In the programming language I’m working on, MethodScript, I’ve created a subclass of string, secure_string. The normal print value is “secure string”. Unlike somewhat equivalent classes in other languages, this is a subclass of string, which means it can be passed around opaquely to things that only accept strings, but then the functions that actually need to be aware of secrets can check for the subclass and call the special decryption method. The string is encrypted in memory, but this is really just obscurity, because the decryption key is there too. But it does prevent most logging from ever leaking the secret, including things like memory dumps. I wish mainstream languages had a feature like this, since MethodScript is still fairly far in the “toy” category for now.
