This is not great... we're doing pointer arithmetic on a vector's data, and using an offset based on the number of chars we need to seek into the JSON blob

Note that this code isn't actually used in production yet and wasn't referenced outside of the CryptoTest.mm file (deleted, more context on that in a separate comment)

This might be controversial, but I deleted CryptoTest.mm. My understanding is that it's failing and I didn't really have context on why, but it's been failing for a while. It looks kind of messy and I'm not sure I have the cycles right now to fix it, and I don't want to block monthly goals on it. Open to creating a follow-up task if people want to keep this test around
