Method Detail

extractRevision

public byte[] extractRevision()

getRevision

public int getRevision()

Returns a revision value. The value starts with 1.

Returns:

verifyDocument

public boolean verifyDocument()

Verifies if the portion of PDF document has been modified a signature applied. This doesn't support Acrobat5 signed PDF document with adbe.pkcs7.detached because Acrobat5 generates the pkcs7 incorrectly. It looks like Acrobat7 and above generate pkcs7 object properly. However, I didn't verify Acrobat6 pkcs7 detached document.

Returns:: true if the document has not been modified.

verifyCertificates

public boolean verifyCertificates(java.util.Vector trustedCertificates,
                                  java.util.Vector crls)
                           throws CertificateNotYetValidException,
                                  CertificateExpiredException,
                                  CertificateRevokedException,
                                  NoTrustedCertificateException,
                                  NotVerifiedAgainstChainException,
                                  NotVerifiedAgainstTrustedRoot

Verifies if the certificate chain used to sign the document is valid against the trusted (root) certificates. The trustedCertificates should contain at least on File instance which points to a root CA, otherwise, NoTurstedCertificateException is thrown. The crls can be a null if there is no Certificate Revocation List.
