RFC 4398, Storing Certificates in DNS, November 1987


[2.2](https://datatracker.ietf.org/doc/html/rfc4398#section-2.2).  Text Representation of CERT RRs

   The RDATA portion of a CERT RR has the type field as an unsigned
   decimal integer or as a mnemonic symbol as listed in [Section 2.1](https://datatracker.ietf.org/doc/html/rfc4398#section-2.1),
   above.

   The key tag field is represented as an unsigned decimal integer.

   The algorithm field is represented as an unsigned decimal integer or
   a mnemonic symbol as listed in [[12](https://datatracker.ietf.org/doc/html/rfc4398#ref-12)].

https://tools.ietf.org/html/rfc4034#appendix-A.1

[A.1](https://datatracker.ietf.org/doc/html/rfc4034#appendix-A.1).  DNSSEC Algorithm Types

   The DNSKEY, RRSIG, and DS RRs use an 8-bit number to identify the
   security algorithm being used.  These values are stored in the
   "Algorithm number" field in the resource record RDATA.

   Some algorithms are usable only for zone signing (DNSSEC), some only
   for transaction security mechanisms (SIG(0) and TSIG), and some for
   both.  Those usable for zone signing may appear in DNSKEY, RRSIG, and
   DS RRs.  Those usable for transaction security would be present in
   SIG(0) and KEY RRs, as described in [RFC2931].
