Constructor Detail

### DESedeParameters

    public DESedeParameters(byte[] key)

Method Detail

### isWeakKey

    public static boolean isWeakKey(byte[] key,
                                    int offset,
                                    int length)

  return true if the passed in key is a DES-EDE weak key.

  Parameters:
    `key` - bytes making up the key
    `offset` - offset into the byte array the key starts at
    `length` - number of bytes making up the key

### isWeakKey

    public static boolean isWeakKey(byte[] key,
                                    int offset)

  return true if the passed in key is a DES-EDE weak key.

  Parameters:
    `key` - bytes making up the key
    `offset` - offset into the byte array the key starts at
  Returns:
    true if the given DES key material is weak or semi-weak, false otherwise.
