Yet another Random password generator

By Matt5150 on May 13, 2013

A custom length password generator

Example usages:
$rpass(N)

//echo -a Random password 10 characters long: $rpass(10)

Results:

iuqk2JQmEp
0L6073x4v4
3UB5Pq5dwN
2dT8y2NxA6
FETerh2SS7

alias rpass {
  var %:a = $1, %:rpass
  while (%:a) {
    if ($regex($r(1,3),1)) { var %:rpass = %:rpass $+ $r(0,9) }
    else { var %:rpass = %:rpass $+ $iif($regex($r(1,2),1),$r(a,z),$r(A,Z)) }
    dec %:a
  }
  return %:rpass
}

Seems much more compact than the one I rigged up a few days ago for a snippet I used to generate MD5 Hashes from random strings, or passwords if you will.

Yeah! There are a lot of random string snippet XD
I was bored, so I decided to make my own "random pass generator"
As you can see, there is 1/3 chance to return a number otherwise a letter (50% uppercase 50% lowercase).

I don't think arrays are built in to mIRC which is a shame. I believe I used a pre-existing character set builder class to specify which set to build from. So it can be modified to use only upper, lower, both, numerical, alpha numerical, or all characters (to a certain degree). Chosen at random, of course.

I don't understand the use of $regex() in

$iif($regex($r(1,2),1),$r(a,z),$r(A,Z))

when you can use

$iif($r(0,1),$r(a,z),$r(A,Z))

The same goes for the if statement further up. If you want it to be more readable, use $r(0,1) == 1 for example.

Yeah I know that, but I used regex to make it "a little" different from the others :P
there are a lot of ways, for example letters $r(a,b)
or things a little more elaborate, like this ($right($calc($r(1,10) / 2),2) = .5)

If you're wanting to stand out, efficiency is the place to do it. Regular expressions do a lot of string parsing, which ultimately means you end up doing much more work than necessary. Size is nothing, speed is everything.
