aes算法java版，包含了源码和jar文件

MIME(Quoted-Printable & Base64) 编码解码程序-MIME (Quoted-Printable Base64) codec procedures

利用汇编语言实现DES加密算法-using assembly language to achieve DES encryption algorithm

为一个字节或字符数组或串计算md5值，内部只创建一个数组，节省分配时间，节省内存 完全是static方法，线程安全 注意对返回值的处理，见注释-for a byte array or character string or md5 value calculation, only to create an internal array, saving time allocated to save memory is completely static method, thread-safe attention to the return value, see note

VB的MD5算法源码 VB的MD5算法源码-VB source code of MD5 algorithm is the MD5 algorithm for VB source code of MD5 algorithm for VB source code

将其他文件隐藏在BMP图像中！好-other documents hidden in BMP image! Good

另类密码登录窗体（拼图），只有正确拼出结果图才能进入。-alternative Password Login Window (puzzles), the only correct map decorated results can be admitted.

java自行开发rsa-developed rsa

将密钥添加到文件尾部的例子- Increases the key to the document rear part example

以前发的那个只实现了SHA-1, 现在补全了, sha-160, sha-224, sha-256, sha-384, sha-512-Previously issued only to realize that the SHA-1, is now a complete, sha-160, sha-224, sha-256, sha-384, sha-512
