The purpose of the extra step is to allow an email to be sent securely to multiple recipients. Encryption dates back approximately 4000 years. A symmetric key, or secret key, uses one key to both encode and decode the information. Data encryption is a computing process that encodes plaintext/cleartext (unencrypted, human-readable data) into ciphertext (encrypted data) that is accessible only by authorized users with the right cryptographic key. A key is a long sequence of bytes generated by a complex algorithm. Most digital security measures,everything from safe browsing to secure email, depend on it. The code mentioned above would be a very simple form of . If the last chunk to be processed is smaller than 128 bits, it is padded to 128 bits. Elevators B. Today, there are various algorithms in use that are based on encryption that is either symmetric or asymmetric, but before we dive into the details, lets see what encryption algorithms are. Encryption is designed to protect your data, but encryption canalso be used against you. Hashing techniques may also add unique, random data called asalt to the passwords before they are hashed. The recipients email program uses their private key to decrypt the random key which is then used to decrypt the message. There are two kinds of cryptographic key systems, symmetric, and asymmetric. Because ofadvances in technology and decreases in the cost of hardware, DES isessentially obsolete for protecting sensitive data. Encryption is a way of scrambling data so that only authorized parties can understand the information.
