AWS HTTPS access with access key / secret

[mjmottram]

Hi,

I see there are posts already regarding AWS S3 access, however, I cant find any that explain how I can use AWS access key and secret combinations in a C program (i.e. on the ESP32, not Arduino code) to authenticate with the S3 server.

Currently, I'm able to read data from public buckets, but not private buckets. We have data uploads that use libRockFillAndSign (https://github.com/forrestcavalier/librockFillAndSign) to calculate and insert the authentication headers, but are relying on this and have yet to figure out how to make it work for GET requests.

I can't see anything there, but was wondering whether there's something in the ESP-IDF that might be able to do this for us?

Thanks,
Matt
