Triple DES

Triple DES (3DES or TDEA) is a symmetric-key block cipher that applies the DES cipher algorithm three times to each data block. Triple DES increases the effective security of the 56-bit DES to 112 bits.

Attacks

Weak keys

As with DES, the Triple DES block cipher has several weak keys that should be checked for, such as:

  • 0000000000000000FFFFFFFFFFFFFFFF
  • FB13347FE570DC4FFB13347FE570DC4F
