Summary

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

To create a digital signature, you need 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, signing certificate to establish identity.

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 It issues digital certificates, signs certificates to verify their validity and tracks which certificates have been revoked or have expired.

Warnung

Do not perform these steps more than once! Only the two most recently downloaded certificates are valid.

A certificate is not exchangeable. Mails that have been encrypted by a certificate can only be decrypted by that same certificate. If you lose your previously used certificate, signatures can no longer be verified and encrypted items can no longer be decrypted. Therefore, save it on your home drive or on an encrypted USB stick. Remember your assigned password for the certificate or keep it in a safe place.

Step 1: Apply for a group certificate at the service desk of the university computer center.
