Method Detail

createDataDecryptor

PGPDataDecryptor createDataDecryptor(boolean withIntegrityPacket,
                                     int encAlgorithm,
                                     byte[] key)
                              throws PGPException

Constructs a data decryptor.

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.

createDataDecryptor

PGPDataDecryptor createDataDecryptor(int aeadAlgorithm,
                                     byte[] iv,
                                     int chunkSize,
                                     int encAlgorithm,
                                     byte[] key)
                              throws PGPException

Constructs an AEAD data decryptor.

Parameters:

aeadAlgorithm - the identifier of the encryption algorithm to use.

iv - the initialization vector to build the AEAD nonces from.

chunkSize - the chunksize value for the AEAD encrypted chunks.

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.
