The CRC checksum can't tell the difference between intentional modification
of the type you describe and data corruption; it simply knows that the
checksum doesn't match what it thinks it should be, so it presents the

When would this be useful? The public key is public, and anyone with it
could decode the message. To secure a message such that only the desired
recipient can read it, you should encrypt a message to the recipient's
public key so that only their private key can decrypt it.
Simply put, I don't understand a situation where using your system would be
an improvement over the current system, but perhaps I misunderstand

Because the key was modified in a way that GPG did not expect.

The public key can be (and is) regenerated as needed from the private key.
If you import a private key and there is no corresponding public key in the
keyring, GPG automatically recreates the public key and puts it in the
keyring. As far as I know there is no way to import only a private key
without the corresponding public key.
