yes. The other half is sign with one key, verify with another.

That's basically the whole point of public key crypto.

Is it possible to have two paired keys such that I encrypt a message with one key, then later decrypt that same message with a different key?
I basically am looking to encrypt a message on a server, the server then releases the encrypted message.
Then later, the key to decrypt the message will be released.
But I am just trying to play it safe as far as storing or transferring the key used to encrypt the message in the first place. I would rather just immediately discard it once the message is created and hold the second key in cold storage until it is time to release it.
Any thoughts?
