Your idea of one key only being able to decrypt something will not work. Current cryptographic programs work about this way:

There's key A and key B, you only need key A to encrypt but key A and key B to decrypt. So if you can decrypt something, you'll have both keys and therefore you'll be able to encrypt it also.

There is no crypto-algorithm that works the other way round.
