数据加密算法（Data Encryption Algorithm，DEA）的数据加密标准（Data Encryption Standard，DES）是规范的描述，它出自 IBM 的研究工作，并在 1997 年被美国政府正式采纳。它很可能是使用最广泛的秘钥系统，特别是在保护金融数据的安全中，最初开发的 DES 是嵌入硬 件中的。通常，自动取款机（Automated Teller Machine，ATM）都使用 DES。
此源码可完成简单的DES加密解密-Data encryption algorithm (Data Encryption Algorithm, DEA) of the Data Encryption Standard (Data Encryption Standard, DES) is to standardize the descr iption, it comes from IBM' s research work, and in 1997 formally adopted by the U.S. government. It is probably the most widely used secret key system, especially in protecting the security of financial data, the initial development of the DES is embedded in hardware. Typically, ATM (Automated Teller Machine, ATM) are the use of DES. This source to be completed by a simple DES encryption and decryption
