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.
