In my view, ARC, as an "Experimental Status" (and still in design) proposal *should* include support for all valid DKIM STD hashing methods, including rsa-hash1, and I agree, should not be the impetus for removing sha1 support in DKIM implementations. Until a DKIM implementation is "ready" to

ARC inherits all the DKIM mechanisms by reference. So whatever’s valid for DKIM (the list you provided) is what’s valid for ARC. On Tue, Oct 23, 2018 at 03:58 Scott Kitterman wrote: > I've started looking at updating dkimpy to align to the current versions > of > the specification. > > Last time

I've started looking at updating dkimpy to align to the current versions of the specification. Last time I looked at this particular issue, ARC could use any algorithm that DKIM uses. As I recall, that was once of the stimuli for the DCRUP working group (to avoid having rsa-sha1 be valid for A
