Document Signing Certificates


Document Signing certificates (also known as Advanced Electronic Signatures or Advanced Electronic Seals) are digital certificates that can be used to sign or seal digital documents like Adobe PDF files or Microsoft Office files.

When you digitally sign or seal a document using a certificate, the person you send the document to will know that it came from you, and that is hasn’t been tampered with or changed.

This is absolutely essential for many types of business-related documents such as contracts, bills, and financial documents.

Speed up document signing and make it more secure

Digital signing can simplify and speed up various business workflows, such as signing employee contracts, approval of financial documents, and execution of legal agreements.

Digital signatures can be executed remotely using any computer or other portable devices on which the document signing certificate is stored. Unlike a handwritten signature, a certificate-based signature is difficult to forge because it contains encrypted information that is unique to the signer.

Certifying a document

Adding a certifying signature (sealing a document) confirms that you are the author of the document, that you have finalized its contents, and that you want to secure it against tampering after it has been distributed.

Certified documents display a blue ribbon across the top of an Adobe document containing both the signer’s name and the certificate issuer — a clear, visual indicator of document authenticity and authorship.

Sign (approve) a document

Approval signatures — also referred to as digital signatures in the Adobe interface — are performed when someone (an individual or a department) signs a document to show consent, approval, or acceptance.

Adding a visible approval signature is the equivalent of signing your name on a physical document. Valid approval signatures unlock a green checkmark at the top of the Adobe interface.

Digital signatures versus electronic signatures

Electronic signatures and digital signatures are often presented as two sides of the same coin, but the truth is that these two concepts are very different.

The main difference between electronic and digital signatures is that digital signatures (Advanced Electronic Signatures and Advanced Electronic Seals) are based on cryptography, but also subject to a validation process performed by a certificate authority. In contrast, electronic signatures have no or very poor built-in validation and security.
