Method Detail

getSignatureTimestamps

public static Collection getSignatureTimestamps(SignerInformation signerInfo,
                                                Provider provider)
                                         throws TSPValidationException

Deprecated. use getSignatureTimestamps(SignerInformation, DigestCalculatorProvider)

Fetches the signature time-stamp attributes from a SignerInformation object. Checks that the MessageImprint for each time-stamp matches the signature field. (see RFC 3161 Appendix A).

Parameters:

signerInfo - a SignerInformation to search for time-stamps

provider - an optional provider to use to create MessageDigest instances

Returns:

a collection of TimeStampToken objects

Throws:

TSPValidationException

getSignatureTimestamps

public static Collection getSignatureTimestamps(SignerInformation signerInfo,
                                                DigestCalculatorProvider digCalcProvider)
                                         throws TSPValidationException

Fetches the signature time-stamp attributes from a SignerInformation object. Checks that the MessageImprint for each time-stamp matches the signature field. (see RFC 3161 Appendix A).

Parameters:

signerInfo - a SignerInformation to search for time-stamps

digCalcProvider - provider for digest calculators

Returns:

a collection of TimeStampToken objects

Throws:

TSPValidationException

validateCertificate

public static void validateCertificate(X509Certificate cert)
                                throws TSPValidationException

Validate the passed in certificate as being of the correct type to be used for time stamping. To be valid it must have an ExtendedKeyUsage extension which has a key purpose identifier of id-kp-timeStamping.

Parameters:

cert - the certificate of interest.

Throws:

TSPValidationException - if the certicate fails on one of the check points.

validateCertificate

public static void validateCertificate(X509CertificateHolder cert)
                                throws TSPValidationException

Validate the passed in certificate as being of the correct type to be used for time stamping. To be valid it must have an ExtendedKeyUsage extension which has a key purpose identifier of id-kp-timeStamping.

Parameters:

cert - the certificate of interest.

Throws:

TSPValidationException - if the certicate fails on one of the check points.
