Class BcAEADSecretKeyEncryptorFactory

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

All Implemented Interfaces:

PBESecretKeyEncryptorFactory

public class BcAEADSecretKeyEncryptorFactory

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.ARGON_2 S2K and apply that key using SecretKeyPacket.USAGE_AEAD.

This particular factory uses OCB + AES256 for secret key protection and requires 64MiB of RAM for the Argon2 key derivation (see S2K.Argon2Params#memoryConstrainedParameters()).
