bit arithmetic package to add, subtract, multiply, euclidean divide bit arrays of any size.

Uses [Uint1Array](https://npmjs.com/package/uint1array).

## get

```console
npm i --save bitmath
```

## api

```
import m from 'bitmath';
import Uint1Array from 'uint1array';

x = m.from(28);               // create bit field from number 28
y = Uint1Array.of(1,1,1);     // or just create using Uint1Array TypedArray
z = Uint1Array.of(0,1);

m.add(x,y)
m.mul(x,y)
m.div(x,y)
m.dif(x,y)                    // subtract (note: sign is omitted)
m.mod(x,y)
m.modexp(x,y,x)
```

## Timesafe Notes

Modexp using repeated squaring in a (trying to be) timesafe way is implemented.

An input argument to this GitHub Action is being exported as an environment variable. If a user of this action passes untrusted input, it could be used in an insecure manner by subsequent workflow steps.

What are GitHub Actions taint flows?

GitHub Actions: Input argument exported as environment variable

An input argument to this GitHub Action is being passed back as an output. If a user of this action passes untrusted input, it could be used in an insecure manner by consuming workflows.

GitHub Actions: Input argument passed back as output

An input argument to this GitHub Action flows into a dangerous sink (such as shell command execution). This could allow a malicious user to inject commands or exploit the action.

GitHub Actions: Input argument flows to dangerous sink

A GitHub context variable (such as issue title, PR description, or comment body) is being exported as an environment variable. These context values are user-controlled and could be exploited by subsequent workflow steps.

A GitHub context variable (such as issue title, PR description, or comment body) is being passed back as an output. These context values are user-controlled and could be exploited by consuming workflows.

GitHub Actions: GitHub context variable passed back as output

A GitHub context variable (such as issue title, PR description, or comment body) flows into a dangerous sink (such as shell command execution). This is a critical security issue that could allow command injection or code execution attacks.

GitHub Actions: GitHub context variable flows to dangerous sink

An environment variable flows into a dangerous sink (such as shell command execution). If this environment variable comes from an untrusted source, it could be exploited to inject commands.
