ctcrypto
This is an attempt to port some of Go's standard cryptography to use
the safenum library. That library
provides an alternative to Go's big.Int type, attempting to operate without
timing leaks. This makes it more suitable for cryptography compared to big.Int,
which is unfortunately used pervasively throughout Go's standard cryptography routines.
The code in this repository is based on Go's standard crypto package, trying
to make minimal changes to use safenum.Nat instead of big.Int. This isn't
an attempt to make a useable cryptography library, but rather to see how useable
safenum.Nat's API would be for replacing big.Int, and producing benchmarks
to see how much this switch to constant-time operation impacts real-world workloads.
This is experimental software, use at your own peril.
(Really, this library isn't intended for consumption, unlike safenum)
