Implementing AWS Signature V4 for S3 uploads

[jparada]

Hi, I’m currently trying to implement AWS Signature Version 4 in Harbour to upload files to Amazon S3 (using PUT requests).

Does anyone here have experience with this implementation and could share some example code, especially for generating the canonical request, the string-to-sign, and the final signature?

I appreciate any help.

Regards,

Javier

Even better, I'll use my own implementation
