zip_set_default_password — set default password for encrypted files in zip


libzip (-lzip)


#include <zip.h>


zip_set_default_password(zip_t *archive, const char *password);


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 password 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.


zip_set_default_password() fails if:


Required memory could not be allocated.
