encodeSignature
public byte[] encodeSignature(Object signature)
Returns the encoded form of the designated DSS (Digital Signature Standard)
signature object according to the
Raw format supported by this
library.
The
Raw format for a DSA 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_DSS_SIGNATURE, - 1-byte version consisting of the constant: 0x01,
- 4-byte count of following bytes representing the DSS parameter
r in internet order, - n-bytes representation of a
BigInteger obtained by invoking
the toByteArray() method on the DSS parameter r,
- 4-byte count of following bytes representing the DSS parameter
s, - n-bytes representation of a
BigInteger obtained by invoking
the toByteArray() method on the DSS parameter s.
- encodeSignature in interface ISignatureCodec
signature - the signature to encode, consisting of the two DSS
parameters r and s as a
BigInteger array.
- the Raw format encoding of the designated signature.
