Method Detail

convertASN1toXMLDSIG

public static byte[] convertASN1toXMLDSIG(byte[] asn1Bytes)
                                   throws 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:

IOException

6.4.1 DSA, 3.3. ECDSA Signatures

convertXMLDSIGtoASN1

public static byte[] convertXMLDSIGtoASN1(byte[] xmldsigBytes)
                                   throws 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:

IOException
