primaryKey - primary key

id - id to associate with the key.

checksumCalculator - key checksum calculator

hashedPcks - hashed signature subpackets

unhashedPcks - unhashed signature subpackets

keySignerBuilder - builder for key certifications - will be initialised with primary secret key.

keyEncryptor - encryptor for secret subkeys.

Throws:

PGPException - error during signature generation

                           PGPDigestCalculator checksumCalculator,
                           PGPSignatureSubpacketVector hashedPcks,

                    throws PGPException

Create a new key ring generator without a user-id, but instead with a primary key carrying a direct-key signature.

Parameters:

primaryKey - primary key

checksumCalculator - checksum calculator

hashedPcks - hashed signature subpackets

unhashedPcks - unhashed signature subpackets

keySignerBuilder - signer builder

keyEncryptor - key encryptor

Throws:

PGPException - error during signature generation

PGPKeyRingGenerator

public PGPKeyRingGenerator(PGPSecretKeyRing originalSecretRing,
                           PBESecretKeyDecryptor secretKeyDecryptor,
                           PGPDigestCalculator checksumCalculator,

                           PBESecretKeyEncryptor keyEncryptor)
                    throws PGPException

Create a new key ring generator based on an original secret key ring. The default hashed/unhashed sub-packets for subkey signatures will be inherited from the first signature on the primary key (other than CREATION-TIME which will be ignored).

Parameters:

originalSecretRing - the secret key ring we want to add a subkeyto,

secretKeyDecryptor - a decryptor for the signing primary key.

checksumCalculator - key checksum calculator

keySignerBuilder - builder for key certifications - will be initialised with primary secret key.

keyEncryptor - encryptor for secret subkeys.

Throws:

PGPException - error during signature generation

Method Detail

addSubKey

public void addSubKey(PGPKeyPair keyPair)
               throws PGPException

Add a sub key to the key ring to be generated with default certification and inheriting the hashed/unhashed packets of the primary key.

Parameters:

keyPair - the key pair to add.

Throws:

PGPException - error during signature generation

addSubKey

public void addSubKey(PGPKeyPair keyPair,
                      PGPContentSignerBuilder bindingSignerBldr)
               throws PGPException

Add a sub key to the key ring to be generated with default certification and inheriting the hashed/unhashed packets of the primary key. If bindingSignerBldr is not null it will be used to add a Primary Key Binding signature (type 0x19) into the hashedPcks for the key (required for signing subkeys).

Parameters:

keyPair - the key pair to add.

bindingSignerBldr - provide a signing builder to create the Primary Key signature.

Throws:

PGPException - error during signature generation

addSubKey

public void addSubKey(PGPKeyPair keyPair,
                      PGPSignatureSubpacketVector hashedPcks,
                      PGPSignatureSubpacketVector unhashedPcks)
               throws PGPException

Add a subkey with specific hashed and unhashed packets associated with it and default certification.

Parameters:

keyPair - public/private key pair.

hashedPcks - hashed packet values to be included in certification.

unhashedPcks - unhashed packets values to be included in certification.

Throws:

PGPException - error during signature generation

addSubKey

public void addSubKey(PGPKeyPair keyPair,
                      PGPSignatureSubpacketVector hashedPcks,
                      PGPSignatureSubpacketVector unhashedPcks,
                      PGPContentSignerBuilder bindingSignerBldr)
               throws PGPException

Add a subkey with specific hashed and unhashed packets associated with it and default certification. If bindingSignerBldr is not null it will be used to add a Primary Key Binding signature (type 0x19) into the hashedPcks for the key (required for signing subkeys).

Parameters:

keyPair - public/private key pair.

hashedPcks - hashed packet values to be included in certification.

unhashedPcks - unhashed packets values to be included in certification.

bindingSignerBldr - provide a signing builder to create the Primary Key signature.
