I used below function to create random token, and also a salt from the token. I used it in my application to prevent CSRF attack.
<?php
function RandomToken($length = 32){
if(!isset($length) || intval($length) <= 8 ){
$length = 32;
}
if (function_exists('random_bytes')) {
return bin2hex(random_bytes($length));
}
if (function_exists('mcrypt_create_iv')) {
return bin2hex(mcrypt_create_iv($length, MCRYPT_DEV_URANDOM));
}
if (function_exists('openssl_random_pseudo_bytes')) {
return bin2hex(openssl_random_pseudo_bytes($length));
}
}
function Salt(){
return substr(strtr(base64_encode(hex2bin(RandomToken(32))), '+', '.'), 0, 44);
}
echo (RandomToken());
echo 'n';
echo Salt();
echo 'n';
/*
This function is same as above but its only used for debugging
*/
function RandomTokenDebug($length = 32){
if(!isset($length) || intval($length) <= 8 ){
$length = 32;
}
$randoms = array();
if (function_exists('random_bytes')) {
$randoms['random_bytes'] = bin2hex(random_bytes($length));
}
if (function_exists('mcrypt_create_iv')) {
$randoms['mcrypt_create_iv'] = bin2hex(mcrypt_create_iv($length, MCRYPT_DEV_URANDOM));
}
if (function_exists('openssl_random_pseudo_bytes')) {
$randoms['openssl_random_pseudo_bytes'] = bin2hex(openssl_random_pseudo_bytes($length));
}
return $randoms;
}
echo 'n';
print_r (RandomTokenDebug());
?>
Comcreateguid ( void): string Generates a Globally Unique Identifier (GUID). A GUID is generated in the same way as DCE UUID's, except that the Microsoft convention is to enclose a GUID in curly braces. Random String Generator. This form allows you to generate random text strings.
