Method Detail

getTimeStampInfo

public TimeStampTokenInfo getTimeStampInfo()

getSID

public kz.gamma.cms.SignerId getSID()

getSignedAttributes

public kz.gamma.asn1.cms.AttributeTable getSignedAttributes()

getUnsignedAttributes

public kz.gamma.asn1.cms.AttributeTable getUnsignedAttributes()

getCertificatesAndCRLs

public java.security.cert.CertStore getCertificatesAndCRLs(java.lang.String type,
                                                           java.lang.String provider)

Throws:

java.security.NoSuchAlgorithmException

java.security.NoSuchProviderException

kz.gamma.cms.CMSException

validate

public void validate(java.security.cert.X509Certificate cert,
                     java.lang.String provider)
              throws TSPException,
                     TSPValidationException,

                     java.security.cert.CertificateNotYetValidException,
                     java.security.NoSuchProviderException

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

java.security.cert.CertificateExpiredException

java.security.cert.CertificateNotYetValidException

java.security.NoSuchProviderException

toCMSSignedData

public kz.gamma.cms.CMSSignedData toCMSSignedData()

Return the underlying CMSSignedData object.

Returns:

the underlying CMS structure.

getEncoded

public byte[] getEncoded()
                  throws java.io.IOException

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

Throws:

java.io.IOException - if encoding fails.
