le_dns_online

What is it ?

le_dns_online is a frontend intended to provide dns validation of Let's Encrypt for the french cloud provider & hoster online.net. More specifically, its goal is to integrate easily with acme.sh.

Building instructions

You need to use the Rust nightly compiler for now as I use the try_trait feature.

cargo build --release

And the binary is located in 'target/release/le_dns_online'.

How do I install it ?

First, build the binary according to the 'building instructions' section. You just need to add 'dns_online.sh' and the binary le_dns_online to the dnsapi folder inside '~/.acme.sh' (or whichever folder you use for acme.sh). You must then update the api_key in dns_online.sh to your private key (given at https://console.online.net/en/api/access) and you're good to go !

How does it work ?

Acme.sh calls the fonction 'dns_online_add' from 'dns_online.sh', which calls le_dns_online binary.

le_dns_online then:

1. Add the record needed for Let's Encrypt in the current zone

2. Return its id to delete the record later on

Acme.sh takes back control again, and execute the authentification request. Subsequently, it calls 'dns_online_rm', which calls (again) le_dns_online binary.

This time, le_dns_online simply :

1. delete the temporary record with its id

And voilà ! You have your certs validated ;)

Remaining work

Logging !

Known issues

Do NOT use this program concurrently !!! This may break the ongoing validation (or slightly worse than corrupting a free and simple process, corrupt your DNS zone, event if it's also less likely).

Can I contribute ?

Sure, go ahead ! Prepare youself to dig your way through some terrible Rust code, however ^_^
