Can someone help me port my code from
void * uzFile = unzOpen("zip filename");
to use the unzOpenCurrentFilePassword from minizip ? I want to protect my zip file with a password.
I tried many times but I failed using it. Thanks
extern int ZEXPORT unzOpenCurrentFilePassword OF((unzFile file,
const char* password));
/*
Open for reading data the current file in the zipfile.
password is a crypting password
If there is no error, the return value is UNZ_OK.
*/

Before you compile zlib, remove the definition of NOUNCRYPT in unzip.c. Then "unzOpenCurrentFilePassword will be enabled".
unzip.c Line 72:
#ifndef NOUNCRYPT
//#define NOUNCRYPT Comment this line, so unzip protected files will be enabled
#endif
Why? Among other things, the definition of NOUNCRYPT causes an absurd return in unzOpenCurrentFilePassword function.
extern int ZEXPORT unzOpenCurrentFile3 (unzFile file, int* method,
int* level, int raw, const char* password)
[...]
# ifndef NOUNCRYPT
char source[12];
# else
if (password != NULL)
return UNZ_PARAMERROR;
# endif
