for future reference. boingboing quotes this article on passwords:
PRTK also runs a four-character-string exhaustive search. It runs the dictionaries with lowercase (the most common), initial uppercase (the second most common), all uppercase and final uppercase. It runs the dictionaries with common substitutions: "$" for "s," "@" for "a," "1" for "l" and so on. Anything that's "leet speak" is included here, like "3" for "e."
The appendage dictionaries include things like:
- All two-digit combinations
- All dates from 1900 to 2006
- All three-digit combinations
- All single symbols
- All single digit, plus single symbol
- All two-symbol combinations
