Method Detail

recoverSessionData

byte[] recoverSessionData(PublicKeyEncSessionPacket pkesk,
                          InputStreamPacket encData)
                   throws PGPException

Recover the plain session info by decrypting the encrypted session key. The session info ALWAYS has the symmetric algorithm ID prefixed, so the return value is:

[sym-alg][session-key][checksum]?

Parameters:

pkesk - public-key encrypted session-key packet

encData - encrypted data (sed/seipd/oed) packet

Returns:

decrypted session info

Throws:

PGPException

recoverSessionData

byte[] recoverSessionData(int keyAlgorithm,
                          byte[][] secKeyData)
                   throws PGPException

Deprecated.

use recoverSessionData(PublicKeyEncSessionPacket, InputStreamPacket) instead.

Recover the plain session info by decrypting the encrypted session key. This method returns the decrypted session info as-is (without prefixing missing cipher algorithm), so the return value is:

[sym-alg]?[session-key][checksum]?

Parameters:

keyAlgorithm - public key algorithm

secKeyData - encrypted session key data

Returns:

decrypted session info

Throws:

PGPException

recoverSessionData

byte[] recoverSessionData(int keyAlgorithm,
                          byte[][] secKeyData,
                          int pkeskVersion)
                   throws PGPException

Deprecated.

use recoverSessionData(PublicKeyEncSessionPacket, InputStreamPacket) instead.

Recover the plain session info by decrypting the encrypted session key. This method returns the decrypted session info as-is (without prefixing missing cipher algorithm), so the return value is:

[sym-alg]?[session-key][checksum]?

Parameters:

keyAlgorithm - public key algorithm

secKeyData - encrypted session key data

pkeskVersion - version of the PKESK packet

Returns:

decrypted session info

Throws:

PGPException
