I'm trying to create a Video Hosting site, for that I started checking all existing sites like that one to see how they work and how they secure their files. For my surprise, I noticed most "video streaming websites" not only work the same way but also have exactly the same "url encoding" for restricting their files according to "File name / Remote IP Address / Time Expiration"...
I also notice that all of them work with NGINX and even old versions (1.2.9)...

All their links look like this:

http://some-server.com/6hv743pcesoax3ptxziinrn5wd5fwgxpr63zwur3eqfgsrd6xjog4nyvke/video.mp4

The ENCODING this link uses is not "MD5" or even "BASE64" and all NGINX modules specify (so this is what confuses me a lot)...

All this sites encode their links in a format which includes only "a-z" letters and "2-7" numbers... according to my knowledge this links are in BASE32... and I can't find any method or module in NGINX to create my links the same way...

6hv743pcesoax3ptxziinrn5wd5fwgxpr63zwur3eqfgsrd6xjog4nyvke

58 chars (weird, MD5 uses 32)...

Did all those sites use the same method? Or were all those sites made by the same owner/person?

The thing is that I wanna know how to create in NGINX the same looking HASH link in BASE32 (not in MD5, not BASE64 and not any other encoding)... BASE32!
