request: info about ripemd160 MAC

[bjmgeek]

I am seeing some traffic trying to log into my server using MACs hmac-ripemd160 or hmac-ripemd160@openssh.com. I was hoping you could add some info about these MACs.

thanks!

FYI, this Kex Algorithm was removed in OpenSSH 7.6 (released 2017-10-03). Therefore I see no reason to expand upon it in the document.

You can, however, find more about it in other sources on the net:

• RIPEMD is defined in ISO/IEC 10118-3:2004 @ iso.org, paywalled
• RIPEMD @ wikipedia.org
• HMAC RFC2104 @ ietf.org
