WebSecret Key Cryptography can be used on both in-transit and at-rest data, but is commonly only used on at-rest data, as sending the secret to the recipient of the message can lead to compromise. Examples: AES DES Caesar Cipher Public Key Cryptography, or asymmetric cryptography, uses two keys to encrypt data. WebSymmetric key cryptography is an encryption system in which the sender and receiver of a message share a single, common key that is used to encrypt and decrypt the message. ...

WebPublic key cryptography is a method of encrypting or signing data with two different keys and making one of the keys, the public key, available for anyone to use.
