OpenPGP Class

Properties   Methods   Events   Config Settings   Errors  

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

Syntax

ipworksopenpgp.OpenPGP

Remarks

The OpenPGP class 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 class 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

public String config(String configurationString);

Remarks

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

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, 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 Class)

Decrypts the message.

Syntax

public void decrypt();

Remarks

This method decrypts the specified message.

The message will be decrypted using the keys specified in Keys. Before decryption begins the class 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 Class)

Decrypts and verifies the signature of the message.

Syntax

public void 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 class will perform the decryption without error.

The message will be decrypted using the keys specified in Keys. Before decryption begins the class 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.

The message will be verified using the keys specified in SignerKeys. Before verification begins the class 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 class throws 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 Class)

Encrypts the message.

Syntax

public void encrypt();

Remarks

This method encrypts the specified message.

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

Remarks

This method resets all message and key properties to their default values.

SetInputStream Method (OpenPGP Class)

Sets the stream from which the class will read data to encrypt or decrypt.

Syntax

public void setInputStream(java.io.InputStream inputStream);

Remarks

This method sets the stream from which the class will read data to encrypt or decrypt. If an input stream is set before the class attempts to encode or decode an OpenPGP message, the data is read from the input stream instead of from the InputFile or InputMessage properties.

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 class 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.

SetOutputStream Method (OpenPGP Class)

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

Syntax

public void setOutputStream(java.io.OutputStream outputStream);

Remarks

This method sets the stream to which the class will write the fully encrypted or decrypted OpenPGP data. If an output stream is set before the class attempts to encode or decode an OpenPGP message, the class 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 class 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 class 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.

Sign Method (OpenPGP Class)

When signing, the following properties may be used to further configure the class:

• ASCIIArmor
• ClearSignature
• DetachedSignature
• SigningAlgorithm

VerifySignature Method (OpenPGP Class)

Verifies the signature of the current message.

Syntax

public void verifySignature();

Remarks

This method verifies the signature of the message.

The message will be verified using the keys specified in SignerKeys. Before verification begins the class 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 class throws 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.

Error Event (OpenPGP Class)

Fired when information is available about errors during data delivery.

Syntax

public class DefaultOpenPGPEventListener implements OpenPGPEventListener {
  ...
  public void error(OpenPGPErrorEvent e) {}
  ...
}

public class OpenPGPErrorEvent {
  public int errorCode;
  public String description;
}

Remarks

The Error event is fired in case of exceptional conditions during message processing. Normally the class throws an exception.

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 Class)

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

Syntax

public class DefaultOpenPGPEventListener implements OpenPGPEventListener {
  ...
  public void keyPassphrase(OpenPGPKeyPassphraseEvent e) {}
  ...
}

public class OpenPGPKeyPassphraseEvent {
  public String userId;
  public String keyId;
  public String fingerprint;
  public String passphrase; //read-write
}

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 Passphrase field before attempting the operation.

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

• AddUserId
• SignUserId
• ChangeExpirationDate
• ChangePassphrase

When using the OpenPGP class, or an email-based class, 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>

Note that for OpenPGP v6, a key may be created with or without a UserId, as the field is optional. If a key was created without a UserId, the key's Fingerprint can be used as it's identifier instead.

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 Class)

Fired as progress is made.

Syntax

public class DefaultOpenPGPEventListener implements OpenPGPEventListener {
  ...
  public void progress(OpenPGPProgressEvent e) {}
  ...
}

public class OpenPGPProgressEvent {
  public long bytesProcessed;
  public int percentProcessed;
  public int operation;
  public boolean isEOF; //read-write
}

Remarks

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

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:

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 class. When the Operation is Write (2) this value may be queried to determine when all data has been processed.

RecipientInfo Event (OpenPGP Class)

Fired for each recipient key of the encrypted message.

Syntax

public class DefaultOpenPGPEventListener implements OpenPGPEventListener {
  ...
  public void recipientInfo(OpenPGPRecipientInfoEvent e) {}
  ...
}

public class OpenPGPRecipientInfoEvent {
  public String keyId;
  public String fingerprint;
  public String publicKeyAlgorithm;
}

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 Keys. Keys 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)

  public String publicKeyAlgorithm;
}

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 SignerKeys. SignerKeys 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
