SHA-256源代码，三个对外的函数：void SHA256Init (SHA256Context *sc) void SHA256Update (SHA256Context *sc, const void *data, uint32_t len) void SHA256Final (SHA256Context *sc, uint8_t hash[SHA256_HASH_SIZE]) 第一个函数初始化，第二个函数输入要hash的字符串，第三个函数输出结果(SHA-256 source code, three external function: void SHA256Init (SHA256Context* sc) void SHA256Update (SHA256Context* sc, const void* data, uint32_t len) void SHA256Final (SHA256Context* sc, uint8_t hash [SHA256_HASH_SIZE]) The first function is initialized, the second hash function, enter the string, the third function of output)

信息加密原码，用md5算法实现，开发语言：c(original message encryption code used md5 algorithm, the development of language : c)

此资料为加密芯片资料，里面有例程，是很好的资料(This data encryption chip data, there are routine, the data is good)
