Summary

Analyze keywords

Allows your browser to access resources that require AWS Sigv4 signatures.

Inspired by carsales/aws-request-signer.

Main differences from carsales/aws-request-signer:

They basically rolled their own signature process vs I rely on mhart's excellent libraries. In Firefox (and presumably elsewhere) I use mhart/aws4fetch to handle all heavy lifting. This has the perk of using the browser's WebCrypto API, which should be insanely faster. In Chrome I use mhart/aws4 because Chrome still has zero async support for webRequest.onBeforeSendHeaders.
This extension triggers on all AWS services instead of filtering for one.
Instance Profile credentials aren't supported as I have no use for them but could be added fairly trivially.
Chrome/Firefox/Opera support.

Safety

Risk impact

AWS Agent is risky to use as it requires a number of sensitive permissions that can potentially harm your browser and steal your data. Exercise caution when installing this extension. Review carefully before installing. We recommend that you only install AWS Agent if you trust the publisher.
