Generate Host Private Key Dialog Box

Getting there

From this dialog box, you can generate a new host key.

Note: Generating a new key automatically updates the value for Private key on the Identity tab. Use File > Save to save this change to your configuration file.


Host key

Specifies the filename for the generated private key. (A public key is also created and is always given the same name as the private key plus a .pub file extension.) To edit the filename or change the folder location, click Browse.


Key size

Specifies the key size. Up to a point, a larger key size improves security. Increasing key size slows down the initial connection, but has no effect on the speed of encryption or decryption of the data stream after a successful connection has been made. The length of key you should use depends on many factors, including: the key type, the lifetime of the key, the value of the data being protected, the resources available to a potential attacker, and the size of the symmetric key you use in conjunction with this asymmetric key. To ensure the best choice for your needs, we recommend that you contact your security officer.

The list of available sizes includes commonly used key sizes. If you need a key with a different size, you can use the ssh-keygen command line utility. (Key sizes specified with this utility are rounded up to the next value evenly divisible by 64 bits.)


Key type

Specifies the algorithm used for key generation.
