OpenPGP Component

Properties Methods Events Config Settings Errors

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

Syntax

TipgOpenPGP

Remarks

The OpenPGP component supports encrypting/decrypting and signing/verifying OpenPGP messages in the format specified by RFC 4880.

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 Key* properties specify the key (with private key) used to sign and decrypt.

The SignerKey* properties specify the key used to verify a signature.

The RecipientKey* properties specify the key used to encrypt.

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:

SetInputStream
InputFile
InputMessage

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

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

When using streams you may need to additionally set CloseInputStreamAfterProcessing or CloseOutputStreamAfterProcessing.

Syntax

function Config(ConfigurationString: String): String;

Remarks

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

These 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.

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 Component)

Decrypts the message.

Syntax

procedure Decrypt();

Remarks

This method decrypts the specified message.

The message will be decrypted using the keys specified in the Key* properties. Before decryption begins the component will fire the RecipientInfo event with information about the encrypted message, including the key used to encrypt the message. Within this event you may use the available information to load the correct key into Keys.

DecryptAndVerifySignature Method (OpenPGP Component)

Decrypts and verifies the signature of the message.

Syntax

procedure 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 component will perform the decryption without error.

The message will be verified using the keys specified in the SignerKey* properties. Before verification begins the component 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 the SignerKey* properties.

By default, if the signature is not valid the component raises an exception. 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 Component)

Encrypt and/or Sign

You can call this method to set the input stream that you would like to sign and/or encrypt. Then call Sign, Encrypt, or SignAndEncrypt to sign and/or encrypt the message. The appropriate ASCII Armor headers will be generated in MessageHeaders.

Decrypt and/or Verify

You can call this method to specify a valid input stream that contains the signed and/or encrypted data you would like to verify or decrypt. Then call VerifySignature, Decrypt, or DecryptAndVerifySignature to verify and/or decrypt the message.

The content of the stream will be read from the current position all the way to the end and no bytes will be skipped.

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:

SetInputStream
InputFile
InputMessage

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

When using streams you may need to additionally set CloseInputStreamAfterProcessing or CloseOutputStreamAfterProcessing.

SetOutputStream Method (OpenPGP Component)

The stream to which the component will write the fully encrypted or decrypted OpenPGP data.

Syntax

procedure SetOutputStream(OutputStream: TStream);

Remarks

This method sets the stream to which the component will write the fully encrypted or decrypted OpenPGP data. If an output stream is set before the component attempts to encode or decode an OpenPGP message, the component will write the data to the output stream instead of populating OutputMessage or writing to OutputFile.

Sign and/or Encrypt

To sign and/or encrypt a message to an output stream, you must first populate the Message property with the data you would like to sign and/or encrypt. Next, this method must be called with a valid output stream for which the component may write the signed or encrypted data. Then call Sign, Encrypt, or SignAndEncrypt to sign and/or encrypt the message. The appropriate ASCII Armor headers will be generated in MessageHeaders.

Decrypt and/or Verify

If you would like to decrypt a message or verify its signature and write the resulting message to an output stream, you should set the Message property to the signed and/or encrypted message you would like to verify or decrypt. Next, you must call this method to specify a valid stream for the component to write the data to. Then call VerifySignature, Decrypt, or DecryptAndVerifySignature to verify and/or decrypt the message.

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:

SetInputStream
InputFile
InputMessage

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

When This property is set the component will read the keyring and populate the Key* properties with the first key found in the keyring. Set UserId to select a different key in the current keyring.

OtherUserIds
String (read-only)
Default Value: ""

If the specified key has alternate user Ids associated with it, this property returns a comma-separated list of the other user Ids.

Passphrase
String
Default Value: ""

The passphrase for the key's secret key (if any). This must be specified before operations requiring the secret key are attempted. The passphrase may be supplied in this property or through the KeyPassphrase event, which will fire when a passphrase is required.

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

AddUserId
SignUserId
ChangeExpirationDate
ChangePassphrase

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

Decrypt
Sign
SignAndEncrypt

PublicKey
String (read-only)
Default Value: ""

The public key of the key. The key is provided as ASCII armored data.

PublicKeyAlgorithm
String (read-only)
Default Value: ""

A text description of the public key algorithm of the key. Possible values are:

RSA
DSA
ECDSA
EdDSA
RSA-Legacy

PublicKeyLength
Integer (read-only)
Default Value: 0

The length of the public key in bits. Common values are 512, 1024, and 2048.

If the PublicKeyAlgorithm property is ECDSA or EcDSA the length of the public key is determined by the Curve. Possible lenghts are:


Curve	Public Key Length (bits)
secp256r1	256
secp384r1	384
secp521r1	521
Ed25519	256
secp256k1	256

Revoked
Boolean (read-only)
Default Value: False

Whether or not the key is revoked.

SecretKey
String (read-only)
Default Value: ""

The secret key of the key (if available). The key is provided as ASCII armored data.

SecretKeyAvailable
Boolean (read-only)
Default Value: False

Whether or not a secret key is available for the selected key.

Usage
String (read-only)
Default Value: ""

A text description of UsageFlags.

The value will be of one or more of the following strings, separated by commas:

Certifying Other Certificates
Signing Emails and Files
Encrypting Emails and Files
Split Key
Authenticate Against Servers
Group Key

UsageFlags
Integer (read-only)
Default Value: 47

Flags that show the intended use for the key. The default value is 0x0F. The value of UsageFlags is a combination of the following flags:


0x01	This key may be used to certify other keys.
0x02	This key may be used to sign data.
0x0C	This key may be used to encrypt communications and encrypt storage.
0x10	The private component of this key may have been split by a secret-sharing mechanism.
0x20	This key may be used for authentication.
0x80	The private component of this key may be in the possession of more than one person.

Please refer to the Usage property for a text representation of UsageFlags.

UserId
String
Default Value: ""

The user Id of the key. When a key is loaded this property is populated with the user Id associated with the key. This property may be set to load a key from the Keyring. When this property is set the component will search the Keyring for a key associated with the UserId specified.

When loading a key with multiple user Ids, this property will be populated with the UserId that was most recently added to the key. To discover all of the UserIds associated with a key query this property and OtherUserIds after loading the key.

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.

When using this property to select a key you may also specify the key's Id, or any of its subkeys' Ids, instead of a user Id. The component will then search for a key with a matching Id. This is helpful in situations where you do not have the UserId but still need to load the key, such as within the OpenPGP component's RecipientInfo event.

Config Settings (OpenPGP 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.

OpenPGP Config Settings

AllowEmptyInput: Whether to allow empty files for input.

This setting controls whether the component allows empty input when processing. When True, the component 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 component 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 component 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.

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 component to compress better; lower values will cause the component 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 False

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 component 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 component 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 component 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 Curve used by the key. When this setting is enabled (default) the component 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 component 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 (default) or 8.

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

When more than one key is present this component 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 component 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 component. 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 component 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 component 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 component 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 component raises an exception. 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 component 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.

UseFipsCompliantAlgorithms: Restricts the usage to FIPS compliant algorithms only.

When enabled the component will only support FIPS compliant algorithms. If a non-FIPS compliant algorithm is used an exception is thrown. The following algorithms are supported when this setting is True:

3DES
AES128
AES192
AES256
RSA
DSA
SHA1
SHA256
SHA384
SHA512
SHA224

The default value is False.

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 component 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.

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.

CodePage: The system code page used for Unicode to Multibyte translations.

The default code page is Unicode UTF-8 (65001).

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 True.

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: 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.

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

This setting is set to False by default on all platforms.
