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 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:

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
