Does SSL certificate contains public key?
When performing authentication, SSL uses a technique called public-key cryptography. The owner of the key pair makes the public key available to anyone, but keeps the private key secret. A certificate verifies that an entity is the owner of a particular public key.
What are the problems with SSL?

How does a client request a certificate from a server?
The server also sends its own digital certificate and, if the client is requesting a server resource that requires client authentication, requests the client’s digital certificate. The client uses the information sent by the server to authenticate the server.
Where does the digital signature go in the certificate chain?
A digital signature of the CA along with the server’s public key is attached in the certificate chain, and the client verifies all the signatures in the certificate till the root CA certificate is gained. 4. Server Key Exchange Message:
What happens if the server cannot authenticate the client?
The client uses the information sent by the server to authenticate the server. If the server cannot be authenticated, the user is warned of the problem that an encrypted and authenticated connection cannot be established. If the server can be successfully authenticated, the client proceeds.
