public byte[] encodeSignature(java.lang.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:
Registry.MAGIC_RAW_DSS_SIGNATURE
,r
in internet order,BigInteger
obtained by invoking
the toByteArray()
method on the DSS parameter r
,s
,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.java.lang.IllegalArgumentException
- if the designated signature is not a
DSS (Digital Signature Standard) one.public java.lang.Object decodeSignature(byte[] k)
