(Shameless but relevant example.) On https://CoCalc.com https://CoCalc.com [1], you can create a project and click +New-->Terminal to get an *xerm.js based terminal*, then upload the ccrypt source code (download and upload the tarball from [2]), extract it, and build it in a few seconds via "./configure && make". You can then run it via "src/ccrypt". I'm also an educator, and created CoCalc mainly for teaching (it has course management functionality).
