Retype your pass phrase, and then press Return. We decided to re-evaluate our commenting platform to ensure that it meets your expectations and serves as an optimal feedback mechanism.

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.

The associated public key can be shared freely without any negative consequences. This is an optional passphrase that can be used to encrypt the private key file on disk. The most basic of these is password authentication, which is easy to use, but not the most secure.

This will let us add keys without destroying previously added keys. When the two match up, the system unlocks without the need for a password.

Enter passphrase empty for no passphrase : It's up to you whether you want to use a passphrase. Technically, at this point, the setup is complete. You assume incorrectly or, at least, incompletely. It is based on the difficulty of computing discrete logarithms.

This means that other users on the system cannot snoop.
