This library provides an implementation of the pEp Engine's cryptotech interface using Sequoia.

Building

Linux and MacOS

You need at least version 1.63 of rustc and cargo.

You can build this library as follows:

$ git clone https://codeberg.org/pEp/pEpEngineSequoiaBackend.git
$ cd pEpEngineSequoiaBackend
$ make
$ make install

To configure how this library is built, edit local.conf.

When built in debug mode, the library always generates trace output. If you encounter problems in release mode, you can get a trace of the library's execution by setting the PEP_TRACE environment variable.

Windows

On Windows, the Sequoia PGP backend for the pEp engine also uses the Botan backend.

Use the Visual Studio compatible Rust compiler

You can check this by trying:

C:\Users\vb\source\repos\pEpEngineSequoiaBackend> rustup show active-toolchain
1.60.0-x86_64-pc-windows-msvc (default)

Call NMake with the delivered NMakefile

C:\Users\vb\source\repos\pEpEngineSequoiaBackend> nmake /F NMakefile

To get a debug version instead of the release set environment DEBUG=debug

C:\Users\vb\source\repos\pEpEngineSequoiaBackend> nmake /F NMakefile /E DEBUG=debug

 cargo build --features crypto-cng --no-default-features

Unlike with GNU Make, DEBUG must not be defined if you want to build a release.
