Howto encrypt url/uri using NGINX

Hi

Need help regarding url/uri encryption such like instead of showing real folder/files name in the website address such https://abc.com/?34kj334j33lkj43/=u83m3n434343ffgkj4545j or http://abc.com/?34kj334j33lkj43/=?!u83m3n434343ffgkj4545j

Using Nginx reverse proxy.
