Bob Decrypts Alice's Digital Signature Which Key He Used
He then hashes the message using the same hash function that Alice used and compares the result to the message digest that he recovered from Alices signature. He then using the digital signature algorithm decrypts the signed hash with Alices public key. Computer Security And Pgp S Mime Vs Pgp Email Security Computer Security Computer Skins Bob will then need to decrypt using his private key and verify the signature on the recovered message using Alices public key. . Because doing so required K A pub the key he believes to be Alices public key he thinks this message really mustve come from Alice and that nobody could have read it but himself. How can Bob verify that the message is from Alice o When Bob decrypts the from CS 462 at Old Dominion University. This is where digital signatures come in. 4 Bob produces a one-way hash of the document that Alice sent. When he receives the message and signature Bob decrypts the signatu...
