The reason for having a "secret key" is because I want to separate Shopify account passwords with Ronin secret keys.

That way, if Shopify is hacked, then Ronin is unaffected. If Ronin is hacked, then Shopify credit card information is protected.

Ronin is currently using Sha256 encryption for your secret key.

Soon we will have a secure way to change your secret key, then we can have even more security.
