I cannot remember the exact typing of my old laptop's passphrase. It is encrypted, after an hour of random typing I got the passphrase once and am now stuck on my Linux Mint 17 or 18 login screen, faced with the same passphrase.

It's something like this:

SimplePhraseOfMine with the possibility of upper/lowercase and s=5 o=0 e=3

I've tried writing all variations by hand, but that is tedious and I've not gotten it. I tried messing around with Crunch wordlist generator, but that doesn't seem to do exactly what I need (keep that phrase intact).

Is there a program to do this?
