/* * This code implements the MD5 message-digest algorithm. * The algorithm is due to Ron Rivest. This code was * written by Colin Plumb in 1993, no copyright is claimed. * This code is in the public domain; do with it what you wish. * * Equivalent code is available from RSA Data Security, Inc. * This code has been tested against that, and is equivalent, * except that you don't need to include two pages of legalese * with every copy. * * To compute the message digest of a chunk of bytes, declare an * MD5Context structure, pass it to MD5Init, call MD5Update as * needed on buffers full of bytes, and then call MD5Final, which * will fill a supplied 16-byte array with the digest. */ #ifndef _MD5_H_ #define _MD5_H_ #include #include #define MD5_HASHBYTES 16 typedef struct MD5Context { uint32_t buf[4]; uint32_t bits[2]; unsigned char in[64]; } MD5_CTX; extern void media_thumb_MD5Init(MD5_CTX *context); extern void media_thumb_MD5Update(MD5_CTX *context, unsigned char const *buf, unsigned len); extern void media_thumb_MD5Final(unsigned char digest[MD5_HASHBYTES], MD5_CTX *context); extern void MD5Transform(uint32_t buf[4], uint32_t const in[16]); #endif
