	static method getBytes  [line 40]





	

    

    
 
		static string getBytes(
int
$num_bytes 
)
    

    



	
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.

			Parameters:

			

					

				int  
				
				$num_bytes: 
				
				 The length of the return value			

				


	

	API Tags:



  

    Return:  random bytes

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



			Parameters:

			

					

				integer  
				
				$length: 
				
				 The length of the resulting  randomly-generated string			

					

				string  
				
				$chrs: 
				
				 A string of characters from which to choose  to build the new string			

					

				  
				
				$population:
