public static java.util.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(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 certificate fails on one of the check points.
