c534c08710[test/crypto] Add FSChaCha20Poly1305 AEAD python implementation (stratospher)c2a458f1c2[test/crypto] Add FSChaCha20 python implementation (stratospher)c4ea5f6288[test/crypto] Add RFC 8439's ChaCha20Poly1305 AEAD (stratospher)9fc6e0355e[test/crypto] Add Poly1305 python implementation (stratospher)fec2ca6c9a[test/crypto] Use chacha20_block function in `data_to_num3072` (stratospher)0cde60da3a[test/crypto] Add ChaCha20 python implementation (stratospher)69d3f50ab6[test/crypto] Add HMAC-based Key Derivation Function (HKDF) (stratospher)08a4a56cbc[test] Move test framework crypto functions to crypto/ (stratospher) Pull request description: split off from #24748 to keep commits related to cryptography and functional test framework changes separate. This PR adds python implementation and unit tests for HKDF, ChaCha20, Poly1305, ChaCha20Poly1305 AEAD, FSChaCha20 and FSChaCha20Poly1305 AEAD. They're based oncc177ab7bc/bip-0324/reference.pyfor easy review.
