1/* 2 * This is the header file for the MD5 message-digest algorithm. 3 * The algorithm is due to Ron Rivest. This code was 4 * written by Colin Plumb in 1993, no copyright is claimed. 5 * This code is in the public domain; do with it what you wish. 6 * 7 * Equivalent code is available from RSA Data Security, Inc. 8 * This code has been tested against that, and is equivalent, 9 * except that you don't need to include two pages of legalese 10 * with every copy. 11 * To compute the message digest of a chunk of bytes, declare an 12 * MD5Context structure, pass it to MD5Init, call MD5Update as 13 * needed on buffers full of bytes, and then call MD5Final, which 14 * will fill a supplied 16-byte array with the digest. 15 * 16 */ 17 18#ifndef TALK_BASE_MD5_H__ 19#define TALK_BASE_MD5_H__ 20 21#ifdef __cplusplus 22extern "C" { 23#endif 24 25typedef long unsigned int uint32; 26typedef struct MD5Context MD5_CTX; 27 28#define md5byte unsigned char 29 30struct MD5Context { 31 uint32 buf[4]; 32 uint32 bits[2]; 33 uint32 in[16]; 34}; 35 36void MD5Init(struct MD5Context *context); 37void MD5Update(struct MD5Context *context, md5byte const *buf, unsigned len); 38void MD5Final(unsigned char digest[16], struct MD5Context *context); 39void MD5Transform(uint32 buf[4], uint32 const in[16]); 40 41#ifdef __cplusplus 42}; 43#endif 44 45#endif // TALK_BASE_MD5_H__ 46
