# TFHE-CSPRNG
|
|
|
|
This crate contains a fast *Cryptographically Secure Pseudorandom Number Generator*, used in the
|
|
[TFHE-rs](https://crates.io/crates/tfhe) library, you can find it [here](../tfhe/) 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 instruction `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:
|
|
```shell
|
|
RUSTFLAGS="-Ctarget-cpu=native" cargo bench
|
|
```
