Cryptographically secure random data generation.

Usage

Hex string

Random string of hexadecimal characters ([0-9a-f]).

use bfrohs\Random\Random;

$string = Random::generateHex(32);

var_dump($string);

string(32) "112321ec33df8ebc9234ac02dbae4277"

Url-safe string

Random string that is safe for use in URLs (unreserved characters) per RFC 3986 § 2.3 ([a-zA-Z0-9], _, ~, -, and .).

use bfrohs\Random\Random;

$string = Random::generateUrlSafeString(32);

var_dump($string);

string(32) "XQ_7J495ZWd3s~5TWz-FNFiPkeM3z9K."

Binary

Random bytes.

use bfrohs\Random\Random;

$string = Random::generateBinary(32);

// Note the use of `bin2hex()` to make output readable
var_dump(bin2hex($string));

string(64) "68a74f84be34c9be12ecada360e91639fd0d41cfae368d90fe8cc4c4ff66eed3"

Integer

Random integer.

use bfrohs\Random\Random;

$string = Random::generateInt(0, 29524);

var_dump($string);

int(12860)
