WebbThe Triple Data Encryption Standard (DES), often written 3DES, is a version of the original DES encryption algorithm that encrypts data three times. The Triple DES uses three 64-bit keys, so the key length is 192 bits. Triple DES is a symmetric encryption, and the key is … WebbSecurity: Encryption helps prevent data breaches, whether the data is in transit or at rest. If a corporate device is lost or stolen and its hard drive is properly encrypted, the data on that device will still be secure. Similarly, encrypted communications enable the communicating parties to exchange sensitive data without leaking the data.
