3DES



3DES（即Triple DES）是DES向AES过渡的加密算法，它利用3条64位的密钥对数据举行三次加密。是DES的一个更平安的变形。它以DES为大约模块，穿越组合分组措施设计出分组加密算法。比起当时的DES，3DES更为平安。-In cryptography, Triple DES is the common name for the Triple Data Encryption Algorithm (TDEA or Triple DEA) block cipher, which applies the Data Encryption Standard (DES) cipher algorithm three times to each data block.
