Max Lv	503f0f1936	Include C++ headers before crypto.h in test_crypto_stream_cpp.cpp ... crypto.h defines min/max macros for the C sources; libstdc++ headers included after it fail to parse.	2026-10-14 22:53:07 +08:00
Max Lv	8cf10ba890	Do not memcpy from an empty span in the stream decoder ... An empty read before the IV arrived passed a null source to memcpy, which UBSan reports (and the ASan CI job turns into a failure).	2026-10-14 22:53:07 +08:00
Max Lv	bf5bc2f216	Include <algorithm> for std::min in test_crypto_stream_cpp.cpp	2026-10-14 22:53:07 +08:00
Max Lv	d91ef14f76	Add allocation-free C++ stream cipher codecs ... src/crypto/stream.hpp implements the legacy stream methods this build supports (AES CFB/CTR, Camellia CFB, Salsa20, ChaCha20, ChaCha20-IETF) as value types. The AES and Camellia contexts are held by value through Mbed TLS's block-cipher APIs instead of an allocated mbedtls_cipher_context_t, and the libsodium ciphers track their keystream position, finishing partial 64-byte blocks from a stack block instead of the padding copies stream.cpp makes. test_crypto_stream_cpp runs TCP streams (with fragments that split keystream blocks) and UDP packets between the C and C++ implementations in both directions for all twelve methods and checks IV replay; alloc_steady_crypto_stream requires zero allocations for new connections and packets.	2026-10-14 22:53:07 +08:00
