vartime Safety - guardrails & static analysis by design

1

Some algorithms have vartime components on non-secret data requiring associated use of vartime functionality. e.g. where the vartime use is associated with non-secret dependant data. This could be treated similarly...

Support for creating `BoxedMontyParams` from `ConstMontyParams`

3

Version: `0.6.0-pre.12`. I am trying to define pre-computed SSH DH groups 1 and 14-18 parameters using `ConstMontyParams` because groups 15-18 take a long time to compute--more than 5s (debug) for...

Estimated precision for MULT product & input handling to prevent overflow ?

1

Hello - just learning to use this library + handle the fixed precision and initialize correctly I think :) Let's say per [NIST.SP.800-56Br2](https://nvlpubs.nist.gov/nistpubs/SpecialPublications/NIST.SP.800-56Br2.pdf) - Appendix C.2 - Deterministic Prime-Factor Recovery...

Easier working with native numbers

In my usage with `BoxedUint` I am really missing comparison and calculations with `u32` and `u64` at least, currently it is quite inefficient as I have to do the following...

impl_modulus! is unusable for bigints starting from U3072

6

## Description When using the `impl_modulus!` macro with U3072 and bigger types, the `R2` constant computation takes several seconds. The Rust compilers version >= 1.73 with an error. In some...

Optimized assembly acceleration

Though we should definitely maintain a baseline profile which is pure Rust, it would be nice to be able to leverage optimized assembly implementations, and ideally formally verified ones which...
