Class DefaultAlgorithmsProvider

java.lang.Object
  xades4j.providers.impl.DefaultAlgorithmsProvider

All Implemented Interfaces:

AlgorithmsProvider

public class DefaultAlgorithmsProvider
extends Object
implements AlgorithmsProvider

The default implementation of AlgorithmsProvider. The defaults are:

• Signature: RSA(RSA_SHA256), DSA(DSA_SHA1)
• Canonicalization: Canonical XML 1.0 withouth comments
• Digest: SHA256 (data objs and refs properties); SHA1 (time-stamps)
