Since I’ve been having lots of visits in my wxWidgets version of the Celsius to Fahrenheit converter, I’ve decided to prepare an online javascript version which lets you easily make the conversion.

Celsius:

PHP random password generator

Published on July 23, 2009 in Online Tools. Closed Tags: , , , , , , , , , .

As a new sequel to the Excel random password generator and the Random password generator, I’ve made a PHP random password generator service…

You can call it this way (if you hover the parameter values, you’ll get an explanation):

http://www.neoegm.com/services/random_password.php?length=8&upper=1&lower=1&numbers=1

So, for example, to generate a 10 characters numeric password you could access:
