128192和256位密钥的密码Twofish的VHDL实现。

我用C#做的一个对字符串加密的程序，加密对象为26个字母大小写和0到9的数字，实现的是替代法-I used C# do a strings encryption procedures, encryption targeted at 26 case-sensitive alphanumeric 0-9 and figures to achieve the substitution

椭圆曲线公钥密码算法,可用于加密和数字签名等应用，该版本算法是有限域GF（2^n）上的算法-Elliptic curve public key cryptography algorithms can be used for encryption and digital signature applications, the version of the algorithm is a finite field GF (2 ^ n) the algorithm

带密钥的md5算法库md5lib.h共有下列函数： char* MDString (char *) /*输入任意一个字符串，经过md5算法处理后，返回结果：一个定长（32个字符） 字符串 */ char* MDFile (char *) /*输入任意一个文件名，文件内容经过md5算法处理后，返回结果：一个定长 （32个字符）字符串 */ char* hmac_md5(char* text, char* key) /*输入任意一个字符串text,和一个用做密钥的字符串key,经过hmac_md5算法处 理，返回处理结果：一个定长字符串（32个字符）*/ 具体使用方法可参考例子sample.c,其运行结果在本文后面。-Md5 algorithm with a key repository md5lib.h total of the following functions: char* MDString (char*) /* enter any one string, after md5 algorithm processing, return the result: a fixed-length (32 characters) string*/char* MDFile (char*) /* enter any of the file name, file contents through the md5 algorithm processing, return the result: a fixed-length (32 characters) string*/char* hmac_md5 (char* text, char* key) /* input a string of arbitrary text, and a string key used as key, after hmac_md5 algorithm processing, return processing results: a fixed-length string (32 characters)*/specific examples of the use of methods can be found sample.c, the results

TableCrypt is a file encryption utility. The major difference with most file encryptors is that this program uses a generated table in combination with a password to encrypt a file. This way you need 2 variables to decrypt the file. This is how it works: Generate a 10kb table file and enter a password. The password is used to pick bytes from the table file which in their turn are used to encrypt the bytes of the inputfile with XOR encryption.
