Class OldIESEngine


  • public class OldIESEngine
    extends IESEngine
    Support class for constructing integrated encryption ciphers for doing basic message exchanges on top of key agreement ciphers. Follows the description given in IEEE Std 1363a.

        public OldIESEngine​(BasicAgreement agree,
                            DerivationFunction kdf,
                            Mac mac)
        set up for use with stream mode, where the key derivation function is used to provide a stream of bytes to xor with the message.
        Parameters:
        agree - the key agreement used as the basis for the encryption
        kdf - the key derivation function used for byte generation
        mac - the message authentication code generator for the message

        public OldIESEngine​(BasicAgreement agree,
                            DerivationFunction kdf,

                            BufferedBlockCipher cipher)
        set up for use in conjunction with a block cipher to handle the message.
        Parameters:
        agree - the key agreement used as the basis for the encryption
        kdf - the key derivation function used for byte generation
        mac - the message authentication code generator for the message
        cipher - the cipher to used for encrypting the message
