Hi all,

Recently we've realized that some Signature was Identify as invalid by Nitro (v In Adobe it's perfectly recognized it.

When we opened the properties of the signature all buttons (Validate Signatures / View certificate / Add to Trusted Contacts) are grey, so I can't click on it to try to add it.


Is there any reason why it could happen ? It really looks that Nitro Pro didn't recognize the signatures. Is the signature algorithm : RSA with SSA-PSS (PKCS#1 v2.1 with Hash of SHA512) really recognize by this version 12 ?


Thanks for your response
