Method Detail

getTimeStampInfo

public TimeStampTokenInfo getTimeStampInfo()

getSID

public org.bouncycastle.cms.SignerId getSID()

getSignedAttributes

public org.bouncycastle.asn1.cms.AttributeTable getSignedAttributes()

getUnsignedAttributes

public org.bouncycastle.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,
                                                           org.bouncycastle.cms.CMSException
Throws:
java.security.NoSuchAlgorithmException
java.security.NoSuchProviderException
org.bouncycastle.cms.CMSException

validate

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