3DES, also known as Triple DES, is a mode of DES encryption algorithm that uses three 56 bit keys to encrypt data three times. The Data Encryption Standard (DES) is a long-standing encryption standard in the United States that uses symmetric key encryption and was standardized as ANSI X.3.92 by the ANSI organization in 1981. DES uses a 56 bit key and password block method, while in the password block method, the text is divided into 64 bit sized text blocks and then encrypted. Compared to the original DES, 3DES is more secure.
