Decrypt emxc:// files from matrix and show their content in the browser

matrix-decryptapp

Matrix Decryptapp is a simple client-side web app that can decrypt encrypted matrix URIs (emxc://...) entirely in the browser, then display the resulting blob in an iframe.

This is useful for non-web clients like Weechat which cannot otherwise display encrypted images without using an external script.

Usage

Weechat

This trigger replaces all emxc:// URLs to use an instance of this app hosted on https://seirl.github.io/ :

/trigger addreplace emxc_decrypt modifier weechat_print "" ";($|[^\w/#:\[])(emxc://([^ ]+));${re:1}https://seirl.github.io/matrix-decryptapp/#${re:2};"

If you do not trust this website to keep your encrypted URIs secure, the URL in the trigger can be replaced by your own deployment of this static website.
