Cargo Features

rboring-sys has no features set by default.

[dependencies]
rboring-sys = { version = "4.11.1", features = ["fips", "fips-link-precompiled", "rpk", "pq-experimental", "underscore-wildcards"] }
fips

Use a FIPS-validated version of boringssl.

Link with precompiled FIPS-validated bcm.o module.

rpk

Enables Raw public key API (https://datatracker.ietf.org/doc/html/rfc7250)

pq-experimental

Applies a patch (patches/boring-pq.patch) to the boringSSL source code that enables support for PQ key exchange. This feature is necessary in order to compile the bindings for the default branch of boringSSL (deps/boringssl). Alternatively, a version of boringSSL that implements the same feature set can be provided by setting BORING_BSSL{,_FIPS}_SOURCE_PATH.

underscore-wildcards

Applies a patch (patches/underscore-wildcards.patch) to enable ffi::X509_CHECK_FLAG_UNDERSCORE_WILDCARDS. Same caveats as those for pq-experimental feature apply.
