wg_to_hostname_if

wg_to_hostname_if translates WireGuard configuration files to OpenBSD's hostname.if(5) format. Specifically, it deals with client configuration files. It also performs some validation to ensure that each option in each section is set to a reasonable value.

Example usage

There is a file named test.ini in the tests directory. Here are its contents.

$ cat tests/test.ini
[Interface]
PrivateKey = yPlLc8Frd05JcfMBzs/p+53b5tfX29WhQbwuyJkdnEs=
Address = 192.168.1.23/32,fd12:3456:789a:1::1/128

[Peer]
PublicKey = YV1sIDB+wgwYqlgxAGnvo2h80v+r7Y5BgHKLoYwt2Xg=
AllowedIPs = 0.0.0.0/0,::0/0
Endpoint = 73.60.105.217:11507

These are the contents of that file translated to hostname.if format.

$ ./wg_to_hostname_if.py tests/test.ini
wgkey yPlLc8Frd05JcfMBzs/p+53b5tfX29WhQbwuyJkdnEs=
wgpeer YV1sIDB+wgwYqlgxAGnvo2h80v+r7Y5BgHKLoYwt2Xg= \
