RSAPSSSignatureRawCodec
public RSAPSSSignatureRawCodec()
getFormatID
public int getFormatID()
- Specified by:
getFormatID
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:
- 4-byte magic consisting of the value of the literal
Registry.MAGIC_RAW_RSA_PSS_SIGNATURE
, -
- 1-byte version consisting of the constant: 0x01,
- 4-byte count of following bytes representing the RSA-PSS signature
bytes in internet order,
- 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.
decodeSignature
public Object decodeSignature(byte[] k)
- Specified by:
decodeSignature
in interface ISignatureCodec
