OpenSSL end-of-life: support & EOL dates for every release
OpenSSL · Infrastructure · 5 supported · 9 end-of-life · updated June 2026 · what is end-of-life? →
This is when each OpenSSL release line stops receiving security updates. 5 release lines are still supported — the next to reach end-of-life is OpenSSL 3.0 on 7 Sept 2026. Running an end-of-life version means new vulnerabilities stay unpatched.

Which OpenSSL version should I run?
The safest choice is the latest supported release, 4.0.1. If you're on an end-of-life line, plan an upgrade to a supported one before security updates stop. See OpenSSL's full security status →

OpenSSL end-of-life — frequently asked
What OpenSSL versions are still supported?
As of June 2026, these OpenSSL release lines still receive security updates: 3.5, 4.0, 3.6, 3.4, 3.0. The latest supported release is 4.0.1. Versions older than these (3.3, 3.2, 3.1, 1.1.1, 1.0.2, 1.1.0, 1.0.1, 1.0.0, 0.9.8) are end-of-life and no longer patched.
When does OpenSSL 3.0 reach end of life?
OpenSSL 3.0 reaches end-of-life on 7 Sept 2026 — about 3 months away. After that date it stops receiving security patches.
Is OpenSSL end-of-life?
No — OpenSSL still has supported release lines (3.5, 4.0, 3.6, 3.4, 3.0). But individual older versions are end-of-life, so what matters is the specific version you run.
How do I know when my OpenSSL version reaches end of life?
Check the version you run on its product page, or monitor OpenSSL on IsItPatched to get an email alert before the release line you use reaches end-of-life — so you can upgrade in time.
