zip_fopen_encrypted
() function opens the encrypted
file name fname in archive using
the password given in the password argument. If
password is NULL
or the empty
string, the default password is used (see
zip_set_default_password(3)).
The flags argument are the same as for
zip_fopen(3).
The zip_fopen_index_encrypted
() function
opens the file at position index, see
zip_fopen_index(3). These
functions are called automatically by
zip_fopen(3); you only need to call
them if you want to specify a non-default password (see
zip_set_default_password(3)).
NULL
is returned and the error
code in archive is set to indicate the error.
ZIP_ER_NOPASSWD
]The function zip_fopen_encrypted
() may
also fail and set zip_err for any of the errors
specified for the routine
zip_fopen(3).
The function zip_fopen_index_encrypted
()
may also fail and set zip_err for any of the errors
specified for the routine
zip_fopen_index(3).
zip_fopen_encrypted
() and
zip_fopen_index_encrypted
() were added in libzip 1.0.
ZIP_ER_WRONGPASSWD
, but if the mismatch is not
detected, a zlib error may be returned later instead. Since zlib errors can
also be caused by broken compressed data, there is no way to make sure if the
password was incorrect or if it was correct, but the compressed data was
invalid.
