# Crypto++ vendoring notes
|
|
|
|
- Upstream version: Crypto++ 8.9.0
|
|
- Upstream tag: `CRYPTOPP_8_9_0`
|
|
- Upstream commit: `843d74c7c97f9e19a615b8ff3c0ca06599ca501b`
|
|
- Source: <https://github.com/weidai11/cryptopp>
|
|
|
|
The top-level source distribution is vendored for disconnected builds. CMake
|
|
excludes upstream test programs, assembly, and algorithm-specific SIMD units.
|
|
|
|
WiiCompiled carries three small portability adaptations for its supported
|
|
Clang/MSVC-ABI build:
|
|
|
|
1. `config_os.h` has a project-scoped opt-in around Crypto++ 8.9.0's Clang/MSVC
|
|
hard stop.
|
|
2. `config_int.h` can avoid Clang's 128-bit division helpers, which are absent
|
|
from this ABI's runtime library.
|
|
3. `cpu.cpp` returns inert feature-probe results when `CRYPTOPP_DISABLE_ASM` is
|
|
set, avoiding references to the deliberately omitted x64 assembly helpers.
|
|
|
|
This configuration supplies SHA-1, sect233r1 public key derivation, ECDSA
|
|
signing, signature verification, and key validation for the runtime's Wii ES
|
|
crypto implementation.
