radarsat1 参数说明，对卫星的各种参数进行了解释(radarsat1 parameters shows that the satellite)

在一个exe文件后面加上一个节，并设置密码，运行的时候需要输入密码才可以执行-in an exe file, insert a section, and set the password, Operation of the need to enter the password before they can implement

我写的一个基于MD5算法的一个简单的注册程序，实现很多程序上使用的注册认证机制-I wrote an MD5 algorithm based on a simple registration process to achieve a lot of programs used on the registration of authentication mechanisms

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

AES加密算法 2000年10月，NIST（美国国家标准和技术协会）宣布通过从15种侯选算法中选出的一项新的密匙加密标准。Rijndael被选中成为将来的AES。 Rijndael是在 1999 年下半年，由研究员 Joan Daemen 和 Vincent Rijmen 创建的。AES 正日益成为加密各种形式的电子数据的实际标准。 美国标准与技术研究院 (NIST) 于 2002 年 5 月 26 日制定了新的高级加密标准 (AES) 规范。-AES encryption algorithm in October 2000, NIST (National Institute of Standards and Technology Association) announced candidates from 15 kinds of algorithm selected a new encryption standard keys. Rijndael was selected to become the future of the AES. Rijndael is the second half of 1999, by researcher Joan Daemen and Vincent Rijmen created. AES encryption is increasingly becoming the various forms of de facto standard for electronic data. United States Institute of Standards and Technology (NIST) in May 26, 2002 developed a new Advanced Encryption Standard (AES) norms.
