Feature request - general encryption utilities

As a builder of dev tools dealing with sensitive data (see dmno.dev), sometimes I need to encrypt/decrypt arbitrary data in a local cache. Currently I have to store a key somewhere, which is usually a file sitting somewhere else on disk - obviously not that secure...

It would be really cool if I could rely on the user's local 1Password app for that instead.

I would imagine this would look like the CLI and SDK (eventually) providing arbitrary `encrypt` and `decrypt` methods, which interact with the user's local 1password application. The existing biometric auth and locl/unlock mechanisms would mean I'd get encryption without storing a key locally and so the user would have to periodically re-prove their identity.
