# Talk:Grid certificates

### From SNIC Documentation

The introduction isn't good. We need some more stuff about what Public Key encryption and certificates really is. /jens

"A certificate consist of 2 parts a private key and a public key." is wrong. A certificate is a public key and an identity signed by a another key pair, possible belonging to a trusted CA. /jens

"The public key is used to verify signatures are signed with your private key for the receiving part. The public part is also used to verify that the certficate is correct when you have the public part of the CA certificate." makes no sense. /jens
