consistenttime

#constanttime

Documentation

A crate that supports many constant time operations. The reference is Go-Lang's crypto/subtile which implements the orginal form of these constant time operations. I took the library of extrapolating the uint8 and uint32 into all Rust integer types.

These operations are not designed to be fast. They are designed to take the same if they suceeded or fail. This is to prevent side channel attacks on cryptographic libraries and applications.

This crate is core only. So it does not require std therefore it can be used without an operating system for OS and Embedded Development.

To use this crate include:

[dependencies]
constanttime = "0.2"

#Audit

Does this crate work as advertised?

I'd sure like to find out! If you know asm, or a lot about low level machine hacking I'd love your help.
