password math
An interesting article: Password size does matter.
The obvious math quiz: For a given L, 256**L is a larger key space than 32**L. However, in practice the comparison even with forced “complex” passwords is probably closer to (92**2)*(32**(L-2)) than 256**L or even 92**L. Simple question: On average, how much longer do simple passwords have to be to fill a larger key space than the kind of “complex” passwords people can actually remember?
