    to searchsecurity.techtarget.com‚ “Encryption is the conversion of data into a form‚ called a ciphertext that cannot be easily understood by unauthorized people.” In order to understand the data or the message that is being sent‚ the receiver must be able to decrypt the message. Decryption thus refers to the process of converting the message from cipher text into its original format or plaintext whereby the reader would be able to understand the message. Encryption is used to ensure the confidentiality

    network. Date encryption is‚ in its simplest terms‚ the translation of data into a secret code. In order to read an encrypted file‚ the receiver of the file must obtain a secret key that will enable him to decrypt the file. A deeper look into cryptography‚ cryptanalysis‚ and the Data Encryption Standard (DES) will provide a better understanding of data encryption. Cryptographic Methods There are two standard methods of cryptography‚ asymmetric encryption and symmetric encryption. Data that is

    two basic types of encryption; asymmetrical and symmetrical. Asymmetrical uses two keys; a public and a private key. The public and the private keys have unique characteristics. In asymmetric encryption you can encrypt with a public key that has a matching private key used for decryption. The other basic type of encryption is called symmetric encryption; the main difference between the two is that symmetrical encryption uses only one key; a private key used for both encryption and decryption.
