Blake2b with key

[Blumenthal, Uri - 0553 - MITLL]

Answered my own questions:

$ openssl3 list -mac-algorithms
Provided MACs:
  BLAKE2bMAC @ default
  BLAKE2sMAC @ default
  CMAC @ default
  GMAC @ default
  HMAC @ default
  KMAC128 @ default
  KMAC256 @ default
  Poly1305 @ default
  SipHash @ default
$
$ echo -n "hello" | openssl3 mac -macopt key:secret blake2bmac

    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?
