Updated S3 for CertMagic Storage

This library allows you to use any S3-compatible provider as key/certificate storage backend for your Certmagic-enabled HTTPS server. To protect your keys from unwanted attention, client-side encryption using secretbox is possible.

See example/ for an exemplary integration.

What is a S3-compatible service?

In the current state, any service must support the following:

• v4 Signatures
• HTTPS
• A few basic operations:
  • Bucket Exists
  • Get Object
  • Put Object
  • Remove Object
  • Stat Object
  • List Objects

Known good providers/software:
