Create a SSH-2 RSA public/private key pair

1024 bit keys may be considered default, however 2048 is generally considered the minimum for reasonable security, and 4096 as a even more secure option.

Generating the key requires random data to be generated, to do this drag your mouse around the screen.

A public and private key is generated, and the public key is shown. Save your public and private key. Optionally you can enter a passphrase ("password") to be used when storing your private key.
