3DES（或称为Triple DES）是三重数据加密算法（TDEA，Triple Data Encryption Algorithm）块密码的通称。 3DES的c++实现-Cryptography Advanced Encryption Standard (Advanced Encryption Standard, AES), also known as the Advanced Encryption Standard Rijndael encryption, AES encryption

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.
