Hi, I'm about to implement the DSA algorithm, but there is a problem:

choose "p", a prime number with L bits, where 512 <= L <= 1024 and L is a multiple of 64

How to implement a random generator of that number? Int64 has "only" 63 bits length

Dynamic Type to do away with Reflection

In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
