RSA 加密算法
RSA算法
1978年就出现了这种算法,它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。算法的名字以发明者的名字命名:Ron Rivest, AdiShamir 和Leonard Adleman。但RSA的安全性一直未能得到理论上的证明。
RSA的安全性依赖于大数难于分解这一特点。公钥和私钥都是两个大素数(大于100个十进制位)的函数。据猜测,从一个密钥和密文推断出明文的难度等同于分解两个大素数的积。
密钥对的产生。选择两个大素数,p 和q 。计算:n

分形几何--用简单构造复杂的艺术。
对图形的放大有两种,一种是光栅放大,放大后图形的边界会产生锯齿;另一种是矢量放大,采用的是关系计算的方法,放大的图形不会出现锯齿和模糊。基于Julia的方法属于矢量放大,该方法被称为“分形显微镜”。是一个很有用的功能模块。-Fractal geometry- with a simple structure is complicated art. Amplification of the graphics there are two types of grating amplification, the amplified graphics have jagged borders the other is to enlarge the vector used is a method of calculation, to enlarge the graphics will not appear jagged and fuzzy.
