                     CertificateNotYetValidException,
                     NoSuchProviderException

Deprecated.

Validate the time stamp token.

To be valid the token must be signed by the passed in certificate and the certificate must be the one referred to by the SigningCertificate attribute included in the hashed attributes of the token. The certificate must also have the ExtendedKeyUsageExtension with only KeyPurposeId.id_kp_timeStamping and have been valid at the time the timestamp was created.

A successful call to validate means all the above are true.

Throws:

TSPException

TSPValidationException

CertificateExpiredException

CertificateNotYetValidException

NoSuchProviderException

validate

public void validate(SignerInformationVerifier sigVerifier)
              throws TSPException,
                     TSPValidationException

Validate the time stamp token.

To be valid the token must be signed by the passed in certificate and the certificate must be the one referred to by the SigningCertificate attribute included in the hashed attributes of the token. The certificate must also have the ExtendedKeyUsageExtension with only KeyPurposeId.id_kp_timeStamping and have been valid at the time the timestamp was created.

A successful call to validate means all the above are true.

Parameters:

sigVerifier - the content verifier create the objects required to verify the CMS object in the timestamp.

Throws:

TSPException - if an exception occurs in processing the token.

TSPValidationException - if the certificate or signature fail to be valid.

IllegalArgumentException - if the sigVerifierProvider has no associated certificate.

isSignatureValid

public boolean isSignatureValid(SignerInformationVerifier sigVerifier)
                         throws TSPException

Return true if the signature on time stamp token is valid.

Note: this is a much weaker proof of correctness than calling validate().

Parameters:

sigVerifier - the content verifier create the objects required to verify the CMS object in the timestamp.

Returns:

true if the signature matches, false otherwise.

Throws:

TSPException - if the signature cannot be processed or the provider cannot match the algorithm.

toCMSSignedData

public CMSSignedData toCMSSignedData()

Return the underlying CMSSignedData object.

Returns:

the underlying CMS structure.

getEncoded

public byte[] getEncoded()
                  throws IOException

Return a ASN.1 encoded byte stream representing the encoded object.

Throws:

IOException - if encoding fails.
