3DES: Triple DES
3DES or Triple DES is a mode of the DES encryption algorithm that encrypts data three times with three 64-bit keys used, for an overall key length of 192 bits. Data Encryption Standard (DES) is a long-standing US encryption standard with symmetric-key encryption method standardized by ANSI in 1981 as ANSI X.3.92. DES uses a 56-bit key and uses the block cipher method, which breaks text into 64-bit blocks and then encrypts them. 3DES is a much more secure standard than the original DES. |
