1.2 Features
The primary advantage of using libfko is it provides a single API for either
creating or parsing SPA data. Additional advantages include:
- It's free software
- Anybody can use, modify, and redistribute it under the terms of the GNU
General Public License (see Library Copying).
- It's lightweight
- The Perl-based implementation requires several additional Perl
modules and has a relatively large footprint in memory. This C-based
library eliminates those dependencies and has a much smaller footprint.
Using this library allows SPA to easily function on embedded
operating systems such as OpenWRT.
- It's easy
- libfko hides many of the gory details of fwknop's SPA message data
format, encoding, decoding, encrypting, decrypting, authenticating, and parsing.
In most cases, only a few function calls will be needed create or parse a
SPA message.
