Re: Surely the point of encryption...

If you want to prevent tampering, you need to use signatures.

You need to provide data integrity against active attacks. Signatures are one primitive for that, but they're generally not appropriate for this use case. HMAC and similar constructs, using cryptographic digests but not asymmetric cryptography, are more plausible.
