Class BcCFBSecretKeyEncryptorFactory

java.lang.Object
  org.bouncycastle.openpgp.operator.bc.BcCFBSecretKeyEncryptorFactory

All Implemented Interfaces:

PBESecretKeyEncryptorFactory

public class BcCFBSecretKeyEncryptorFactory

extends java.lang.Object

implements PBESecretKeyEncryptorFactory

Return a factory for PBESecretKeyEncryptor instances which protect the secret key material by deriving a key-encryption-key using S2K.SALTED_AND_ITERATED S2K and apply that key using SecretKeyPacket.USAGE_SHA1 (CFB mode).

This particular factory derives a key-encryption-key via salted+iterated S2K derivation using SHA256 and uses AES256 for secret key protection.
