Triple DES or 3DES is a mode of the DES encryption algorithm that encrypts data three times. Three 64-bit keys are used, instead of one, for an overall key length of 192 bits. 

Advanced Encryption Standard (AES) is a symmetric 128-bit block data encryption technique and a key size of 128, 192, or 256-bits.
