It'd help if I gave the correct reference: RFC 8314.

Currently my choice seems to be between trying to
algorithmically munge the name returned by
   gnutls_cipher_suite_get_name()
[complex enough that I doubt I'd do it without errors]

or duplicating the IANA tables for lookup from the
"value" pair.  But there's no obvious way to get that
pair either.

Could the cs_algorithms[] table in lib/algorithms/ciphersuites.c
be extended with an IANA name field, and an API provided?
