dSignature solution allows to add one or multiple digital signatures to a PDF stored in a SharePoint library, simply by configuring the appropriate action in a SharePoint Designer or a Nintex workflow. The action adds a digital signature using one or more certificate that can be self-generated using your own server or purchased by a third party Certified Authority.

The certificate to be used is PKCS#12 certificate (extension “.pfx”): this type of certificate is encrypted with a private and a public key according to recognised standard that makes it safe and compliant with a wide range of regulation requirements.

The digital signature cannot be altered, and it represents a strong proof of user identity. The signature is safely saved as a part of the signed PDF document, that cannot be modified unless making the signature “not valid”.
