symmetric encryption/decryption. Note that this configuration setting is only applicable when UseArgon2 is True and SymmetricPassphrase is specified.

The default value is 3. Valid values range from 1 to 2^(32)-1. Higher values provide more brute-force protection for the key passphrase at the cost of performance. This configuration can be used to tune the running time independently of the memory size (see Argon2MemorySizeExp).

Argon2MemorySizeExp: Specifies the exponent used to calculate the memory size used when creating a key.

This configuration setting specifies the exponent used when calculating the memory size used for passphrase-based key derivation during symmetric encryption/decryption. Note that this configuration setting is only applicable when UseArgon2 is True and SymmetricPassphrase is specified.

The default value is 16. Valid values range from 3 to 31, though the minimum can vary depending on the value of Argon2Parallelism (see below). The memory size (in KB) is calculated as 2^exp, where exp is the value of this configuration setting. For example, the default memory size would be: 2^(16) = 65,536 KB.

Note: The memory size must be an integer number of kilobytes ranging from 8*p to 2^(32)-1, where p is the value of Argon2Parallelism. Therefore, Argon2MemorySizeExp must be an integer ranging from 3+ceil(log2(p)) to 31. For example, if Argon2Parallelism is set to 8, valid values for Argon2MemorySizeExp range from 6 to 31.

Argon2Parallelism: Specifies the degree of parallelism used for Argon2.

This configuration setting specifies the degree of parallelism, or the number of lanes, used for passphrase-based key derivation during symmetric encryption/decryption. Note that this configuration setting is only applicable when UseArgon2 is True and SymmetricPassphrase is specified.

The default value is 4. Valid values range from 1 to 2^(24)-1.

CloseInputStreamAfterProcessing: Determines whether or not the input stream is closed after processing.

Determines whether or not the input stream set by SetInputStream is closed after processing is complete. The default value is True.

CloseOutputStreamAfterProcessing: Determines whether or not the output stream is closed after processing.

Determines whether or not the output stream set by SetOutputStream is closed after processing is complete. The default value is True.

CompressionLevel: The level of compression used.

This setting specifies the level of compression used: possible values depend on the value of CompressionMethod and are detailed below.


zlib	1-6
zip	1-6
bzip2	1-9

Higher values will cause the control to compress better; lower values will cause the control to compress faster. The default value for all methods is 4.

DeleteOutputFileOnError: Whether to delete the output file on an error.

Set this to true to automatically delete any partially written OutputFile if an error occurs. The default is

DetachedSignatureData: The detached signature.

This setting is used to specify the detached signature before calling VerifySignature. The message data should be specified normally and this setting should be set to the detached signature data. Both hex-string and OpenPGP ASCII-armored message formats are allowed. Hex-encoded data should be provided as a string like so:

89011C04000102000605025100459B000A0910E2...

EnsureValidDSASignatureHashAlgorithm: Whether or not to select a suitable signature hash algorithm automatically.

This setting specifies whether the control ensures a valid hash algorithm is selected for use with the loaded DSA or ECDSA key. The default value is True.

DSA Notes

DSA requires that the hash be 160 bits or larger, which means MD5 is not a suitable algorithm. When DSA Signature Hash Algorithm selection is enabled (default) the control will use the preferred algorithm from the key if it meets the requirements for DSA. If the preferred algorithm is MD5 and does not meed the requirements for DSA the control will automatically use a suitable algorithm based on the Q element of the DSA key (may be SHA1, SHA224, or SHA256).

ECDSA Notes

The ECDSA Signature Hash Algorithm requirements are directly related to the KeyCurve used by the key. When this setting is enabled (default) the control will use the preferred algorithm from the key if it meets the requirements for ECDSA. If the preferred algorithm does not meet the requirements the control will automatically select a valid hash algorithm based on the curve as follows:


Curve	Hash Algorithm
secp256r1	SHA256
secp384r1	SHA384
secp521r1	SHA512
secp256k1	SHA256

FileName: The original name of the encrypted file.

