Platform Support

Pre-generated bindings

aws-lc-rs can utilize pre-generated bindings when operating on the following build targets.

² FIPS is supported but requires bindgen (no pre-generated FIPS bindings are available for Windows platforms)

Tested platforms

In addition to the platforms with pre-generated bindings listed above, aws-lc-rs CI builds and/or tests on many additional platforms. See our CI workflow configuration for the complete list of tested platforms.

Build Requirements Summary

For non-FIPS builds (aws-lc-sys):

• C/C++ Compiler: Required
• CMake: Never required
• Bindgen: Never required (universal pre-generated bindings are provided)
• Go: Never required

For FIPS builds (aws-lc-fips-sys):

• C/C++ Compiler: Required
• CMake: Always required
• Go: Always required
• Bindgen: Required unless the target has pre-generated bindings (see table above)

Bindgen for FIPS Builds

For FIPS builds on targets without pre-generated bindings, one of the following options must be used for bindings generation. See requirements page for more information.

• Enable bindgen feature in your Cargo.toml:

[dependencies]
aws-lc-rs = { version = "1", features = ["bindgen", "fips"] }

-- OR --

• Install bindgen-cli in the build environment:

cargo install --force --locked bindgen-cli
