The cryptography
the world depends on.
Open, audited, and maintained by the team that wrote it, because privacy is a fundamental human right.
A company built by the people who write the crypto.
Three pillars define the OpenSSL Corporation, the company, the people, and the community we convene every year.
What is the OpenSSL Corporation
OpenSSL Corporation provides direct access to the experts behind the world's most widely-deployed cryptographic library, plus engineering, FIPS certification, and support around it.
About usMeet the team
Board, management, engineers, and contributors operating across three continents, the people who write, review, and ship the cryptographic primitives the internet runs on.
LeadershipOpenSSLConference
The annual gathering of the OpenSSL community, maintainers, contributors, integrators, regulators, and the enterprises that depend on us. Prague · 13–15 October 2026.
openssl-conference.orgWe have shipped the cryptography of the open internet for twenty-eight years.
The Corporation funds the next twenty-eight.
From the team behind the library.
Updates, insights, and field reports from the maintainers of the world's most widely-used cryptographic library.
The OpenSSL Library 3.0 series reached end of life on 7 September 2026.
On 7 September 2026 the OpenSSL Library 3.0 series reached end of life: no further fixes, security fixes included. Where 3.0 sits underneath the software you chose, who is still backporting, and the two supported ways off it, the 3.5 LTS line or Extended LTS.
