As someone who has ‘recovered’ mixed passwords before, I can assure it takes, at most, weeks to recover a password. Having said that, it doesn’t hurt to use mixed passwords. My password recovery software was, admittedly, altivec-enabled, so it was computing 128-bit chunks.
OTOH, you can shorten the time needed by assuming the password is 8 chars long, thus skipping 1-7 chars. On secure networks, this is a good assumption.
Well some people use simple combination passwords. And sometimes they use words that we can get from the dictionary.
In this case, it was none of the above. The password I “forgot” was actually pretty strong. Don’t take my word for it; use John the Ripper on your password hash. Set John to start at 8 chars. You’ll see what I mean. The password I forgot was ‘pac1west’ which isn’t succeptible to dictionary attacks…
Really? But I think it depends on how bigger your dictionary file is if you are using Dictionary Attack. :d
