This project provides configuration snippets to configure HAProxy to act as an authenticating gateway for to AWS S3 or another S3 compatible service. This allows you to proxy a private S3 bucket without requiring users to authenticate to it.

s3v2 backend implements s3v2 signature using pure HAProxy configuration.

s3v4 backend implements s3v4 signature using pure HAProxy configuration.

s3v2-lua & s3v4-lua implements s3v2 & s3v4 signature in lua, using HAProxy primitives (ie. converters) for cryptography.

It provides the same features as the pure HAProxy configuration implementation.
