README

Concrete CSPRNG

This crate contains a fast Cryptographically Secure Pseudoramdon Number Generator, used in the 'concrete-core' library, you can find it here in this repo.

The implementation is based on the AES blockcipher used in CTR mode, as described in the ISO/IEC 18033-4 standard.

Two implementations are available, an accelerated one on x86_64 CPUs with the aes feature and the sse2 feature, and a pure software one that can be used on other platforms.

The crate also makes two seeders available, one needing the x86_64 feature rdseed and another one based on the Unix random device /dev/random the latter requires the user to provide a secret.

Running the benchmarks

To execute the benchmarks on an x86_64 platform:

RUSTFLAGS="-Ctarget-cpu=native" cargo bench --features=seeder_x86_64_rdseed,generator_x86_64_aesni
