I've always understood the output of entropy estimators to me "the
entropy is no greater than this", which is somewhat easier to define,
since

Don't use PPTP and don't get tangled up in ipsec configuration hell.

I just realized where the discrepancy comes from: you *replaced* one

That calculator is giving you bits *per character*.
You can
I use a password generator of my own design - basically takes the userid,
concatenated with a fairly long secret phrase, and then I do SHA1 and
convert it to base64, giving a password like:
Acgq75VpCWjdsJaa5abe9JeX3I (don't worry, this isn't a real password to
