No. user_1, user_2 and user_3 each generate their own public-private keypair. So: Receiver_1 has public_key_1 and private_key_1 Receiver_2 has public_key_2 and private_key_2 Receiver_3 has public_key_3 and private_key_3 They then all send their public keys to a fourth user, "Sender" (who may actually be one of the receivers, if you wish). Sender then encrypts the file using the public keys of all the Receivers. For example: gpg --recipient Receiver_1 \ --recipient Reciever_2 \ --recipient Receiver_3 \ --encrypt-file file_to_be_encrypted Each of the three recipients will then be able to decrypt the file using their own private key.
