str::quickRandom($length = false, $type = 'alphaNum')

• since: Kirby 2.4.0
• $length (int)
  The length of the random string
• $type (string)
  Pool type (type of allowed characters)
• return (string)
  

This method is faster than (toolkit: str/random) in most cases, but should not be considered sufficient for cryptography, etc.
Please note that str::random can sometimes be faster, e.g. when the pool is very large (e.g. 'alphaNum' or 'alpha').
