sha1.h

只包括两个核心文件sha1.cpp及sha1.h 计算数据的sha1摘要。简单

#ifndef SHA1_H
#define SHA1_H

#define SHA1_MAC_LEN 20

typedef unsigned int	u32;

typedef struct {
        u32 state[5];
        u32 count[2];
        unsigned char buffer[64];
} SHA1_CTX;

void SHA1Init(SHA1_CTX *context);
void SHA1Update(SHA1_CTX *context, unsigned char const *data, u32 len);
void SHA1Final(unsigned char digest[20], SHA1_CTX* context);
void SHA1Transform(u32 state[5], const unsigned char buffer[64]);

#endif /* SHA1_H */
