Package org.gudy.bouncycastle.crypto

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 the Digital Signature Algorithm
Mac The base interface for implementations of message authentication codes (MACs).
StreamCipher the interface stream ciphers conform to.

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 Encyrption (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.
RuntimeCryptoException the foundation class for the exceptions thrown by the crypto packages.
