Verify Method

Verifies a signed PDF document.

Syntax

ANSI (Cross Platform)
int Verify();

Unicode (Windows)
INT Verify();
- (void)verify;
#define MID_PDFVERIFIER_VERIFY 4

SECUREBLACKBOX_EXTERNAL int SECUREBLACKBOX_CALL SecureBlackbox_PDFVerifier_Do(void *lpObj, int methid, int cparam, void *param[], int cbparam[], int64 *lpllVal);

Remarks

Use this method to validate all signatures in a PDF document.

This method walks through a signed document and reports every signature via a SignatureFound event. Subscribe to the event to be notified about the signatures and adjust validation settings on the fly.

Upon completion of this method the signature details will be published in Signatures property.

This method only validates the signatures, but does not check their coverage. It is a good idea to use mechanisms such as GetSignedVersion or CoverageEndsAt to ensure that the signature covers the expected document revision.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
