RSA算法

建立一个RSA密码体制的过程如下：　　1.用户选择一对不同的大素数p，q，将其保密。　　2.令n=p*q,用户公布n（素数乘以素数还是素数）.欧拉函数Ψ(n) = (p-1)*(q-1),保密。　　3.选区正整数d,使其满足gcd(d,Ψ(n)) = 1,将d保密。　　4.根据ed≡1modΨ(n),计算e并将其公布。　　则公开钥k1 = (n,e) 　　私钥k2 = (p...

Silverlight中非对称加密及数字签名RSA算法的实现

RSA算法是第一个既能用于数据加密也能用于数字签名的算法。它易于理解和操作，也很流行。它的安全性是基于大整数素因子分解的困难性，而大整数因子分解问题是数学上的著名难题，至今没有有效的方法予以解决，因此可以确保RSA算法的安全性。到目前Silverlight4 Beta发布为止，Silverlight中仍然没有提供非对称加密及数字签名相关的算法。而.NET F...
