I can't really make heads or tails from your description. How is the current file determined? On what criteria are the files selected? Time? A pattern in the file name? What kind of system are you on (and don't say UNIX now, we need the specific version and/or distribution)?

zip_set_default_password
ZIP_SET_DEFAULT_PASSWORD(3) Library Functions Manual ZIP_SET_DEFAULT_PASSWORD(3)
NAME
zip_set_default_password - set default password for encrypted files in zip
LIBRARY
libzip (-lzip)
SYNOPSIS
#include <zip.h>
int zip_set_default_password(struct zip *archive, const char *password);
DESCRIPTION
The zip_set_default_password function sets the default password used when accessing encrypted files. If password is NULL, the default
password is unset.
If you prefer a different password for single files, use zip_fopen_encrypted(3) instead of zip_fopen(3). Usually, however, the same pass-
word is used for every file in an zip archive.
RETURN VALUES
Upon successful completion 0 is returned. Otherwise, -1 is returned and the error information in archive is set to indicate the error.
ERRORS
zip_set_default_password fails if:
[ZIP_ER_MEMORY]
Required memory could not be allocated.
