Compare possible brute force combinations: (26+10)^5 vs. 10^12

That would be 10e12 vs 60.466.176. Pretty easy from the security pov.

Also if an alphanumeric string should be entered / remembered by humans make sure to strip I, l, etc.

For case-sensitive alphanumeric: (26+26+10)^5

Which is still far lower than 12 digits.
