  • Method Details

    • getUsername

      String getUsername()
      Get the username this Password is associated with.

      Generally a Password should not need to know this information but this is an integral part of how the representation of this Password is created.

      Returns:
      the username this Password is associated with

    • getRealm

      String getRealm()
      Get the realm this Password is associated with.

      Note: This is independent of the name of the realm used to obtain the Password representation, this is the value used to generate the digest.

      Returns:
      the realm this Password is associated with

    • getDigest

      byte[] getDigest()
      Get the digest represented by this Password.
      Returns:
      the digest represented by this Password

    • getParameterSpec

      default DigestPasswordAlgorithmSpec getParameterSpec()
      Description copied from interface: Password
      Get the applicable algorithm parameter specification for this password type.
      Specified by:
      getParameterSpec in interface Password
      Returns:
      the algorithm parameter specification, or null if this password type does not support algorithms

    • impliesParameters

      default boolean impliesParameters(AlgorithmParameterSpec parameterSpec)
      Description copied from interface: Password
      Determine if this password is matched by the given parameter specification.
      Specified by:
      impliesParameters in interface Password
      Parameters:
      parameterSpec - the parameter specification (must not be null)
      Returns:
      true if the password is matched by the parameters, false otherwise

    • clone

      DigestPassword clone()
      Creates and returns a copy of this Password.
      Specified by:
      clone in interface OneWayPassword
      Specified by:
      clone in interface Password
      Returns:
      a copy of this Password.

    • createRaw

      static DigestPassword createRaw(String algorithm, String username, String realm, byte[] digest)
      Create a raw implementation of this password type. No validation of the content is performed, and the password must be "adopted" in to a PasswordFactory (via the PasswordFactory.translate(Password) method) before it can be validated and used to verify guesses.
      Parameters:
      algorithm - the algorithm name
      username - the user name
      realm - the realm
      digest - the digest
      Returns:
      the raw password implementation
