/* * This is the header file for 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 * md5_context_s structure, pass it to MD5_Init, call MD5_Update as * needed on buffers full of bytes, and then call MD5_Final, which * will fill a supplied 16-byte array with the digest. * * Changed so as no longer to depend on Colin Plumb's `usual.h' * header definitions; now uses stuff from dpkg's config.h * - Ian Jackson <[email protected]>. * Still in the public domain. */ #ifndef MD5_H #define MD5_H #include "doomtype.h" typedef struct md5_context_s md5_context_t; typedef byte md5_digest_t[16]; struct md5_context_s { uint32_t buf[4]; uint32_t bytes[2]; uint32_t in[16]; }; void MD5_Init(md5_context_t *context); void MD5_Update(md5_context_t *context, byte const *buf, unsigned len); void MD5_UpdateInt32(md5_context_t *context, unsigned int val); void MD5_UpdateString(md5_context_t *context, char *str); void MD5_Final(unsigned char digest[16], md5_context_t *context); void MD5_Transform(uint32_t buf[4], uint32_t const in[16]); #endif /* !MD5_H */
