The command simply decomy readable format. GPG will show not only the contents of the original me s the file nto its orginal ge but also the digial signature verification. Because there is not necessarlly any encryption on a digitally signed message, the recelver does not need the sender’s public Key in his keyring to view the contents with the -decrypt command. Remember, though, without the key,the receiver would not be able o verify the signature. If Matthew sent a signed message to Roger i return, he would 5ign the message with his private key. Upon receipt of the signed message, Roger could verify the signature against Matthew's public key, provided he had already Imported the key. 7. Make a screen capture showing the contents of the digitally signed message. Note: This concludes Section 1 of the lab @ awe wOEE®E B ~raGee oMo
