https://www.openssl.org/docs/manmaster/man1/openssl-passwd.html says in Description:

The MD5-based BSD password algorithm -1, its Apache variant -apr1, and its AIX variant are available.

I almost stopped reading there because I wanted SHA512. The Options section lists -5 and -6; these should also be in Description's summary.

Or better still, get rid of that line as it's duplicating Options by not only listing the algorithms but giving their options too.
