The C code is automatically derived from the (verified) [original implementation](https://github.com/project-everest/hacl-star/tree/master/code/curve25519) in the [F* language](https://github.com/fstarlang/fstar) by [KreMLin](https://github.com/fstarlang/kremlin). In addition to the improved safety and security of the implementation, it is also significantly faster than the default implementation of Curve25519 in mbedTLS. + +The caveat is that not all platforms are supported, although the version in `everest/library/legacy` should work on most systems. The main issue is that some platforms do not provide a 128-bit integer type and KreMLin therefore has to use additional (also verified) code to simulate them, resulting in less of a performance gain overall. Explictly supported platforms are currently `x86` and `x86_64` using gcc or clang, and Visual C (2010 and later). diff --git a/lib/mbedtls-2.27.0/3rdparty/everest/include/everest/Hacl_Curve25519.h b/lib/mbedtls-2.27.0/3rdparty/everest/include/everest/Hacl_Curve25519.h new file mode 100644 index 0000000..e3f5ba4 --- /dev/null +++ b/lib/mbedtls-2.27.0/3rdparty/everest/include/everest/Hacl_Curve25519.h @@ -0,0 +1,21 @@ +/* Copyright (c) INRIA and Microsoft Corporation.
