A crate to provide FFI bindings for OpenPGP and Sequoia.

This crate uses sequoia-openpgp with the crypto-rust backend, so it does not require nettle / nettle-dev system packages to build.

For the optional in-repo C smoke test (test.c), you’ll need a C compiler (e.g., gcc or clang).

• Install cbindgen: cargo install --force cbindgen.
• cargo build regenerates pgp-ffi.h automatically via build.rs.
• To run the C smoke test:
  • cargo build
  • gcc test.c -I. -L./target/debug -lpgp_ffi -o test_runner
  • LD_LIBRARY_PATH=./target/debug ./test_runner
