We would like to thank the CrypTool team for having put together the CrypTool-Online website, especially for the password checker and password generator. With permission from your team we integrated these functions into our internal corporate security web site. This helps our users to better understand in detail what kind of passwords are good and qualify for usage. We'd like to mention that it was easy to customize the scripts to reflect our internal password policy, which helped us to adopt the tool to real life. We hope this encourages your students to continue their path of providing useful tools and solutions.

The website CryptoPrograms http://www.cryptoprograms.com is dedicated to create and solve classical ciphers online.
