the class DataGenBaseTimeStamp method generatePropertyData.

@Override
public final PropertyDataObject generatePropertyData(TProp prop, PropertiesDataGenerationContext ctx) throws PropertyDataGenerationException {
    Algorithm c14n = this.algsProvider.getCanonicalizationAlgorithmForTimeStampProperties();
    try {
        TimeStampDigestInput digestInput = this.tsInputFactory.newTimeStampDigestInput(c14n);

Example 2 with TimeStampDigestInput

use of xades4j.utils.TimeStampDigestInput in project xades4j by luisgoncalves.

the class TimeStampVerifierBase method verify.
