Rjindeal加密算法-Rjindeal encryption algorithm

Seed加密体制代码，韩国的分组密码加密体制。(Seed encryption system code block cipher encryption system in Korea.)

软件有限次加密，对软件的使用次数进行限制-finite encryption software, software usage restrictions

利用替换算法的加密算法!-use replacement algorithm encryption algorithm!

delphi编写的加壳程序,实现对文件保护-delphi write the packers program to realize File Protection

按照分组密码运行的CBC方式，将其中的DES算法置换为S-DES，分组长度为8BIT，初始矢量V1分别设置为00H,FFH,及任意8BIT无符号整数，实现该加密/解密模型-running CBC, which will be the replacement for the DES algorithm S-DES, a length of 8BIT initial vector V1 were set to 00H, FFH, and the arbitrary 8BIT unsigned integers, the achievement of this encryption/decryption model

SHA-1Hash函数源码，可以对任何文件做Hash，得到的Hash值为160位。具有抗强碰撞，弱碰撞等能力。虽然王小云已经找到了个别碰撞。但在新的好的hash函数出来之前仍将被广泛使用。-SHA-1Hash function source, any document can be done right hash, the hash value of 160. Anti-collision, the weak capabilities of the collision. Although Bruce Schneier, had found individual collisions. But the new good hash function will be out before widespread use.

说明：  一个三d加密图像程序，有点复杂，可以参考注释理解，希望有用。(A three-d the encrypted image program, is a little more complicated, you can refer to the Notes to understand, I hope useful.)

这是最新的openssl学习的材料，是源代码，相信朋友们以前看过的都知道，这在网络方面很有用的。-This is the latest openssl learning opnenssl, is the source code, I believe that friends who have seen before, all know that this very useful in networking.

这是一个文本加密、解密系统，提供了对称加密和非对称加密两种模式。此外，还实现了数字签名及其验证功能。(This is a text encryption, decryption system provides symmetric encryption and asymmetric encryption mode. In addition, implementation of digital signature and the authentication function.)
