So choose wisely. 00062 00063 */ 00064 00065 #ifndef __BARRY_SHA1_H__ 00066 #define __BARRY_SHA1_H__ 00067 00068 #include "dll.h" 00069 00070 #define SHA_DIGEST_LENGTH 20 00071 00072 namespace Barry { 00073 00074 struct BXEXPORT SHA_CTX { 00075 unsigned int H[5]; 00076 unsigned int W[80]; 00077 int lenW; 00078 unsigned int sizeHi,sizeLo; 00079 }; 00080 00081 BXEXPORT void SHA1(const void *dataIn, int len, unsigned char *hashout); 00082 BXEXPORT void SHA1_Init(SHA_CTX *ctx); 00083 BXEXPORT void SHA1_Update(SHA_CTX *ctx, const void *dataIn, int len); 00084 BXEXPORT void SHA1_Final(unsigned char hashout[20], SHA_CTX *ctx); 00085 00086 } 00087 00088 #endif 00089
