Obviously, rust-openssl relies on the system's OpenSSL library, and the wasm compilation platform is not sure if it exists. You can find the information here. Crates like sha256 may solve your problem.

[Skepfyr]

Getting OpenSSL to compile for wasm looks like it might be possible but you're definitely going to have to play around with this yourself (probably by forking openssl-src), I haven't found all that many people doing it so you're likely treading new ground. As @thy4862 says you may find it easier to use pure Rust libraries and not try and link to OpenSSL.

I'm closing this in favour of #1016.
