Digital Signature System after Goldwasser, Micali and Rivest with null for empty message?


Tag : java , By : Sebastian Gift

This might help you Now I excluded the empty message from signing with GMR Digital Signature System. I do not think, that a NULL Pointer gives a valid signature path/tree.

How to display different images based on validity of digital signature using pdfbox api?

it should still fix some issue Such variable graphics have been deprecated more than a decade ago; Adobe Reader probably still supports them but there is no telling for how long. Depending on your signature profile they actually are forbidden!
Please use a neutral graphic (no check mark, no cross, no question mark icon) for your signature and determine the validation state from the signature tab of the PDF viewer.

Is length of Digital Signature is digital token(digital certificate) dependent?

I hope this helps . It depends on the digital signature format you are using.
A basic signature container (i. e. PKCS#1) includes only the signed hash. An advanced format can include the certficate itself too or a reference to the certificate.

Is there a way to add a digital signature to visio? Can I use VBA to display my digital signature on my Visio form?

wish help you to fix your issue The only aspects of Visio that can have a digital signing certificate applied are documents that contain VBA macros (.VSDM, .VSSM and .VSTM files) and Visio add-ons (.EXE amd .VSL (.DLL) files). Forms embedded within Visio files cannot be separately signed. When exported to PDF format any digital signing is not carried over.

To prove no data tampering the user will use the Digital Signature which will be the hash of the certificate with the private key of the user.
