What is the process of establishing a secure connection with SSL?
The process of establishing a secure connection with SSL involves several key steps. First, the client (usually a web browser) initiates a connection to the server by sending a “Client Hello” message, which includes the SSL version, cipher suites, and a randomly generated number. The server responds with a “Server Hello” message, selecting the SSL version and cipher suite to be used, and sends its digital certificate to the client. This certificate contains the server’s public key and is signed by a trusted Certificate Authority (CA), ensuring its authenticity.
Next, the client verifies the server’s certificate against a list of trusted CAs. If the certificate is valid, the client generates a pre-master secret, encrypts it with the server’s public key, and sends it to the server. Both the client and server then use this pre-master secret to generate session keys for encrypting the data transmitted during the session.
Finally, the client sends a “Finished” message, and the server responds with its own “Finished” message, indicating that the secure connection is established. This process ensures that data exchanged between the client and server is encrypted and secure from eavesdropping or tampering.
How do SSL Certificates encrypt data transmitted between users and websites?
SSL Certificates encrypt data transmitted between users and websites by establishing a secure connection using the SSL/TLS protocol. This process involves the exchange of cryptographic keys, where the server sends its public key to the user’s browser. The browser then generates a unique session key, encrypts it with the server’s public key, and sends it back to the server. Only the server can decrypt this session key using its private key, allowing both parties to communicate securely. This encryption ensures that any data exchanged, such as personal information or payment details, remains confidential and protected from eavesdropping or tampering during transmission.
