In cryptography, Triple DES is the common name for the Triple Data Encryption Algorithm (TDEA or Triple DEA) symmetric-key block cipher, which applies the Data Encryption Standard (DES) cipher algorithm three times to each data block. The original DES cipher's key size of 56 bits was generally sufficient when that algorithm was designed, but the availability of increasing computational power made brute-force attacks feasible. Triple DES provides a relatively simple method of increasing the key size of DES to protect against such attacks, without the need to design a completely new block cipher algorithm.

    … significant overhead. Today, Moore's law and dedicated support for certain ciphers in CPUs has essentially eliminated this overhead, provided you select the right cipher. The consensus from both security engineers and administrators that run large TLS websites is to use AES, with 128 bit keys. We can see from the chart below that AES running on a CPU…
