[Feature request] - Change mining key encryption type

[Tr43212]

Description:
Replaces Base64 encoding with SHA-256 hashing for enhanced security.

Implementation Details:
Replace "base64" module with "hashlib" module.

Reason for Change:
Base64 is not secure, while SHA-256 provides a secure, non-reversible hash suitable for sensitive data.

Cons:
Make the users enter the mining key everytime they want to start a new mining sesssion

A hash is unsuited for this application. An encryption standard would be a better fit.

I think OP is referring to the mining key encryption where the encrypted key is stored in Settings.cfg by python miner

Still, a hash is unsuited. If you have to re-enter the mining key with every start anyway, why even save it?
