Interface ISignatureCreationAlgorithm

All Known Subinterfaces:

IMySignature

All Known Implementing Classes:

MyDSASignature, MyECDSASignature, MyRSASignature

public interface ISignatureCreationAlgorithm

This interface represents an algorithm that creates cryptographic signatures.

Method Summary

Modifier and Type	Method and Description
byte[]	encodeForXMLSignature(byte[] a_signature) Encodes a signature in a way it meets the W3C standard for XML signature values.
mybouncycastle.org.bouncycastle.asn1.x509.AlgorithmIdentifier	getIdentifier() Returns the algorithm identifier.
java.lang.String	getXMLSignatureAlgorithmReference() Returns a description of the the signature algorithm for XML signatures as defined in http://www.w3.org/TR/xmldsig-core/#sec-AlgID.
byte[]	sign(byte[] a_message) Signs a message and returns the signature.

Method Detail

sign

byte[] sign(byte[] a_message)

Signs a message and returns the signature.

Parameters:

a_message - a message

Returns:

the signature that was created

encodeForXMLSignature

byte[] encodeForXMLSignature(byte[] a_signature)

Encodes a signature in a way it meets the W3C standard for XML signature values. Without this encoding, RSA XML signatures cannot be created.

Parameters:

a_signature - an non-encoded signature

Returns:

the encoded signature or null if an error occured

getIdentifier

mybouncycastle.org.bouncycastle.asn1.x509.AlgorithmIdentifier getIdentifier()

Returns the algorithm identifier.

Returns:

the algorithm identifier

getXMLSignatureAlgorithmReference

java.lang.String getXMLSignatureAlgorithmReference()

Returns a description of the the signature algorithm for XML signatures as defined in http://www.w3.org/TR/xmldsig-core/#sec-AlgID. This description is optional, documents may be signed without it.

Returns:

a description of the the signature algorithm for XML signatures
