OpenSSL的RSA算法应用举例。是用VC写的，有实用价值。(RSA algorithm of OpenSSL is used and given an example. Written with VC, there is practical value. )

SPN代换-置换算法的c实现，以及使用差分分析进行破解。(SPN substitution- replacement algorithm c implementation, and use of differential analysis to crack.)

个人觉得很不错的简单代码，用很少的程序实现，非常值得一看-in my view, it s a nice and simple code with a few program to achieve the aim. worth to take a look

While there are many AES cores around, this one is designed with LUT6 based FPGA architecture in mind from day one.  The AES Decryption Core for FPGA implements the decryption portion of the AES (a.k.a. Rijndael) algorithm described in the FIPS-197 specification. Key lengths of 128 / 192 / 256 bits are supported, each with a separate instantiation wrapper. Since the core is designed to take advantage of LUT6 based FPGA archit

简单演示了下如何利用DELPHI制作加壳器-Simple demonstration of how to use the next production加壳browser DELPHI

sha256计算代码，非常好用的代码，大家可以用这个代码直接计算哈希值，sha256实现 依次执行 SHA256Init、 SHA256Update SHA256Final 三个函数即可得到sha256结果(sha256 sourse code，Is very usefull)

ecc加密算法，通过c语言实现。希望有帮助(ecc c++)

说明：  编制程序，将输入的一行字符以加密的形式输出，然后将其解密，解密的字符串序列与输入的正文相比较，吻合时输出解密的正文，否则解密失败。 加密时，将每个字符的ascii码依次反复加上“4962873”中的数字，并在32（‘’）~122（‘z’）之间作模运算。解密与加密的顺序相反。例如输入正文“the result of 3 and 2 is not 8” 结果为： (Programming, the input line character output in an encrypted form, and then decrypted, the decrypted text sequence of characters compared with the input, output to decrypt the body of the agreement, otherwise the decryption failed. Encryption, ascii code of each character in turn repeatedly with &quot 4962873&quot in the figures, and 32 (' ' )~ 122 (' z' ) as a model between the operations. Decryption and encryption in reverse order. For example, enter the text &quot the result of 3 and 2 is not 8&quot results:)
