engineGetURI
Returns the URI representation ofTransformation algorithm
- Specified by:
engineGetURI
in classSignatureAlgorithmSpi
- Returns:

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
- See Also:
-
convertXMLDSIGtoASN1
Converts a XML Signature ECDSA Value to an ASN.1 DSA value. The JAVA JCE ECDSA Signature algorithm creates ASN.1 encoded (r, s) value pairs; the XML Signature requires the core BigInteger values.- Parameters:
xmldsigBytes
-- Returns:
- the encoded ASN.1 bytes
- Throws:
IOException
- See Also:
