Method Detail

mapDigestAlgoToOID

public org.bouncycastle.asn1.ASN1ObjectIdentifier mapDigestAlgoToOID(HashAlgorithm digestAlgo)

Maps the digest algorithm to corresponding OID value.

timeStamp

public byte[] timeStamp(SignatureInfo signatureInfo,
                        byte[] data,
                        RevocationData revocationData)
                 throws java.lang.Exception

Description copied from interface: TimeStampService

Gives back the encoded time-stamp token for the given array of data bytes. We assume that the time-stamp token itself contains its full certificate chain required for proper validation.

Specified by:

timeStamp in interface TimeStampService

data - the data to be time-stamped.

revocationData - the optional container that needs to be filled up with the revocation data used to validate the TSA certificate chain.

Returns:

the DER encoded time-stamp token.

Throws:

java.lang.Exception - in case something went wrong.
