About OpenSSL

webatla tracks 1,213,340 live websites using OpenSSL — 0.4% of every site we index. Download the full list of websites that using OpenSSL technology as a daily JSONL export — every record includes the domain plus DNS, WHOIS, IP address, hosting country and global rank.

OpenSSL is the world's most widely used open-source cryptographic library, providing implementations of SSL/TLS protocols and a broad range of cryptographic functions including encryption, hashing, digital signatures, and certificate management. It underpins the secure communications of a vast portion of the internet's infrastructure.

Originally released in 1998 as a fork of SSLeay, OpenSSL is maintained by the OpenSSL Project and written in C. It is embedded in web servers, databases, programming language runtimes, VPNs, and countless other software systems. The 2014 Heartbleed vulnerability brought significant attention to OpenSSL's importance and led to increased funding and code auditing. OpenSSL is governed by an Apache 2.0 license since version 3.0.

Which websites are using OpenSSL?

webatla detects every site using OpenSSL and exports them as one downloadable list, so you can see who relies on this technology and what else runs alongside it.

Open the OpenSSL technology dataset to break adoption down by country and TLD, compare it with a competing technology, and track new domains over time.

Frequently asked questions

How many websites use OpenSSL?

webatla detects OpenSSL on 1.2M websites, refreshed daily — each with its domain, DNS, WHOIS, IP, country and ranking.

Can I download the list of websites using OpenSSL?

Yes, as structured JSONL. Grab a free sample first.

What's included for each site, and how fresh is it?

Domain, DNS, RDAP/WHOIS, the full technology stack, IP & country, PageRank and Harmonic — re-detected and re-exported daily.

How do I find the websites using OpenSSL?

Buy the technology dataset, then download the complete list of domains we detect using OpenSSL — re-exported every day.

What else is in the OpenSSL technology data?

Each row places OpenSSL next to the other technology on the same site, plus DNS, WHOIS, IP, country and ranking.

Can I download just the sites using OpenSSL, or the whole database?

Both. Every site running OpenSSL comes in the Technologies dataset, one downloadable file. Or buy All data for the entire database: technologies plus identity, ranking, DNS and RDAP/WHOIS for every domain, combined in one file. Daily fresh export.

How do I download the list of websites using OpenSSL?

Three steps: (1) grab the free 10,000-row sample to inspect the schema, (2) buy the Technologies dataset, (3) download the full list of every domain we detect running OpenSSL as a JSON Lines file. It is re-exported daily, so you can re-download the freshest list any time inside your access window. Each row carries the domain plus DNS, WHOIS, IP, hosting country and rank.
