Doc from org.bouncycastle.openpgp.operator.PublicKeyDataDecryptorFactory.recoverSessionData.

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:PublicKeyEncSessionPacket

public-key encrypted session-key packet

encData:InputStreamPacket

encrypted data (sed/seipd/oed) packet

Returns:byte[]

decrypted session info

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

Implements org.bouncycastle.openpgp.operator.PublicKeyDataDecryptorFactory.recoverSessionData.

Doc from org.bouncycastle.openpgp.operator.PublicKeyDataDecryptorFactory.recoverSessionData.

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:int

public key algorithm

secKeyData:byte[][]

encrypted session key data

Returns:byte[]

decrypted session info
