Class SVTAlgoRegistry

java.lang.Object
se.swedenconnect.sigval.svt.algorithms.SVTAlgoRegistry
public class SVTAlgoRegistry extends Object
Registry for SVT supported algorithms. This class adds support for the minimum supported set of algorithms and allows new algorithms to be added. By default only RSA and ECDSA with SHA 245, 384 and 512 are supported.
