ring-compatible crypto library using the cryptographic operations provided by AWS-LC.
Allows implementation to allocate values of arbitrary size. (The meaning of this feature differs
from the "alloc" feature of ring.) Currently, this is required by the io::writer module.
Enable feature to access the io module.
Enable feature to preserve compatibility with ring's signature::VerificationAlgorithm::verify
function. This adds a requirement on untrusted = "0.7.1".
EXPERIMENTAL Enable this feature to have aws-lc-rs use the aws-lc-fips-sys crate for the cryptographic implementations. The aws-lc-fips-sys crate provides bindings to the FIPS variant of AWS-LC. AWS-LC has been submitted to an accredited lab for FIPS validation testing, and upon completion will be submitted to NIST for certification. Once NIST grants a validation certificate to AWS-LC, we will make an announcement to Rust developers on how to leverage the FIPS mode.
Performs an "address sanitizer" build. This can be used to help detect memory leaks. See the "Address Sanitizer" section of the Rust Unstable Book.
Although this library attempts to be fully compatible with ring, there are a few places where our behavior is observably different.
std library. We currently do not support a
#![no_std] build.aws-lc-sys. We currently support Mac
and Linux, both x86-64 and aarch64.Ed25519KeyPair::from_pkcs8 and Ed25519KeyPair::from_pkcs8_maybe_unchecked both support
parsing of v1 or v2 PKCS#8 documents. If a v2 encoded key is provided to either function,
public key component, if present, will be verified to match the one derived from the encoded
private key.Rust developers increasingly need to deploy applications that meet US and Canadian government cryptographic requirements. We evaluated how to deliver FIPS validated cryptography in idiomatic and performant Rust, built around our AWS-LC offering. We found that the popular ring (v0.16) library fulfilled much of the cryptographic needs in the Rust community, but it did not meet the needs of developers with FIPS requirements. Our intention is to contribute a drop-in replacement for ring that provides FIPS support and is compatible with the ring API. Rust developers with prescribed cryptographic requirements can seamlessly integrate aws-lc-rs into their applications and deploy them into AWS Regions.
We use GitHub Issues for managing feature requests, bug reports, or questions about aws-lc-rs API usage.
Otherwise, if you think you might have found a security impacting issue, please instead follow our Security Notification Process below.
If you discover a potential security issue in AWS-LC or aws-lc-rs, we ask that you notify AWS Security via our vulnerability reporting page. Please do not create a public GitHub issue.
If you package or distribute aws-lc-rs, or use aws-lc-rs as part of a large multi-user service, you may be eligible for pre-notification of future aws-lc-rs releases. Please contact aws-lc-pre-notifications@amazon.com.
