A [[wp>Public-key_cryptography|public-key cryptography]], also known as asymmetric cryptography, is a class of cryptographic algorithms which requires two separate keys, one of which is secret (or private) and one of which is public.((&wikipedia_ref(Public-key_cryptography|Public-key cryptography))) Together they are known as a key pair. In %%SSH%%, the public key cryptography is used in both directions (client to server and server to client), so two key pairs are used.

| - | A //user private key// is a key kept secret by the %%SSH%% user on his/her client machine. The user must never reveal the private key to anyone, including the server (server administrator), not to compromise his/her identity. | + | MIIEpAIBAAKCAQEAi+D6tOmB0uDx4n9ldVKrCvRHyOKSS0Su2D3hUfFfzCF9j7el |

| - | To protect the private key, it should be generated locally on a user's machine (e.g. using [[ui_puttygen|PuTTYgen]]) and stored encrypted by a passphrase. The passphrase should be long enough (that's why it's called passphrase, not password) to withstand a [[wp>Brute-force_attack|brute-force attack]] for a reasonably long time, in case an attacker obtains the private key file. | + | ejXvOjCrwz1EYn5djW/XSHuQ03pahUFedP7Bp9sh99zjrF5VQFAhVzXLuKaFEyEK |
