Does anyone have pros and cons together for comparing these encryption algorithms ? Use AES. In more details: DES is the old "data encryption standard" from the seventies. Its key size is too short for proper security (56 effective bits; this can be brute-forced, as has been demonstrated more than ten years ago ). Also, DES uses 64-bit blocks, which raises some potential issues when encrypting several gigabytes of data with the same key (a gigabyte is not that big nowadays). 3DES is a trick to reuse DES implementations, by cascading three instances of DES (with distinct keys). 3DES is believed
