#ifndef FLAC__PRIVATE__MD5_H #define FLAC__PRIVATE__MD5_H /* * 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 * 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. * * 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 <ijackson@nyx.cs.du.edu>. * Still in the public domain. * * Josh Coalson: made some changes to integrate with libFLAC. * Still in the public domain, with no warranty. */ #include "FLAC/ordinals.h" typedef union { FLAC__byte *p8; FLAC__int16 *p16; FLAC__int32 *p32; } FLAC__multibyte; typedef struct { FLAC__uint32 in[16]; FLAC__uint32 buf[4]; FLAC__uint32 bytes[2]; FLAC__multibyte internal_buf; size_t capacity; } FLAC__MD5Context; void FLAC__MD5Init(FLAC__MD5Context *context); void FLAC__MD5Final(FLAC__byte digest[16], FLAC__MD5Context *context); FLAC__bool FLAC__MD5Accumulate(FLAC__MD5Context *ctx, const FLAC__int32 * const signal[], uint32_t channels, uint32_t samples, uint32_t bytes_per_sample); #endif
