c语言实现dES加密算法 c语言实现加密解密 在密码学中,微型加密算法(Tiny Encryption Algorithm,TEA)是一种易于描述和执行的块密码,通常只需要很少的代码就可实现。其设计者是剑桥大学计算机实验室的大卫·惠勒与罗杰·尼达姆。这项技术最初于1994年提交给鲁汶的快速软件加密的研讨会上,并在该研讨会上演讲中首次发表。
RSA algorithm is a process of encrypting plain text in blocks, every block has a binary value lesser than some n number. The size of block should be less than log (n) or equal to log (n), public-key cryptosystem was implemented by RSA algorithm In this Journal we are going to...

1.2 扩展欧几里得算法 扩展欧几里得算法(英语:Extended Euclidean algorithm)是欧几里得算法(又叫辗转相除法)的扩展。已知整数a、b,扩展欧几里得算法可以在求得a、b的最大公约数的同时,能找到整数x、y(其中一个很可能是负数),使它们满足贝祖等式 ax+by=gcd(a,b).ax+by=gcd(a,b). 如果aa是负数,可以把问题转化...
