Description
Saves and signs the current PDF.On success you either get back the PDF as container value (in memory PDF) or it returns OK after writing PDF to file (file based PDF).
No preview picture is added. Please use DynaPDF.GeneratePreview function if this is needed.
Same as DynaPDF.SaveAndSignFileExt, you need to create the signature and then call DynaPDF.SaveAndSignFileExt2 function to pass the final signature as hex string.
Returns hex encoded hash to sign.
As of v13.1 we have no MBS function to perform such a signature, but.we may add that if needed. But this function was made for people using external hardware to perform the signature.
Examples
Start signing process:
Set Variable [ $hash ; Value: MBS("DynaPDF.SaveAndSignFileExt1"; $pdf; "Test User"; "Chicago"; "") ]
Manually sign PDF content:
# manually load certificate and key
Set Variable [ $pkcs12 ; Value: MBS( "PKCS12.ReadFromFile"; "/Users/cs/Desktop/test_cert.pfx"; "123456") ]
# sign a test string to know size in advance
Set Variable [ $SampleSignature ; Value: MBS( "PKCS12.SignData"; $pkcs12; "hex"; "C9097E23869BC9903CE89E9562230C6FDCBC0F06"; ""; "hex"; "" ) ]
Set Variable [ $estimatedSignatureSize ; Value: Length($SampleSignature) / 2 + 5 ]
# now save and produce hash
Set Variable [ $hashToSign ; Value: MBS("DynaPDF.SaveAndSignFileExt1"; $pdf; "My ContactInfo"; "My Location"; "My Reason"; "My Signer"; $estimatedSignatureSize) ]
# sign the hash
Set Variable [ $Signature ; Value: MBS( "PKCS12.SignData"; $pkcs12; "hex"; $HashToSign; ""; "hex"; "" ) ]
# and finish the PDF
Set Field [ Merge PDFs::MergeStatus ; MBS("DynaPDF.SaveAndSignFileExt2"; $pdf; $signature; "Merged.pdf") ]
