Auth_OpenID_CryptUtil:: (2 methods):
getBytes()
randomString()
Class: Auth_OpenID_CryptUtil - X-Ref
| getBytes($num_bytes) X-Ref |
| 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 <code>Auth_OpenID_RAND_SOURCE</code> as <code>null</code>, and the code will fall back on a pseudo-random number generator. param: int $num_bytes The length of the return value return: string $bytes random bytes |
| randomString($length, $population = null) X-Ref |
| Produce a string of length random bytes, chosen from chrs. If $chrs is null, the resulting string may contain any characters. param: integer $length The length of the resulting param: string $chrs A string of characters from which to choose return: string $result A string of randomly-chosen characters |
