Description copied from interface: PGPDataDecryptorFactory

Constructs a data decryptor.

Specified by:

createDataDecryptor in interface PGPDataDecryptorFactory

Parameters:

withIntegrityPacket - true if the packet to be decrypted has integrity checking enabled.

encAlgorithm - the identifier of the encryption algorithm to decrypt with.

key - the bytes of the key for the cipher.

Returns:

a data decryptor that can decrypt (and verify) streams of encrypted data.

Throws:

PGPException - if an error occurs initialising the decryption and integrity checking functions.
