Certificate Uses

Digital certificates can be used to identify a person or a device. Once identification is established, the certificate is most frequently used to prove one person’s, or device’s, identity to another person or device. Because of the RSA system, they both know each other. The digital certificate can now be used for signing and/or encrypting email or for providing two-factor strong authentication.

Using the dual-key cryptography algorithm, the digital certificates allow users to exchange public keys to secure and authenticate each other.

There are two main uses for digital certificates are for:
