- usda.gov/DS (alg 8, id 20536): DNSSEC specification prohibits signing with DS records that use digest algorithm 1 (SHA-1). See RFC 8624, Sec. 3.2.

- usda.gov/DS (alg 8, id 20536): DS records with digest type 1 (SHA-1) are ignored when DS records with digest type 2 (SHA-256) exist in the same RRset. See RFC 4509, Sec. 3.