When encrypting, this configuration setting can be used to specify the original name of the encrypted data. When specifying an InputFile to encrypt from, this is included automatically in the encrypted packet. After decrypting, this will contain the file name of the original encrypted file.

KeyIdLength: The length of the KeyId available.

This controls the length of KeyId available when RecipientInfo fires. Possible values are 4 or 8 (default).

For OpenPGP v4 keys and earlier, the key Id corresponds to the last 4 or 8 bytes of the key's Fingerprint. For OpenPGP v6 keys, the key Id corresponds to the first 8 bytes of the key's Fingerprint instead. For instance:

5E70662EA810E768

KeySelectionMethod: The method used to select a key for encryption or signing.

When more than one key is present this control can be configured to automatically select a key based on certain criteria (described below) or allow for manual selection.


0	Automatic selection, first suitable subkey. Expired keys accepted.
1	Automatic selection, first suitable subkey. Expired keys not accepted.
2	Automatic selection, newest suitable subkey. Expired keys not accepted (Default).
99	Manual Selection.

A key's suitability is determined by its usage flags.

Manual Selection

To manually select a key for any operation pass the key's Id in the constructor. Openpgp pgp = new Openpgp(); pgp.Config("KeySelectionMethod=99"); pgp.RecipientKeys.Add(new Key(@"C:\path\to\key.asc", "7CA1376C39768977")); // Key with Id 7CA1376C39768977 will be used for encryption.

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.

PGPZipDir: The directory used when creating or extracting a PGP zip file.

A PGP zip file is a Tar archive that is encrypted. It is commonly used by utilities to protect multiple files in one OpenPGP message. The control supports creating and extracting these types of files.

To create a PGP zip file set this value to a location on disk including a filemask and call Encrypt. For instance: OpenPGP1.Config("PGPZipDir=C:\MyFiles\*.txt"); OpenPGP1.OutputFile = "C:\PGPZip.pgp"; OpenPGP1.Encrypt(); The created file returned in the OutputFile property is the PGP zip. If InputFile is specified it is used to temporarily hold the Tar archive while creating the PGP zip file. The temporary file is not automatically deleted. If InputFile is not specified the Tar archive is held in memory while creating the PGP zip file.
To extract a PGP zip file set this value to a location on disk and call Decrypt. For instance: OpenPGP1.Config("PGPZipDir=C:\MyFiles"); OpenPGP1.InputFile = "C:\PGPZip.pgp"; OpenPGP1.Decrypt(); The extracted files will be present in the specified directory. If OutputFile is specified it is used to temporarily hold the Tar archive. The temporary file is not automatically deleted. If OutputFile is not specified the Tar archive is held in memory while extracting the PGP zip file. Note that if the OpenPGP message supplied is not a PGP zip file the decryption will occur as normal without error.

ProgressEventThreshold: The amount of data in bytes to process before firing the progress event.

When encrypting or decrypting, the Progress event is fired as data is processed by the control. When this setting is specified, the event will only fire after processing at least the specified number of bytes. The default value is 0.

PublicKeyringFile: The file name of the public keyring file.

This specifies the name of the public keyring file. The default value is "pubring.gpg". This may be set to a file name only, or a full path including the file name.

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 control will repeatedly fire the Progress event to ask for data. Inside the event set InputMessage 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.

RecursiveDecryptMode: Whether the encrypted data should be decrypted recursively.

In some instances data will be encrypted multiple times. This configuration option determines how the control will handle this situation. Options are:


0	Automatic - If the PGP message contains the special header version "PGP Command Line" then recursive decryption will be attempted. (Default)
1	Always attempt recursive decryption.
2	Never attempt recursive decryption.

RequireEncryption: Whether to throw an error when decrypting and encryption is not detected.

By default, the component's decryption methods will succeed if the message is not encrypted. To cause an error to be thrown in this case, set this option to true.

The default value is false.

