Class PKCS5S2ParametersGenerator

  • public class PKCS5S2ParametersGenerator
extends PBEParametersGenerator
    Generator for PBE derived keys and ivs as defined by PKCS 5 V2.0 Scheme 2. This generator uses a SHA-1 HMac as the calculation function.

    The document this implementation is based on can be found at RSA's PKCS5 Page

      • generateDerivedParameters

        public CipherParameters generateDerivedParameters​(int keySize)
        Generate a key parameter derived from the password, salt, and iteration count we are currently initialised with.
        Specified by:
        generateDerivedParameters in class PBEParametersGenerator
        Parameters:
        keySize - the size of the key we want (in bits)
        Returns:
        a KeyParameter object.

      • generateDerivedParameters

        public CipherParameters generateDerivedParameters​(int keySize,
                                                  int ivSize)
        Generate a key with initialisation vector parameter derived from the password, salt, and iteration count we are currently initialised with.
        Specified by:
        generateDerivedParameters in class PBEParametersGenerator
        Parameters:
        keySize - the size of the key we want (in bits)
        ivSize - the size of the iv we want (in bits)
        Returns:
        a ParametersWithIV object.

      • generateDerivedMacParameters

        public CipherParameters generateDerivedMacParameters​(int keySize)
        Generate a key parameter for use with a MAC derived from the password, salt, and iteration count we are currently initialised with.
        Specified by:
        generateDerivedMacParameters in class PBEParametersGenerator
        Parameters:
        keySize - the size of the key we want (in bits)
        Returns:
        a KeyParameter object.
