Enforce 398-day validity for certificates issued on-or-after 2020-09-01

Enforce publicly trusted TLS server certificates have a
lifetime of 398 days or less, if they are issued on or after
2020-09-01.

Certificates that violate this will be rejected with
ERR_CERT_VALIDITY_TOO_LONG and will be treated as misissued.

Logo Chromium

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.

The project's web site is https://www.chromium.org.

Documentation in the source is rooted in docs/README.md.

Learn how to Get Around the Chromium Source Code Directory Structure .

For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.
