Doesn't look like it's there:$ openssl3 version OpenSSL 3.0.0-dev xx XXX xxxx (Library: OpenSSL 3.0.0-dev xx XXX xxxx) $ echo -n "hello" | openssl3 dgst -blake2b512 BLAKE2b512(stdin)= e4cfa39a3d37be31c59609e807970799caa68a19bfaa15135f165085e01d41a65ba1e1b146aeb6bd0092b49eac214c103ccfa3a365954bbbe52f74a2b3620c94 $ echo -n "hello" | openssl3 dgst -blake2b512 -mac blake2bmac -macopt key:secret Algorithm blake2bmac not found $ Besides, how does one print a list of supported MAC algorithms?
