Generates a random key, a-Z 0-9 with no max length

• Php Generate Random Token

Usage

Mac generate new ssh key pair. This package can generate and validate software license keys. It takes as parameters several values like the name of the licensed user, license date, application id and the user computer host name. The package can generate a string that combines these parameter values using hashing algorithm. On the server, generate a random unique token. Use a public key cryptography scheme (eg. RSA) to sign the token with a private key that is kept secret to the server. Encode the unique token and the signature together using some binary-to-text scheme (eg. Base64, or just using 2-9A-KMNP-Z symbols for safer typability). The encoded combination is.

Use as demonstrated in the comment. This can be good to append to a url and store in a database, and check for in a site registration during email validation (i.e. http://site.com/register.php?connfirmationcode=2QwYbI0mf4exPi

Tahnks !!

hi, guest your code is awesome than the original one.its user friendly and we can change our key characters easily by editing $options. i prefer your code than the original one posted.

1. This function does not generate cryptographically secure values, and should not be used for cryptographic purposes. If you need a cryptographically secure value, consider using randomint, randombytes, or opensslrandompseudobytes instead.
2. Jul 15, 2018  Keygen is a PHP package that generates random character sequences known as keys. The package ships with built-in key generators for four key types namely: numeric, alphanumeric.
3. Hello everyone, What is the best way to generate unique activation keys that look like xxxx-xxxx-xxxx-xxxx where x is a hexdecimal number so for example 53e1-fbaf-4230-6c7a. I thought I could use.

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 Generate Random Token

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.
