The larger the key size, the more secure the resulting key will be but the longer it will take the server to generate the key. When you click Generate Key, be patient; this process can take time. When the key has been created, you will be informed. Once the key has been created, the main OpenPGP screen will display the cryptographic fingerprint of both the public and private keys. You can then delete the keys or edit (copy) them by clicking the appropriate word next to each...
