This request renames SecureRandom.choose to .with_chars and makes it public.
(I think it would be a better name.)

For example, when generating passwords for users,
I'd like to avoid using characters "O" and "0" (or I, l, 1, ...) because they are confusing.
SecureRandom.with_chars would be useful to do this.

[matz (Yukihiro Matsumoto)]

I don't like the name with_chars. It doesn't describe the intention and the behavior of the method.

This function is called "sampling with replacement" in mathematics and statistics.

[knu (Akinori MUSHA)]

I'd vote for SecureRandom.random_chars(len=16, candidate_chars).
