Method Detail

• setProvider

  public JcePKCSPBEOutputEncryptorBuilder setProvider​(java.security.Provider provider)

• setProvider

  public JcePKCSPBEOutputEncryptorBuilder setProvider​(java.lang.String providerName)

• setRandom

  public JcePKCSPBEOutputEncryptorBuilder setRandom​(java.security.SecureRandom random)

• setKeySizeProvider

  public JcePKCSPBEOutputEncryptorBuilder setKeySizeProvider​(SecretKeySizeProvider keySizeProvider)

  Set the lookup provider of AlgorithmIdentifier returning key_size_in_bits used to handle PKCS5 decryption.

  Parameters:

  keySizeProvider - a provider of integer secret key sizes.

  Returns:

  the current builder.

• setPRF

  public JcePKCSPBEOutputEncryptorBuilder setPRF​(org.bouncycastle.asn1.x509.AlgorithmIdentifier prf)

  public JcePKCSPBEOutputEncryptorBuilder setIterationCount​(int iterationCount)

  Set the iteration count for the PBE calculation.

  Parameters:

  iterationCount - the iteration count to apply to the key creation.

  Returns:

  the current builder.

  Throws:

  java.lang.IllegalStateException - if this builder was intialised with a PBKDFDef

• build

  public OutputEncryptor build​(char[] password)
                        throws OperatorCreationException

  Throws:

  OperatorCreationException
