What is the TLS Handshake Protocol?
The Transport Layer Security (TLS) Handshake Protocol is responsible for the authentication and key exchange necessary to establish or resume secure sessions. When establishing a secure session, the Handshake Protocol manages the following: Authentication of the server and optionally, the client.
What do I do with SSL private key?
Note: At no point in the SSL process does The SSL Store or the Certificate Authority have your private key. It should be saved safely on the server you generated it on. Do not send your private key to anyone, as that can compromise the security of your certificate.
How is a public key used in a TLS handshake?
The server encrypts some data with the private key, and the client uses the public key to decrypt it, proving that the server has the correct key and is legitimate. What is the ‘master secret’ in a TLS handshake?
What happens to PreMaster secret in SSL handshake?
The premaster secret: The client sends one more random string of bytes, the “premaster secret.”. The premaster secret is encrypted with the public key and can only be decrypted with the private key by the server. (The client gets the public key from the server’s SSL certificate.)
What happens in a client hello SSL handshake?
Client hello: The client sends a client hello message with the protocol version, the client random, and a list of cipher suites. Server hello: The server replies with its SSL certificate, its selected cipher suite, and the server random.
Do you need PKI to use TLS client authentication?
To use TLS client authentication, you must first set up PKI (Public Key Infrastructure) infrastructure to issue client certificates. If you are interested in running TLS client authentication but don’t have PKI infrastructure set up to issue client certificates, we have open sourced our PKI for you to use.
