# Package org.bouncycastle.jcajce.spec

- Class Summary
  Class | Description
  --- | ---
  AEADParameterSpec | ParameterSpec for AEAD modes which allows associated data to be added via an algorithm parameter spec.In normal circumstances you would only want to use this if you had to work with the pre-JDK1.7 Cipher class as associated data is ignored for the purposes of returning a Cipher's parameters.
  CompositeAlgorithmSpec |
  CompositeAlgorithmSpec.Builder |
  DHDomainParameterSpec | Extension class for DHParameterSpec that wraps a DHDomainParameters object and provides the q domain parameter.
  DHExtendedPrivateKeySpec | A DHPrivateKeySpec that also carries a set of DH domain parameters.
  DHExtendedPublicKeySpec | A DHPublicKeySpec that also carries a set of DH domain parameters.
  DHUParameterSpec | Parameter spec to provide Diffie-Hellman Unified model keys and user keying material.
  DSTU4145ParameterSpec | ParameterSpec for a DSTU4145 key.
  EdDSAParameterSpec | ParameterSpec for EdDSA signature algorithms.
  GOST28147ParameterSpec | A parameter spec for the GOST-28147 cipher.
  GOST28147WrapParameterSpec | A parameter spec for the GOST-28147 cipher.
  GOST3410ParameterSpec | ParameterSpec for a GOST 3410-1994/2001/2012 algorithm parameters.
  KTSParameterSpec | Parameter spec for doing KTS based wrapping via the Cipher API.
  KTSParameterSpec.Builder | Builder class for creating a KTSParameterSpec.
  MQVParameterSpec | Parameter spec to provide MQV ephemeral keys and user keying material.
  OpenSSHPrivateKeySpec | OpenSSHPrivateKeySpec holds and encoded OpenSSH private key.
  OpenSSHPublicKeySpec | Holds an OpenSSH encoded public key.
  PBKDF2KeySpec | Extension of PBEKeySpec which takes into account the PRF algorithm setting available in PKCS#5 PBKDF2.
  RepeatedSecretKeySpec | A simple object to indicate that a symmetric cipher should reuse the last key provided.
  ScryptKeySpec | Key spec for use with the scrypt SecretKeyFactory.
  SkeinParameterSpec | Parameters for the Skein hash function - a series of byte[] strings identified by integer tags.
  SkeinParameterSpec.Builder | A builder for `SkeinParameterSpec`.
  SM2ParameterSpec | Parameter spec for SM2 ID parameter
  TLSKeyMaterialSpec | Key Spec class for generating TLS key/iv material.
  UserKeyingMaterialSpec |
  XDHParameterSpec | ParameterSpec for XDH key agreement algorithms.
