An Introduction to OpenSSL, Part Three: PKI- Public Key Infrastructure

An Introduction to OpenSSL, Part Three: PKI- Public Key Infrastructure: "A certificate is the signature of a public key and information that describes the holder of the public key. The signature is created using an asymmetric cipher and a private key held by a CA. The CA's private key has a corresponding public key that is part of a root certificate. A root certificate is a public key and its corresponding information that has been signed by the private key that corresponds to the aforementioned public key. A root certificate is also called a self-signed certificate because the private key in a key pair is used to sign the public key and identifying information, instead using a private key from a different key pair to sign the public key and its identifying information."

what a load of crap!!!! you try and explain it????
