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.

    …-grade CPUs made in the last 5 years, such as Intel's Xeon line, support AES-NI. However, older virtualized servers and cloud servers often don't support these instructions. Amazon's M1 class of EC2 instances does not support AES-NI, whereas Amazon's current class of M3 instances do. If you are using a hosted service, check with your hosting provider…
