I pulled this information out of the cccure.org's domain 1 of the CISSP. I don't have a link for it as I downloaded it as a doc a long time ago, but if anyone wants the doc it is up on their site somewhere. Not related to a specified app, but still relative info.
Some examples of password strengths:
Password Type | Length | Possible combinations | Estimated Time to Crack
Alpha (Case in-sensitive) | 6 characters | 308,915,776 | Less than a minute
Alpha (case sensitive) | 6 characters | 19,770,609,664 |1 days
Alpha (case sensitive) and numeric | 6 characters | 56,800,235,584 | 3 days
Alpha (case sensitive), numeric and symbols | 6 characters | 606,355,001,344 | 5 weeks
Alpha (case sensitive), numeric and symbols | 9 characters | 472,161,363,286,556,672 | 77 thousand years
The estimates above are based on a rate of 100,000 attempts per seconds and assume that half of the key space must be searched. Notice how lengthening the password length has a dramatic effect on the size of the search space.
