Method Detail

convertASN1toXMLDSIG

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

Converts an ASN.1 DSA value to a XML Signature DSA Value.

The JAVA JCE DSA Signature algorithm creates ASN.1 encoded (r,s) value pairs; the XML Signature requires the core BigInteger values.

Parameters:

asn1Bytes -

Throws:

IOException

convertXMLDSIGtoASN1

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

Converts a XML Signature DSA Value to an ASN.1 DSA value.

The JAVA JCE DSA Signature algorithm creates ASN.1 encoded (r,s) value pairs; the XML Signature requires the core BigInteger values.

Parameters:

xmldsigBytes -

Throws:

IOException
