Methods summary
`public static string`	# `getBytes( integer $num_bytes )` Get the specified number of random bytes. Get the specified number of random bytes. Attempts to use a cryptographically secure (not predictable) source of randomness if available. If there is no high-entropy randomness source available, it will fail. As a last resort, for non-critical systems, define Auth_OpenID_RAND_SOURCE as null , and the code will fall back on a pseudo-random number generator. Parameters `$num_bytes` The length of the return value Returns string $bytes random bytes
`public static string`	# `randomString( integer $length, string $population = null )` Produce a string of length random bytes, chosen from chrs. If $chrs is null, the resulting string may contain any characters. Produce a string of length random bytes, chosen from chrs. If $chrs is null, the resulting string may contain any characters. Parameters `$length` The length of the resulting randomly-generated string `$population` $chrs A string of characters from which to choose to build the new string Returns string $result A string of randomly-chosen characters from $chrs
`public static`	# `constEq( $s1, $s2 )`
