coil-crypto
Userland cryptography for coil. RustCrypto lives in a cdylib (libcrypto.so / .dylib / .dll) plus Coil wrappers. use crypto::{…} is this package, not a compiler builtin.
Layout#
| Path | Role |
|---|---|
src/crypto.hy | Package exports (sha256, init / update / finalize, HMAC, AEAD, Ed25519 / X25519, Argon2id, ct_eq) |
native/ | Rust cdylib, C ABI coil_crypto_* |
coil.toml | spool manifest ([package] name = "crypto"); coil does not read it |
extern "crypto" / dload("crypto") resolves to libcrypto.so in native/ (--ffi-search-path ./native; spool passes it from [ffi] search_paths). Hasher state is an opaque pointer in the .so (Object::CryptoHasher is gone). Hasher.drop calls coil_crypto_hasher_free.
Build#
make # native/libcrypto.{so,dylib,dll}
make test # cargo test in native/Or:
cd native && cargo test && cargo build --release
# copy libcrypto.so / .dylib / crypto.dll into native/ (the FFI search path)Argon2id MVP params are fixed (19 MiB, 2 iterations, parallelism 1) and not caller-tunable.
