Class Overview

support class for constructing intergrated encryption ciphers for doing basic message exchanges on top of key agreement ciphers

Public Constructors
	IESEngine(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.
	IESEngine(BasicAgreement agree, DerivationFunction kdf, Mac mac, BufferedBlockCipher cipher) set up for use in conjunction with a block cipher to handle the message.

Public Methods
void	init(boolean forEncryption, CipherParameters privParam, CipherParameters pubParam, CipherParameters param) Initialise the encryptor.
byte[]	processBlock(byte[] in, int inOff, int inLen)

Inherited Methods

From class java.lang.Object

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.

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

set up for use in conjunction with a block cipher to handle the message.

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

Initialise the encryptor.

forEncryption	whether or not this is encryption/decryption.
privParam	our private key parameters
pubParam	the recipient's/sender's public key parameters
param	encoding and derivation parameters.
