This supports all the modes, suites and export mechanisms defined in RFC9180 and should be relatively easily extensible if/as new suites are added. The APIs are based on the pseudo-code from the RFC, e.g. OSS_HPKE_encap() roughly maps to SetupBaseS(). External APIs are defined in include/openssl/hpke.h and documented in doc/man3/OSSL_HPKE_CTX_new.pod. Tests (test/hpke_test.c) include verifying a number of the test vectors from the RFC as well as round-tripping for all the modes and suites. We have demonstrated interoperability with other HPKE implementations via a fork [1] that implements TLS Encrypted ClientHello (ECH) which uses HPKE. @slontis provided huge help in getting this done and this makes extensive use of the KEM handling code from his PR#19068.
