Only the recipient has the key to convert the text back into the readable message on their device..

What are the keys used by PGP?

Both the encrypted message and the short key are sent to the receiver who first uses the receiver’s private key to decrypt the short key and then uses that key to decrypt the message. PGP comes in two public key versions — Rivest-Shamir-Adleman (RSA) and Diffie-Hellman.
