Method Details
-
convertASN1toXMLDSIG
Converts an ASN.1 ECDSA value to a XML Signature ECDSA Value. The JAVA JCE ECDSA Signature algorithm creates ASN.1 encoded (r, s) value pairs; the XML Signature requires the core BigInteger values.- Parameters:
asn1Bytes
-- Returns:
- the decode bytes
- Throws:
IOException
