// This class handles login, meaning that it retrieves the SSL password from either
// the keyring or help.dta file, if autologin is enabled, or from the ssl_passphrase.pgp
// file, asking for the GPG password to decrypt it.
//
// This class should handle the following scenario:
//
// Normal login:
// 	- SSL key is stored  ->  do autologin
// 	- SSL key is not stored
// 			- if we're actually in the login process, ask for the gpg passwd, and decrypt the key file
// 			- if we're just trying for autologin, don't ask for the gpg passwd and return null
//
// Key creation:
// 	- the key should be stored in the gpg file.
//
