In cryptography, a shared secret is a piece of data, known only to the parties involved, in a secure communication. This usually refers to the key of a symmetric cryptosystem. The shared secret can be a password, a passphrase, a big number, or an array of randomly chosen bytes. The shared secret is either shared beforehand between the communicating parties, in which case it can also be called a pre-shared key, or it is created at the start of the communication session b… Webb/4 🔹 Protocol negotiation: Agree on the SSH protocol version and encryption algorithms. 🔹 Key exchange: Generate a shared secret key securely. 🔹 Server authentication: Verify the server's public key.
