The purpose of this project is to make it possible to uninstall the mcrypt extension without breaking things.

• Disable ext_mcrypt and start working on implementing the functions in src/mcrypt.php
• Do NOT write your own crypto. Ever.
  • https://github.com/phpseclib/phpseclib supports everything needed (recommend ext_openssl for speed in some cases)
• Don't edit the existing tests, but feel free to add new ones.
• A PR that increases the number of failing tests will not be merged until the number of passing tests increases or stays the same.

Coming soon.

• mcrypt hasn't been maintained since 2003
• We shouldn't depend on unmaintained crypto code
• Having a userspace polyfill makes it easier for the PHP core team to drop ext_mcrypt
