秘钥生成过程 1.选择两个不相等的质数p和q 2.计算q与p的乘积n 3.计算n的欧拉函数φ(n) 4.选择一个整数e，条件是1< e < φ(n)，且e与φ(n) 互质 5.计算e对于φ(n)的模反元素d（如果两个正整数a和n互质，那么一定可以找到整数b，使得 ab-1 被n整除，或者说ab被n除的余数是1。这时，b就叫做a的“模反元素”。） 用公式表 … See more 其中m为模数，r为余数 讨论推导过程，如下： 1.余数计算： 总可以找到一个a∈Z，使得 由于a - r = q · m（m除a-r），上面的表达式可 … See more 可以通过一种简单方法判断给定元素a的逆元是否存在： 当且仅当gcd(a,m) = 1,一个元素a∈Z存在乘法逆元a⁻¹，其中gcd表示最大公约数。 举例： Z₂₆中15的乘法逆元是否存在？ Z₂₆中14的乘法逆元是否存在？ See more easyrsa1 利用factordb在线分解n，得到 写脚本 easyrsa2 题目中e相同，n，c不同，求出n1与n2的最大公因数即为p，之后就可以得到q和d，从而 … See more WebThe original Baudot code was invented by Émelie Baudot in 1870.
