Security

This module allows an administrator to define a date on which to expire a specific user account or to define a period at a role level where inactive accounts will be locked.

This module uses the jCryption plugin (http://www.jcryption.org version 1.2 only) to encrypt any form submission in Drupal using 265-bit public/private key encryption. For example, you can use it to encrypt the login and registration form, so a user's passwords are never transmitted in clear text. This is similar to how SSL works to encrypt traffic.

The http_reject module looks at the HTTP request being sent to your Drupal instance and will reject it if set criteria are met.

The OAuth2 module is under active development, for more info check out our plan: https://www.drupal.org/project/oauth2/

BOTCHA is a highly configurable non-CAPTCHA spam protection framework.

In CAPTCHA, user has to prove he/she is human. Unfortunately, spambots learned
to bypass CAPTCHA really well, and real users are frustrated with increasing
complexity and burden of CAPTCHA.

In BOTCHA, we don't abuse our human users - BOTCHA protection is completely
transparent to them and non-intrusive.

BOTCHA lets spambots to prove they are bots, and let real users zip by.

BOTCHA is useful for any form that has to be protected from spambots.

BOTCHA always works as designed - guaranteed! All of BOTCHA recipes are covered by Selenium-tests and we have our own "TestSwarm" to do testing as often as possible: see #1894478: The latest Selenium-tests launches & reports for details.
