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.

    …/decryption. Some, such as 3DES, were originally designed to be implemented in hardware and can perform slowly when implemented in software on your computer or phone's browser. Others, such as AES, are so popular that CPU makers like Intel have added dedicated instructions to their chips to make them run faster. A decade ago, TLS data encryption added…
