Generating Ed25519 key/pair with LibreSSL on mac: missing algorithm

Question

I am trying to generate a Ed25519 key/pair using

openssl genpkey -algorithm Ed25519 -out ed25519key.pem   

However, on my MacOS I get this:

Algorithm Ed25519 not found

I am running OpenSSL / LibreSSL 3.2.5 but I have no idea why this algorithm wouldn't be available.

Is there something I'm missing / need to install?

Answer 1

It seems that the default OpenSSL (LibreSSL) that comes with MacOS (even in MacOS 11.2.3) simply doesn't have the algorithm.

I installed OpenSSL 1.1.1k via brew separately (in /usr/local/opt/[email protected] ) and using that binary the command works.
