Zip and password protect non-interactively
I'm wondering if there is a way to zip a file and password protect it non-interactively.
zip -e will prompt for a password but I don't want a prompt. This needs to be done automatically as part of a shell script.
I'm using the zip command because the will be unzipped by a Windows machine.
I'm sure there are utilities I could buy which would accomplish this but I was hoping that there is an easier way to do it.
Thanks,
Sav

zip_fopen_index_encrypted
ZIP_FOPEN_ENCRYPTED(3) Library Functions Manual ZIP_FOPEN_ENCRYPTED(3)
NAME
zip_fopen_encrypted , - .Nm zip_fopen_index_encrypted open encrypted file in zip archive for reading
LIBRARY
libzip (-lzip)
SYNOPSIS
#include <zip.h>
struct zip_file * zip_fopen_encrypted(struct zip *archive, const char *fname, int flags, const char *password);
struct zip_file * zip_fopen_index_encrypted(struct zip *archive, zip_uint64_t index, int flags, const char *password);
DESCRIPTION
The zip_fopen_encrypted function opens the encrypted file name fname in archive using the password given in the password argument. 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) ).
RETURN VALUES
Upon successful completion, a
struct zip_file pointer is returned. Otherwise, NULL is returned and the error code in archive is set to indicate the error.
ERRORS
[ZIP_ER_NOPASSWD] No password was provided.
The function zip_fopen_encrypted may also fail and set for any of the errors specified for the routine zip_fopen(3).
The function zip_fopen_index_encrypted may also fail and set for any of the errors specified for the routine zip_fopen_index(3).
