The same key is used to encrypt messages as well as decrypt messages. These algorithms are always faster but have an issue with exchanging keys. - -Symmetric Cryptography Modern cryptography began when Claude Shannon publish "Communication Theory of Secrecy Systems" in 1949. He focused on this concept by quantifying information, leading to a number of methods for encrypting and decrypting information. - -Information Theory Change to one character in plain text affect multiple characters i...

These are usually the encryption of a message digest with the senders private key. In order to verify them, the recipient uses the senders public key. They are considered good if they provide the following. Authentication Integrity Non-repudiation - ANSWER Digital Signature It is a digital document that contains a public key and some information to allow your system to verify where they key came from. This is the most common way to distribute pubic keys in asymmetric cryptography. -...
