Subject: Senior M$ member says stop using passwords completely!

I was under the understand that passwords of over 14 characters were
stored with a more secure hash, therefore 14 characters passwords were
harder to crack, due to the more secure hash. Windows will create two
different hashes for passwords shorting than 14 characters, I do
believe.

Just use a non-printable character in your password and cracking is
useless...if they crack it, they can't read what they cracked. ;)
