Add chacha20-poly1305 support. This is a rebase of https://git.libssh.org/users/aris/libssh.git/log/?h=chacha20 done by fidencio.
Some additional fixes are included, to make the tests pass, to compile under Windows/Visual Studio and to make chacha20 be part of the default methods. Alberto Aguirre (7): cmake: Avoid replicating torture_pki_ed25519 target packet_crypt: Avoid setting keys every time torture_packet: Use explicit_bzero torture_packet: Set encryption/decryption keys kex: Add chacha20 to default methods chacha: Use standard types chacha: Use #pragma pack Aris Adamantiadis (11): cmake: add WITH_PACKET_DEBUG option packet: add more debugging buffer: ssh_buffer_allocate function ChaCha and Poly1305 implementations from OpenSSH cmake: detect "bounded" compiler attribute chacha: packet encryption chacha: packet decryption libgcrypt: make it compatible with chacha20 tests: test for [email protected] tests: packet encryption unit testing tests: send more packets of various sizes Jon Simons (2): pkd: add passes for [email protected] cipher pkd: move [email protected] tests to OPENSSHONLY section ConfigureChecks.cmake | 10 ++ DefineOptions.cmake | 1 + config.h.cmake | 8 ++ include/libssh/buffer.h | 1 + include/libssh/chacha.h | 44 ++++++++ include/libssh/crypto.h | 10 ++ include/libssh/libcrypto.h | 1 + include/libssh/libgcrypt.h | 1 + include/libssh/packet.h | 5 +- include/libssh/poly1305.h | 23 ++++ include/libssh/wrapper.h | 3 +- src/CMakeLists.txt | 3 + src/buffer.c | 31 ++++++ src/chachapoly.c | 160 ++++++++++++++++++++++++++++ src/dh.c | 4 + src/external/chacha.c | 216 ++++++++++++++++++++++++++++++++++++++ src/external/poly1305.c | 157 +++++++++++++++++++++++++++ src/kex.c | 10 +- src/libcrypto.c | 12 ++- src/libgcrypt.c | 15 +++ src/packet.c | 143 +++++++++++++------------ src/packet_crypt.c | 128 +++++++++++++--------- src/wrapper.c | 78 ++++++++++---- tests/client/torture_algorithms.c | 21 +++- tests/pkd/pkd_hello.c | 10 +- tests/unittests/CMakeLists.txt | 1 + tests/unittests/torture_packet.c | 205 ++++++++++++++++++++++++++++++++++++ 27 files changed, 1151 insertions(+), 150 deletions(-) create mode 100644 include/libssh/chacha.h create mode 100644 include/libssh/poly1305.h create mode 100644 src/chachapoly.c create mode 100644 src/external/chacha.c create mode 100644 src/external/poly1305.c create mode 100644 tests/unittests/torture_packet.c -- 2.14.1
