Public-key Security - Demo

This assistant lets you encrypt PDF documents based on Public Key Certificates - also called certificate based encryption - in pure PHP.

For demonstration purposes, one recipient certificate is fixed. You have to install its private key on your machine which is available as .pem or as .pfx (password is "setapdf").

Select or upload a file

The uploaded files are bound to your browser session and are not accessible by any other user. They will get deleted after 24 hours automatically.
