EscherRuby - HTTP request signing lib [![Build Status](https://img.shields.io/github/actions/workflow/status/emartech/escher-ruby/ruby.yml?branch=master)](https://github.com/emartech/escher-ruby/actions/workflows/ruby.yml)
=====================================

Escher helps you creating secure HTTP requests (for APIs) by signing HTTP(s) requests. It's both a server side and client side implementation. The status is work in progress.

The algorithm is based on [Amazon's _AWS Signature Version 4_](http://docs.aws.amazon.com/AmazonS3/latest/API/sig-v4-authenticating-requests.html), but we have generalized and extended it.

More details will be available at our [documentation site](http://escherauth.io/).

Check out a [working example] (https://github.com/emartech/escher-ruby-example).

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.

GitHub Actions: GitHub context variable exported as environment variable

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.
