HPKE Examples

Demonstrates HPKE (Hybrid Public Key Encryption, RFC 9180): public-key encryption built from a key encapsulation mechanism (KEM), a key derivation function (KDF), and an authenticated cipher (AEAD).

To build wolfSSL for these examples run ./configure --enable-hpke --enable-aesgcm --enable-curve25519 --enable-ecc && make && sudo make install

• hpke_test.c - one-shot seal/open (wc_HpkeSealBase() / wc_HpkeOpenBase()) with all supported KEM/KDF/AEAD combinations.
• hpke_context.c - seal/open contexts (wc_HpkeInitSealContext() / wc_HpkeContextSealBase() and the open equivalents): one key encapsulation protecting an ordered sequence of messages.
