The -t option is required, and is used to specify the type of encryption key we're interested in generating.
t选项必不可少，它用于指定想要生成的加密密钥的类型。
It is proved that this public key cryptosystem based on compound encryption has not been influenced on time complexity and space complexity, but it has more security t.
实践表明，这种基于复合加密的公钥密码系统，算法的时间复杂度和空间复杂度并未受到影响，但其安全性较早期各同类系统更高、更易被用户采纳。
Modul ar exponentiation algorithm scans encryption from right to sot, so t wo modular multiplications can be processed parallelly.
模幂算法采用从右到左扫描指数的方法，可以使得两次模乘运算同时进行。
