# Controlling the build

# Use a FIPS-validated version of boringssl.
fips = ["fips-compat", "boring-sys/fips"]

# Build with compatibility for the BoringSSL FIPS version, without enabling the
# `fips` feature itself (useful e.g. if `fips-link-precompiled` is used with an
# older BoringSSL version).
fips-compat = []

# Link with precompiled FIPS-validated `bcm.o` module.
fips-link-precompiled = ["boring-sys/fips-link-precompiled"]

# Enables Raw public key API (https://datatracker.ietf.org/doc/html/rfc7250)
# This feature is necessary in order to compile the bindings for the
# default branch of boringSSL. Alternatively, a version of boringSSL that
# implements the same feature set can be provided by setting
# `BORING_BSSL{,_FIPS}_SOURCE_PATH` and `BORING_BSSL{,_FIPS}_ASSUME_PATCHED`.
rpk = ["boring-sys/rpk"]

# Applies a 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. Alternatively, a version of boringSSL that
# implements the same feature set can be provided by setting
# `BORING_BSSL{,_FIPS}_SOURCE_PATH` and `BORING_BSSL{,_FIPS}_ASSUME_PATCHED`.
pq-experimental = ["boring-sys/pq-experimental"]

# Applies a patch to enable
# `ffi::X509_CHECK_FLAG_UNDERSCORE_WILDCARDS`. Same caveats as
# those for `pq-experimental` feature apply.
underscore-wildcards = ["boring-sys/underscore-wildcards"]

# Controlling key exchange preferences at compile time

# Choose key exchange preferences at compile time. This prevents the user from
# choosing their own preferences.
kx-safe-default = []

# Support PQ key exchange. The client will prefer classical key exchange, but
# will upgrade to PQ key exchange if requested by the server. This is the
# safest option if you don't know if the peer supports PQ key exchange. This
# feature implies "kx-safe-default".
kx-client-pq-supported = ["kx-safe-default"]

# Prefer PQ key exchange. The client will prefer PQ exchange, but fallback to
# classical key exchange if requested by the server. This is the best option if
# you know the peer supports PQ key exchange. This feature implies
