Switching from letsencrypt (client) to acme-client - where is my account key? I started using letsencrypt when there was an "official" client called `letsencrypt`. I now want to change to `acme-client` \- that is, the C implementation. I think I manage to configure my sites, and find the certificates for them, but I get the error acme-client: bad HTTP: 403 acme-client: transfer buffer: [{ "type": "urn:acme:error:unauthorized", "detail": "No registration exists matching provided key", "status": 403 }] (120 bytes) I don't think I got the account key right. Where did `letsencrypt` store that? I find a directory called `/etc/letsencrypt/accounts`, but below, there are no `pem`-files, only `json`with strange content... So my questions are: * Did `letsencrypt` store the account key in `pem`-format? * If so, where can I find it? * If not - is the key stored anywhere in a way that is transformable to `pem`-format?

Another solution, much easier, is to re-register the account using


acme-client -DAvv


after having opened port 80 and configured `httpd` to answer calls with the additional


location "/.well-known/acme-challenge/*" {
root "/acme"
root strip 2
}
