php-mcrypt 3:1.0.5-4ubuntu1 (amd64 binary) in ubuntu noble

 These functions provides bindings for the unmaintained libmcrypt library.
 .
 The extension is unbundled from php-src as of PHP 7.2.0, because the underlying
 libmcrypt has obviously been abandoned. It is recommended to reevaluate using
 this extension.
 .
 This is empty package that depends on default PHP version.
