---------------------------------------

Ugh. A massive brain cramp today caused me to write that last comment. Please forgive. The
salts, of course, are included as part of the password string..... never mind the keystore
gibberish.

> The password hash is calculated as a direct SHA1-digest of the password.  Unfortunately
this means that it's vulnerable to brute-force attacks - there are many web sites which store
SHA1 hashes of common passwords.  The key space in most languages is pretty small... So the
password should really be properly salted with preferably a long, random string.
