Self-signed certificates are a type of security certificates that are signed by the same entity that actually uses the certificate. A self-signed certificate is usually signed by an own, custom generated private key. Usually, a public key is also available from the certificating authority - it provides the option for the user or organization to test it against the own private key which is used for signing.
