Task 4: Generate Keypairs 1. The following command is used to create new primary keypair: gpg --full-generate-key As you see from the output of the above command, GnuPG can create different types of keypairs. The primary pair is used make signature operations, whereas the second pair is used for encrypting. The different choices proposed by the gpg are the following: Choice 1: It allows to create two RSA keypairs, the first keypair is used for signature and the second one for encryption. Choice 2: It allows to create two keypairs, the first one is DSA used for signature and the second one is Elgamal is used for encryption. - what are the other three choices? 2. Type 1 to select choice 1 and press Enter 3. For the Key size: The longer the key, the more resistant it will be against an attack, but it requires a longer processing time. We currently consider that 2048 bits is a minimum to have security for a few years. Type 2048 and press Enter 4. For the expiration Date: It must be chosen with care, because it is difficult to send the key with the updated date to users who already have your expired public key. For this lab, type 0 and press Enter, then type Yto confirm
