Generate A Key In Php
Key generator windows 7 professional 64. If set to TRUE, uniqid will add additional entropy (using the combined linear congruential generator) at the end of the return value, which increases the likelihood that the result will be unique. Return Values. You can create SAS for a queue, topic, subscription, Event Hub, or relay. If you use per-publisher identity for Event Hubs, you can append /publishers/. If you give a sender or client a SAS token, they don't have the key directly, and they cannot reverse the hash to obtain it.

Generate A Key In Php Word
Nice function guys. I will be using it to write a function for generating card pins for web login. Pins generated are stored on a database. When a pin is generated it is matched with the ones on the database if it exits, it is discarded if not exit, it is added to the database.
What do you think?
What about uniqueness?
fuck
Php Get Key For Value
nice, i use something similar
<?php
function generatekey($length)
{
$options = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789';
$code = ';
for($i = 0; $i < $length; $i++)
{
$key = rand(0, strlen($options) - 1);
$code .= $options[$key];
}
return $code;
}
// echo generatekey(10); // Ko9B69utve, returned result is random. not only is this good for ac validatin but has several other applicvations, eg captch ect its uses are limitless.

Php Key Function
Here's my final version of a GUIDv4 function (based on others work here) that should work on all platforms and gracefully fallback to less cryptographically secure version if others are not supported..
<?php
/**
* Returns a GUIDv4 string
*
* Uses the best cryptographically secure method
* for all supported pltforms with fallback to an older,
* less secure version.
*
* @param bool $trim
* @return string
*/
function GUIDv4 ($trim = true)
{
// Windows
if (function_exists('com_create_guid') true) {
if ($trim true)
return trim(com_create_guid(), '{}');
else
return com_create_guid();
}
// OSX/Linux
if (function_exists('openssl_random_pseudo_bytes') true) {
$data = openssl_random_pseudo_bytes(16);
$data[6] = chr(ord($data[6]) & 0x0f 0x40); // set version to 0100
$data[8] = chr(ord($data[8]) & 0x3f 0x80); // set bits 6-7 to 10
return vsprintf('%s%s-%s-%s-%s-%s%s%s', str_split(bin2hex($data), 4));
}
// Fallback (PHP 4.2+)
mt_srand((double)microtime() * 10000);
$charid = strtolower(md5(uniqid(rand(), true)));
$hyphen = chr(45); // '-'
$lbrace = $trim ? ' : chr(123); // '{'
$rbrace = $trim ? ' : chr(125); // '}'
$guidv4 = $lbrace.
substr($charid, 0, 8).$hyphen.
substr($charid, 8, 4).$hyphen.
substr($charid, 12, 4).$hyphen.
substr($charid, 16, 4).$hyphen.
substr($charid, 20, 12).
$rbrace;
return $guidv4;
}
?>
