This code was 7 * written by Colin Plumb in 1993, no copyright is claimed. 8 * This code is in the public domain; do with it what you wish. 9 * 10 * Equivalent code is available from RSA Data Security, Inc. 11 * This code has been tested against that, and is equivalent, 12 * except that you don't need to include two pages of legalese 13 * with every copy. 14 * 15 * To compute the message digest of a chunk of bytes, declare an 16 * MD5Context structure, pass it to MD5Init, call MD5Update as 17 * needed on buffers full of bytes, and then call MD5Final, which 18 * will fill a supplied 16-byte array with the digest. 19 * 20 * Changed so as no longer to depend on Colin Plumb's `usual.h' 21 * header definitions; now uses stuff from dpkg's config.h 22 * - Ian Jackson <ijackson (at) nyx.cs.du.edu>. 23 * Still in the public domain. 24 * 25 * Josh Coalson: made some changes to integrate with libFLAC. 26 * Still in the public domain, with no warranty. 27 */ 28 29 #include "FLAC/ordinals.h" 30 31 typedef union { 32 FLAC__byte *p8; 33 FLAC__int16 *p16; 34 FLAC__int32 *p32; 35 } FLAC__multibyte; 36 37 typedef struct { 38 FLAC__uint32 in[16]; 39 FLAC__uint32 buf[4]; 40 FLAC__uint32 bytes[2]; 41 FLAC__multibyte internal_buf; 42 size_t capacity; 43 } FLAC__MD5Context; 44 45 void FLAC__MD5Init(FLAC__MD5Context *context); 46 void FLAC__MD5Final(FLAC__byte digest[16], FLAC__MD5Context *context); 47 48 FLAC__bool FLAC__MD5Accumulate(FLAC__MD5Context *ctx, const FLAC__int32 * const signal[], unsigned channels, unsigned samples, unsigned bytes_per_sample); 49 50 #endif 51
