- Nov 11, 2017 This is an article which is specifically written to generate key used in a Laravel web-based application project. The key generated is very special for several features which is needed by the Laravel web-based application itself.
- This will generate a random string with the length of 10 chars. Of course, some might say it's a bit more heavy on the computation side, but nowadays processors are optimized to run md5 or sha256 algorithm very quickly. And of course, if the rand function returns the same value, the result will be the same.
Generate Serial numbers. This tool can generate up to 250,000 unique random codes at a time. Not logged in, it's limited to 1000 codes per batch. If you own a Random Code Generator account, it can generate an unlimited amount of codes in batches of 250.000 each! The generated codes can be used for passwords, promotional codes, sweepstakes, serial numbers and much more. Sep 07, 2016 Generate a random string of specified length.

This is a short guide on how to generate a random token with PHP. These kind of tokens are used for a number of different reasons:

- To protect against Cross-Site Request Forgery. These are often referred to as CSRF tokens.
- To help verify a user’s email address. i.e. You send the user’s email address a link that contains a “random” token in the URL and when they click on it, you compare the token that they’ve given you with the token that you’ve stored against their user account. If the tokens match, you assume that the given email address is correct.
- To generate a “Forgot Password” request (typically, it uses the same method as the one outlined above).
A lot of people make the mistake of using the function rand or mt_rand in correlation with a hashing function such as md5 or sha1:
The problem with the approach above is that the token will NOT be cryptographically secure.
To generate a cryptographically secure token in PHP, you will need to use the openssl_random_pseudo_bytes function:
