תיאור

Attaches a DER-encoded X.509 certificate and an external digest-signing format to a PDF signing process

הספרייה בונה את אובייקט ה-CMS המנותק ושולחת רק את ה-digest הסופי של המאפיינים המאומתים שלו אל ה-callback הרשום

תחביר

Delphi

Function TPDFlib.SetSignProcessExternalDigestSigner(SignProcessID: Integer; Const CertificateDER: AnsiString; SignatureAlgorithm, SignatureReserveBytes: Integer): Integer;

ActiveX

Function PDFlib::SetSignProcessExternalDigestSigner(SignProcessID As Long, CertificateDER As Variant, SignatureAlgorithm As Long, SignatureReserveBytes As Long) As Long

DLL

int DLSetSignProcessExternalDigestSigner(int InstanceID, int SignProcessID, const char* CertificateDER, int CertificateLength, int SignatureAlgorithm, int SignatureReserveBytes);

פרמטרים

SignProcessID	Value returned by a `NewSignProcessFrom*` function
CertificateDER	Complete DER-encoded RSA or ECDSA X.509 certificate corresponding to the external private key
SignatureAlgorithm	`1` for RSA PKCS#1 v1.5, `2` for DER-encoded ECDSA, or `3` for ECDSA P1363 `r \|\| s`
SignatureReserveBytes	Expected upper bound for the raw signature, or `0` to derive it from the certificate public key

הערות

Assign OnExternalDigestSign, call DLSetExternalDigestSignCallback, or provide an ActiveX callback object with SetExternalDigestSignCallback before ending the sign processThe callback is not invoked while sizing the
