NAME
zip_file_set_encryption — set encryption method for file in zip
LIBRARY
libzip (-lzip)
SYNOPSIS
#include <zip.h>
int
zip_file_set_encryption ( zip_t *archive , zip_uint64_t index , zip_uint16_t method , const char *password );
DESCRIPTION
The zip_file_set_encryption () function sets the encryption method for the file at position index in the zip archive to method using the password password . The method is the same as returned by zip_stat (3). For the method argument, currently only the following values are supported:
ZIP_EM_NONE
No encryption.
ZIP_EM_AES_128
Winzip AES-128 encryption.
ZIP_EM_AES_192
Winzip AES-192 encryption.
ZIP_EM_AES_256
Winzip AES-256 encryption.
ZIP_EM_TRAD_PKWARE
Traditional PKWare encryption. Do not use this method, it is not secure. It is only provided for backwards compatibility.
If password is NULL, the default password provided by zip_set_default_password (3) is used.
The current encryption method for a file in a zip archive can be determined using zip_stat (3).
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_file_set_encryption () fails if:
[ZIP_ER_ENCRNOTSUPP]
Unsupported compression method requested.
[ZIP_ER_INVAL]
index is not a valid file index in archive , or the argument combination is invalid.
[ZIP_ER_MEMORY]
Required memory could not be allocated.
[ZIP_ER_RDONLY]
Read-only zip file, no changes allowed.
