Upgrade to stronger keys over time ("key rotation"), which replaces the public key in theĬertificate with a new one. There are several downsides to this simple approach. If the certificate is not in the set, the Have a set of one or more certificates it trusts. One way to solve this problem is to have the client Matches the public key of the certificate. However, anyone can generate their own certificate and private key, so a simple handshakeĭoesn't prove anything about the server other than that the server knows the private key that As part of the handshake between an SSL clientĪnd server, the server proves it has the private key by signing its certificate with public-key cryptography. Public key as well as a matching private key. In a typical SSL usage scenario, a server is configured with a certificate containing a To your app, this article highlights the common pitfalls when using secure network protocols and addresses some larger concerns about using Public-Key Infrastructure (PKI).
