I have some RFC6979 test vectors, but they do not simply give me the (r,s) values before DER encoding (or so it looks?), and I haven't reached that point yet. Where could I find some (r,s) values to test against? My "expected k" values are passing tests. Perhaps the (r,s) values are in the "expected signatures" in those tests, but from my brief and naive overview, those "expected signatures" don't look like they are DER encoded, making it harder to find the (r,s) values if they are in there, and if they are not DER encoded (or are simply concatenated r,s values), they definitely are not matching my (r,s) values.

UPDATED: The simple question that should have been asked here is whether the expected signature values in the test vectors is a concatenation of the (r,s) values?

I have some RFC6979 test vectors from here, but they do not simply give me the (r,s) values before DER encoding, and I haven't reached that point yet. Where could I find some (r,s) values to test against? My "expected k" values are passing the tests.
