- Class Summary
  Class | Description
  --- | ---
  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.
  Commitment | General holding class for a commitment.
  EphemeralKeyPair |
  KeyGenerationParameters | The base class for parameters to key generators.
  PBEParametersGenerator | super class for all Password Based Encryption (PBE) parameter generator classes.
  StreamBlockCipher | A parent class for block cipher modes that do not require block aligned data to be processed, but can function in a streaming mode.

- Exception Summary
  Exception | Description
  --- | ---
  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
  OutputLengthException |
  RuntimeCryptoException | the foundation class for the exceptions thrown by the crypto packages.
