            Bug ID: 2715
           Summary: for more flexibility, please support a comma ','
                    separated list of patterns to add to/remove from the
                    defaults
           Product: Portable OpenSSH
           Version: 7.5p1
          Hardware: Other
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P5
         Component: sshd

What I'm thinking of would look like this:

Macs=-umac-64*,-hmac-sha1*

By accident, I just discovered a list of this form:

Macs=-umac-64*,hmac-sha1*

is supported (the '-' operates on the whole list).

This form:

Macs=-umac-64*,-hmac-sha1*

('-' in front of each pattern) is not supported.

Ideally, a mix like this:

Macs=-umac-64*,+foo*,-hmac-sha1*

offers the best flexibility, IMO.


Cheers,

I don't think extra flexibility is worth the complexity needed to
implement it. If you have a need to select algorithms that goes beyond
simply adding or removing some from the default set then it's easy just
to specify the list.
