On Elixir Discord there was discussion about a library that would provide data signing in standardised way. So I have implemented SSH signing using just Erlang/OTP (no external dependencies). It supports RSA and Ed25519 signing currently. I plan to submit that to the OTP to include that in SSH application for broader audience, but right now it lives as separate library (not yet published on Hex).
