Effectively, any one possessing the key can decrypt the message being transferred. This is used as a secret private key for the interaction. The header tells us the encryption algorithm that was used: in. With , public key authentication improves security considerably as it frees the users from remembering complicated passwords or worse yet, writing them down. In a nutshell: A pair of encryption keys are generated which are mathematically linked to each other: a private key and a public key. . The motivation for using public key authentication over simple passwords is security.

One key pair is known as a host server key, the other as a user client key. When a private key is needed the user is asked to supply the passphrase so that the private key can be decrypted. These credentials securely pass through the symmetrically encrypted tunnel, so there is no chance of them being captured by a third party. I know that the name is not important. Entering a passphrase does have its benefits: the security of a key, no matter how encrypted, still depends on the fact that it is not visible to anyone else.
