SIGN

Signature Validation

Check the validity of signatures by using visual cues, such as a green checkmark for a valid signature or a red X for an invalid signature.

Use digital signatures like you use any signature on paper. For example, a digital signature can be used to:

Approve a document
Indicate that you have reviewed a document
Accept a document's stated terms
You can also use digital signatures in Acrobat to detect and track changes made to a document.

When you certify a document with a digital signature, it indicates that the document originated from you and hasn't been altered since certification.
