RSA算法 :首先, 找出三个数, p, q, r, 其中 p, q 是两个相异的质数, r 是与 (p-1)(q-1) 互质的数...... p, q, r 这三个数便是 person_key，接著, 找出 m, 使得 r^m == 1 mod (p-1)(q-1)..... 这个 m 一定存在, 因为 r 与 (p-1)(q-1) 互质, 用辗转相除法就可以得到了..... 再来, 计算 n = pq....... m, n 这两个数便是 public_key ，编码过程是, 若资料为 a, 将其看成是一个大整数, 假设 a < n.... 如果 a >= n 的话, 就将 a 表成 s 进位 (s

一个周期3的多表代替密码，第1个表由密钥字法产生（密钥字自拟），第2个表由洗牌法产生（注意，字母a~z与数字0~25一一对应），第三个表由公式法产生（数学公式自拟，注意它须是Z26上的一个一一变换）-a cycle of three multi-table instead of passwords, a table by key word method, (key word from the intended), Table No. 2 produced by shuffling method (note, a letter with a number of z ~ 0 ~ 25 he gathers), 3rd tables generated by the formula (from the proposed mathematical formula, it should pay attention to the Z26 is a transformation on January 1)

AES加密算法 2000年10月，NIST（美国国家标准和技术协会）宣布通过从15种侯选算法中选出的一项新的密匙加密标准。Rijndael被选中成为将来的AES。 Rijndael是在 1999 年下半年，由研究员 Joan Daemen 和 Vincent Rijmen 创建的。AES 正日益成为加密各种形式的电子数据的实际标准。 美国标准与技术研究院 (NIST) 于 2002 年 5 月 26 日制定了新的高级加密标准 (AES) 规范。-AES encryption algorithm in October 2000, NIST (National Institute of Standards and Technology Association) announced candidates from 15 kinds of algorithm selected a new encryption standard keys. Rijndael was selected to become the future of the AES. Rijndael is the second half of 1999, by researcher Joan Daemen and Vincent Rijmen created. AES encryption is increasingly becoming the various forms of de facto standard for electronic data. United States Institute of Standards and Technology (NIST) in May 26, 2002 developed a new Advanced Encryption Standard (AES) norms.
