Add sentinel the ability to randomly generate key for the "manual insertion" mode. — Sentinel shall require a public key, and encrypt the response with that public key before delivering it (for added security) — the owner of the private key then can decrypt the result — we can also write a helper binary for that

The "encrypt with public key" is a by-product of one of our design decisions:

• Sentinel will never expose any sensitive data in plaintext.

The second design decision is the fact that sentinel is the only interaction point for the Operator. The Operator cannot directly talk to Aegis Safe.
