OpenSSL speed command for HMAC

Question

OpenSSL provides a convenient command for benchmarking algorithms.

From what I understood, it only allows benchmarking encryption and hash functions. Is there a way to benchmark HMAC as well (say, hmac-sha256) from command line?

Posting an updated answer as I was just looking at this myself!

From OpenSSL 3.0.0 the speed utility has been updated to include the -hmac option, so you can benchmark hmac with a digest of choice:

% openssl speed -hmac sha256
Doing hmac(sha256) for 3s on 16 size blocks: 8128050 hmac(sha256)'s in 2.99s
Doing hmac(sha256) for 3s on 64 size blocks: 6008552 hmac(sha256)'s in 2.99s
Doing hmac(sha256) for 3s on 256 size blocks: 3546506 hmac(sha256)'s in 2.99s
