Cryptography is often used for short messages

Webencrypt or decrypt the plain text message using the same key, which is a secret known only to the parties involved. This is called symmetric key cryptography. It is different from public key cryptography whereby one key is used for encryption while another mathematically related key is used to decipher the message. WebCryptography can be used for more than scrambling messages. ... Methods that are used to verify that a message has not been modified while in transit. Often, this is done with digitally signed message digest codes. Nonrepudiation. Cryptographic receipts are created so that an author of a message cannot realistically deny sending a message (but ...