RequireIntegrityProtectedPacket: Whether an MDC packet is required for decryption.

When set to true, the control will throw an exception if the message being decrypted does not contain a Message Detection Code (MDC) packet. The default value is false.

RequireSignature: Whether to throw an error when verifying a signature and no signature is found.

By default, the component's signature verification methods will succeed if the message is not signed. To cause an error to be thrown in this case, set this option to true.

The default value is false.

RequireValidSignature: Specifies if an invalid signature is considered an error condition.

By default, if the signature is not valid the control fails with an error. This setting may be set to False to disable this requirement. When False, the Status parameter of the VerificationStatus event should be checked to determine the result of the operation. The default value is True.

SecretKeyringFile: The file name of the secret keyring file.

This specifies the name of the secret keyring file. The default value is "secring.gpg". This may be set to a file name only, or a full path including the file name.

SplitHeaders: Controls whether ASCII Armor headers are split or not.

By default, when headers are specified via MessageHeaders, the control will split headers over a certain length onto multiple lines. This is done to avoid potential errors during transport of the message. If false, the headers will be on one line regardless of length. The default value is True.

SymmetricPassphrase: The password used for symmetric encryption or decryption.

This setting specifies the passphrase when using symmetric encryption. If a value is provided, symmetric encryption/decryption will be attempted. In this case no keys are used for either encryption or decryption. Only Encrypt and Decrypt are valid operations when a value is set. Sign, SignAndEncrypt, VerifySignature, and DecryptAndVerifySignature are not valid operations when using this option.

UseArgon2: Whether to use Argon2 for key derivation during symmetric encryption or decryption.

Determines whether the Argon2 algorithm is used as the String-to-Key (S2K) method for passphrase-based key derivation during symmetric encryption/decryption. The default value is False.

This configuration is only applicable when SymmetricPassphrase is specified and when calling Encrypt or Decrypt. Additionally, the following configuration settings are applicable when this config is set to True:

Argon2Iterations
Argon2Parallelism
Argon2MemorySizeExp

Note that if UseArgon2 is enabled, EncryptingAlgorithm must be specified as an AEAD encryption algorithm (e.g., AES192-OCB). Please see the EncryptingAlgorithm for additional details.

UseMemoryMode: Determines whether the entire message is loaded into memory prior to encryption or decryption.

This config determines whether the entire message is loaded into memory prior to encryption or decryption.

By default, this config is False, and messages will be encrypted or decrypted in a stream-based manner. When True, the entire message will be loaded into memory prior to encryption or decryption.

VerifyClearTextSignatureWithCache: Whether the cleartext message is cached in memory when verifying a cleartext signature.

When verifying a cleartext signature, this configuration setting determines whether the cleartext message is cached in memory.

This config is True by default, and must be true when verifying an OpenPGP v6 cleartext signature. When enabled, the cleartext portion will be cached in memory until the signature is fully processed.

Note: If the signature is known to be an OpenPGP v4 cleartext signature beforehand (i.e., signed with a v4 key), this config may be set to False. However, if this config is disabled, the control will be unable to verify OpenPGP v6 cleartext signatures. In this case, the control will throw an exception when calling VerifySignature or DecryptAndVerifySignature.

VersionHeader: The Version header value in the ASCII armored OpenPGP message.

This setting specifies the Version header value included in the ASCII armored OpenPGP message. This may be set before calling Encrypt, Sign, or SignAndEncrypt. The default value is "IPWorks! OpenPGP 2022".

This setting will be populated after calling Decrypt, VerifySignature, or DecryptAndVerifySignature.

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 control will repeatedly fire the Progress event to provide output data. Inside the event check OutputMessage 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.

MaskSensitiveData: 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 to mask sensitive data. The default is .

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

UseInternalSecurityAPI: Whether or not to use the system security libraries or an internal implementation.

When set to , the control will use the system security libraries by default to perform cryptographic functions where applicable.

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

This setting is set to by default on all platforms.
