Is there a way to encrypt a message with one key and decrypt it with another key

[Elwar]

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?

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

Not really the whole point, especially considering it's not the part that bitcoin uses-- non-repudiation

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