What's
lencr.org
lencr
org
is a domain name owned by Lets Encrypt: We use it to host data that is referenced inside the certificates we
issue_
Why is my computer fetching this data? Is it malicious?
No, the data on
lencr.org
is never malicious. When a device connects to Lencr.org
it's because client software on that
device (like a web browser or an app) connected to another site,
saw a Let's
Encrypt certificate, and is trying to verify that its
valid. This is routine for many clients:
We can't speak to whether the other site being connected to is malicious. If youre
investigating network activity that seems
unusual, thenyou
want to focus on the connection that started just before the connection to
lencr.org
The pattern of clients' connections to
Lencr.org  might look unusual or intermittent: Clients might never retrieve this data;
only retrieve subsets of it; or
'cache" some data for efficiency, so theyll only access it sometimes (the first time they need it;
and when the data may have expired)
What exactly is this data for?
