Constructor Detail

### RSAPSSSignatureRawCodec

    public RSAPSSSignatureRawCodec()

Method Detail

### getFormatID

    public int getFormatID()

  Specified by:
    `getFormatID` in interface `ISignatureCodec`

### encodeSignature

    public byte[] encodeSignature(java.lang.Object signature)

  Returns the encoded form of the designated RSA-PSS signature object according to the Raw format supported by this library.

  The Raw format for an RSA-PSS signature, in this implementation, is a byte sequence consisting of the following:

  1. 4-byte magic consisting of the constant: 0x474E5544,
  3. 1-byte version consisting of the constant: 0x01,
  4. 4-byte count of following bytes representing the RSA-PSS signature bytes in internet order,
  5. the RSA-PSS signature bytes in internet order.
  Specified by:
    `encodeSignature` in interface `ISignatureCodec`
  Parameters:
    `signature` - the signature to encode, consisting of the output of the `sign()` method of a `RSAPSSSignature` instance --a byte array.
  Returns:
    the Raw format encoding of the designated signature.
  Throws:
    `java.lang.IllegalArgumentException` - if the designated signature is not an RSA-PSS one.

### decodeSignature

    public java.lang.Object decodeSignature(byte[] k)

  Specified by:
    `decodeSignature` in interface `ISignatureCodec`
