摘　　要：目前 ,各种信息加密、信息隐藏技术已经广泛的应用于社会经济领域 ,特别是电子商务的迅猛扩展 ,使得数据加密技术得到了更为广泛的应用和发展。简要介绍了数据加密的一般方法及基于公钥加密算法的原理与方法 ,最后详细介绍了多步加密算法的方法与步骤 ,并在此基础上 ,结合作者的实践 ,给出了一个实用的完成该加密算法的应用程序。Along with technological advancement and development of modern times civilization and economic, data encryption techniques have been degrees into community from apply of diplomatism information and military affairs. In fact, data encryption techniques are not mysteries. A general method about data encryption is introduced as well as method and process based on public-key encryption algorithm. The principle and algorithm of multi-step encryption algorithm is introduced in detail. At last, an application about the multi-step encryption algorithm is brought forward combining with the experience of the authors.
