Questions tagged [certificate]

A certificate is an electronic document used in cryptography.

In cryptography, a public key certificate (also known as a digital certificate or identity certificate) is an electronic document which uses a digital signature to bind a public key with an identity — information such as the name of a person or an organization, their address, and so forth. The certificate can be used to verify that a public key belongs to an individual.

See the Wikipedia entry for more background and concepts regarding certificates.
