Duncan,
Warm on one, correct on one and yours was "crackable" as you are probably aware
A secure password is not viewable in any way. For example a password of "fishing" is stored as "819a07afa4abc8660ec9042038a8c597" this could also be the code stored for the complete works of shakespere encoded !
"Fishing" is easily guessed but easily found when a computer can try out thousands/millions of passwords per sec.
To be honest, I only tried it out of interest and it shocked me.
I can only guess the password from the calculated number. When users have simple ones then a program can easily guess it in seconds.
Another thing I have found that can be done which even opened my eyes, is theprogram can dump the "protected storage" areas of the PC you are on. This contains all my so called "secure" passwords. Bank account details, credit card details etc. - astounding.
If you sell your PC, I would erase the hard drive if I were you !
