ArxanIESEngine

public ArxanIESEngine(org.spongycastle.crypto.BasicAgreement agree,
                      org.spongycastle.crypto.DerivationFunction kdf,
                      org.spongycastle.crypto.Mac mac,
                      org.spongycastle.crypto.Digest hash,
                      org.spongycastle.crypto.BufferedBlockCipher cipher)

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.

参数:

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

hash - hash ing function

cipher - the actual cipher
