What is a digital signature?

A digital signature is an electronic, encrypted, stamp of authentication on digital information such as e-mail messages, macros, or electronic documents. A signature confirms that the information originated from the signer and has not been altered.

Signing certificate and certificate authority

Signing certificate     To create a digital signature, you have to have a signing certificate, which proves identity. When you send a digitally-signed macro or document, you also send your certificate and public key. Certificates are issued by a certification authority, and like a driver's license, can be revoked. A certificate is usually valid for a year, after which, the signer must renew, or get a new, a signing certificate to establish identity.

Certificate authority (CA)     A certificate authority is an entity similar to a notary public. It issues digital certificates, signs certificates to verify their validity and tracks which certificates have been revoked or have expired.

What does a digital signature guarantee?

  • Authenticity     The signer is confirmed as the signer.

  • Integrity     The content has not been changed or tampered with since it was digitally signed.

  • Non-repudiation     Proves to all parties the origin of the signed content. Repudiation refers to the act of a signer denying any association with the signed content.

  • Notarization     Signatures in Word, Excel, or PowerPoint files, which are time stamped by a secure time-stamp server, under certain circumstances, have the validity of a notarization.

To make these assurances, the content creator must digitally sign the content by using a signature that satisfies the following criteria:

  • The digital signature is valid.

  • The certificate associated with the digital signature is current (not expired).

  • The signing person or organization, known as the publisher, is trusted.

    Important:Signed documents, which have a valid time stamp, are considered to have valid signatures, regardless of the age, or revocation status, of the signing certificate.

  • The certificate associated with the digital signature is issued to the signing publisher by a reputable certificate authority (CA).

Signature lines in Word and Excel

A signature line resembles a typical signature placeholder that might appear in a printed document. However, it works differently. When a signature line is inserted into an Office file, the author can specify information about the intended signer, and instructions for the signer. When an electronic copy of the file is sent to the intended signer, this person sees the signature line and a notification that their signature is requested. The signer can:

  • Type a signature, or

  • Select a picture of an inked signature, or

  • Write a signature by using the inking feature of a touch-screen PC

When the signer adds a visible representation of a signature to the document, a digital signature is added at the same time to authenticate the signer's identity.
