Description

Interface Summary
AsymmetricBlockCipher: base interface that a public/private key block cipher needs to conform to.
AsymmetricCipherKeyPairGenerator: interface that a public/private key pair generator should conform to.
BasicAgreement: The basic interface that basic Diffie-Hellman implementations conforms to.
BlockCipher: Block cipher engines are expected to conform to this interface.
CipherParameters: all parameter classes implement this.
DerivationFunction: base interface for general purpose byte derivation functions.
DerivationParameters: Parameters for key/byte stream derivation classes
Digest: interface that a message digest conforms to.
DSA: interface for classes implementing algorithms modeled similar to the Digital Signature Alorithm.
ExtendedDigest
Mac: The base interface for implementations of message authentication codes (MACs).
Signer: Generic signer interface for hash based and message recovery signers.
SignerWithRecovery: Signer with message recovery.
StreamCipher: the interface stream ciphers conform to.
Wrapper

Class Summary
AsymmetricCipherKeyPair: a holding class for public/private parameter pairs.
BufferedAsymmetricBlockCipher: a buffer wrapper for an asymmetric block cipher, allowing input to be accumulated in a piecemeal fashion until final processing.
BufferedBlockCipher: A wrapper class that allows block ciphers to be used to process data in a piecemeal fashion.
CipherKeyGenerator: The base class for symmetric, or secret, cipher key generators.
KeyGenerationParameters: The base class for parameters to key generators.
PBEParametersGenerator: super class for all Password Based Encryption (PBE) parameter generator classes.
StreamBlockCipher: a wrapper for block ciphers with a single byte block size, so that they can be treated like stream ciphers.

Exception Summary
CryptoException: the foundation class for the hard exceptions thrown by the crypto packages.
DataLengthException: this exception is thrown if a buffer that is meant to have output copied into it turns out to be too short, or if we've been given insufficient input.
InvalidCipherTextException: this exception is thrown whenever we find something we don't expect in a message.
MaxBytesExceededException: this exception is thrown whenever a cipher requires a change of key, iv or similar after x amount of bytes enciphered
RuntimeCryptoException: the foundation class for the exceptions thrown by the crypto packages.
