Method Details

decodeSignature

public Object decodeSignature(byte[] k)
Specified by:
decodeSignature in interface ISignatureCodec

encodeSignature

public byte[] encodeSignature(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 value of the literal Registry.MAGIC_RAW_RSA_PSS_SIGNATURE,
  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:
IllegalArgumentException - if the designated signature is not an RSA-PSS one.

getFormatID

public int getFormatID()
Specified by:
getFormatID in interface ISignatureCodec
