		static getBytes (line 40)
	
 
	
	

Get the specified number of random bytes.


Attempts to use a cryptographically secure (not predictable)  source of randomness if available. If there is no high-entropy  randomness source available, it will fail. As a last resort,  for non-critical systems, define  
  1. Auth_OpenID_RAND_SOURCE
    2. 

 as 
  1. null
    2. 

, and  the code will fall back on a pseudo-random number generator.

Produce a string of length random bytes, chosen from chrs.  If  $chrs is null, the resulting string may contain any characters.
