本系统实现了一个基本的混合密码系统。它使用DES作为对称密钥算法，RSA作为公开密钥算法。本系统特点如下：1：提供了俩个加密接口。混合加密，DES加密。2：本系统的DES可以进行1次DES加密(标准DES加密)和3次DES加密。它会根据密钥长度，自动选择加密方案。当密钥长度在64位以内时它将使用标准DES加密，当密钥长度超过64位后，系统将设置第2密钥，并启用3次DES加密。其密钥长度可达112位，并且它还具有很强的扩展性，提供了3种加解密接口：文件接口，文件句柄接口(可以供其他加密系统使用，本系统的混合加密模块就是使用这个接口)，和内存缓冲区接口。另外它还能检验密钥的正确性，因为加密时，它将加密后的密钥密文也存入文件中，解密时，先用当前密钥解密密钥密文，如果所得的密钥明文与当前密钥相同，则当前密钥应该是正确的。3：本系统的RSA密钥长度最大可达600位16进制数(约合720位10进制数)。加/解密时你可以从文件中导入密钥。4：本系统可产生长度最大可达300位16进制(约合360位10进制数)的大素数，你可以导出素数，也可以从文件中导入素数，也可以产生一个指定长度的随机大素数...
