1、编写程序构造一RSA密钥； 2、编写程序实现快速指数算法； 3、编写程序生成大素数； 4、实现RSA密码体制 -1, the preparation of procedures for constructing a RSA key 2, the preparation of procedures for fast index algorithm 3, the preparation process to generate large prime numbers 4, t

此加密算法采用维吉尼亚加密体制进行第一重加密，自动密钥体制进行第二重加密，故一般破译比较有难度-This encryption algorithm the Virginia encryption system first re-encryption, automatic key system for the second layer of encryption, it is generally decipher more difficult

DES( Data Encryption Standard)算法，于1977年得到美国政府的正式许可，是一种用56位密钥来加密64位数据的方法。虽然56位密钥的DES算法已经风光不在,而且常有用Des加密的明文被破译的报道,但是了解一下昔日美国的标准加密算法总是有益的,而且目前DES算法得到了广泛的应用,在某些场合,她仍然发挥着余热^_^.-DES (Data Encryption Standard) algorithm, in 1977 the United States government
