For other cryptographic operations, almost any sufficiently large prime can be used. Even a 50% reduction on a computation that will take trillions of years, has no practical impact.
One could create an account, hail rides and add their own payment method while still being associated with someone else's email. Ride recipes would then be sent to someone else's email where the receiving party could add or increase a tip through an unauthenticated link and have it charged to the riders credit card.
I have upgraded my brew install, but am unsure of what to do with the vulnerable system install.
That would be a cryptographic hash you are describing. Not all hash functions share that property. As long as arbitrary input is mapped to a fixed size output it is a hash function. For example see NeuralHash [1] which is a hash function designed to be "insensitive to small changes in the input image."
