In my experiments, I have found the range of the byte array to be truly random. In a test that I ran, once it created a byte array of size 8890 while in another time, it created an array so large, I lost my patience and had to quit the process. This poses a problem where your program could take a long time to generate your secret.

When you say "random binary vector" I think each digit has a 50% chance of being 0 or 1. What you have actually generated are binary vectors where each digit has a far greater chance of being a 0 than a 1.

Compatibility In C, the generation algorithm used by rand is guaranteed to only be advanced by calls to this function. In C++, this constraint is relaxed, and a library implementation is allowed to advance the generator on other circumstances (such as calls to elements of <random>). The Random.Next() method returns a random number in C#. The Random class's RandomByte and RandomDouble method returns a random byte and and a random double integer. The code examples show how to generate a random string and random integer in C# and .NET.
