Magento provider no longer works (outdated hash algorithm)

[jeyoor]

The Magento provider is throwing errors for me when I attempt to use it with version 2.4.6

The error is

HTTP 400: Signature method HMAC-SHA1 is not supported

From looking at the developer docucmentation, it appears that newer versions of Magento require HMAC-SHA256.

I've already finished the new interface , but since iam not a contributor yet of this repo, i have to provide full test cases before i can make a pull request for this. I'm under pressure to finish my project, and then i'll be able to provide such implementation.
