Key File Authentication
Key authentication uses a randomly generated pair of keys, one private, one public,
consisting of unique strings of binary data. A copy of the public key is placed in all the
accounts to be accessed on the SSH server machines. Your private key, which is
protected using a Passphrase, is stored on your local SSH client machine. During
authentication, the client and server compare information on the private and public
keys and if they match, your identity is proved.
Authentication keys need to be generated and stored on the client and server before
any connections can be made. To generate a key, click the Generate Key button to
display the following dialog box.
The Filename is the root filename for all the generated key files. DSA and RSA are
the two types of algorithms used to generate a public key, RSA being the most widely
used.
If you want to generate a new set of large prime numbers to use in the key generation
process, click the New Group button. Note that this can take a relatively long time to
achieve. Multiple keys can be generated from the same group of prime numbers.
To generate a pair of keys, click the Generate Key button. You will be prompted for a
Passphrase.
