3DES, also known as Triple DES, DES encryption algorithm is a model that uses three 56-bit key three times the data encryption. Data Encryption Standard (DES) is a long-standing United States encryption standard that uses symmetric key encryption method, and in 1981 organized by ANSI standard is ANSI X.3.92. 56-bit DES key and password using the block method, the method in the code block, the text is divided into 64-bit size of the text block and then encrypted. Than the original DES, 3DES is more secure.
