Re^3: Removing similar characters

You are right, but at 15 characters it takes .02s on my hardware. I did notice that randomregex() will emit consecutive duplicates rather frequently - I didn't check to see if a new instance of String::Random in each iteration would reduce that at all (or enough to make a difference in execution time).

For what I'm doing, speed isn't much of an issue. However, a friend of mine is using it on a project that he's working on, so it could cause a problem there. Although, the script has been tested up to a 500 character password, so I'm trying to eliminate any restrictions which could occur with abnormally large passwords. (Not that I'd expect anyone to have the need for a 500 character password.)	[reply]

My code falls over at around 40 - 50 characters due to throwing the entire string away.	[reply]

I don't expect that another instance should change behavior. Looking at the internals of String::Random, perl's built-in `rand` is what is used for randomness. From perldoc: `rand() is not cryptographically secure. You should not rely on it in security-sensitive situations. As of this writing, a number of third-party CPAN modules offer random number generators intended by their authors to be cryptographically secure, including: Math::Random::Secure, Math::Random::MT::Perl, and Math::TrulyRandom.` This is maybe something the OP should take note of.
