engineGetURI
public abstract java.lang.String engineGetURI()
Returns the URI representation ofTransformation algorithm
- Specified by:
engineGetURI
in classSignatureAlgorithmSpi
- Returns:
- the URI representation of
Transformation algorithm
-
convertASN1toXMLDSIG
public static byte[] convertASN1toXMLDSIG(byte[] asn1Bytes) throws java.io.IOException
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:
java.io.IOException
- See Also:
- 6.4.1 DSA, 3.3. ECDSA Signatures
-
convertXMLDSIGtoASN1
public static byte[] convertXMLDSIGtoASN1(byte[] xmldsigBytes) throws java.io.IOException
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:
java.io.IOException
- See Also:
- 6.4.1 DSA, 3.3. ECDSA Signatures
