Step 2: The encrypted message reaches Bob.Step 1: Alice first uses Bob’s public key to encrypt the message.
The process for the above image is as follows: Using separate keys for encryption and decryption, as seen in the figure above, has helped eliminate key exchange, as seen in the case of symmetric encryption.įor example, if Alice needs to send a message to Bob, both the private and public keys must belong to Bob. However, you must generate both keys from the receiver’s end. You use the public key for encryption meanwhile, you use the private key for decryption. You utilize two distinct keys in asymmetric encryption methods, one for encryption and the other for decryption. To maintain the authenticity and integrity of such documents holding critical information, the DSA Algorithm was proposed and passed as a global standard for verifying digital signatures.īefore moving forward with the algorithm, you will get a refresher on asymmetric encryption, since it verifies digital signatures according to asymmetric cryptography architecture, also known as public-key cryptography architecture. Without a doubt, most of the users reading this have had to digitally sign some official documents over the past couple of years because of the lack of face-to-face interaction and standard distance constraints.
