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 * 12 * To compute the message digest of a chunk of bytes, declare an 13 * MD5Context structure, pass it to MD5Init, call MD5Update as 14 * needed on buffers full of bytes, and then call MD5Final, which 15 * will fill a supplied 16-byte array with the digest. 16 * 17 * Changed so as no longer to depend on Colin Plumb's `usual.h' 18 * header definitions; now uses stuff from dpkg's config.h 19 * - Ian Jackson <ian@chiark.greenend.org.uk>. 20 * Still in the public domain. 21 */ 22 23 #ifndef MD5_H 24 #define MD5_H 25 26 #include <qglobal.h> 27 #include <qbytearray.h> 28 #include <qstring.h> 29 30 QT_BEGIN_NAMESPACE 31 32 typedef unsigned char md5byte; 33 typedef quint32 UWORD32; 34 35 struct MD5Context { 36 UWORD32 buf[4]; 37 UWORD32 bytes[2]; 38 UWORD32 in[16]; 39 }; 40 41 static void MD5Init(struct MD5Context *context); 42 static void MD5Update(struct MD5Context *context, md5byte const *buf, unsigned len); 43 static void MD5Final(struct MD5Context *context, unsigned char digest[16]); 44 static void MD5Transform(UWORD32 buf[4], UWORD32 const in[16]); 45 46 QT_END_NAMESPACE 47 48 #endif /* !MD5_H */ 49
