SHA-1 in HTTPS on GitHub sunset
GitHub has disabled SHA-1 in HTTPS for github.com and partner services as previously announced. Users must update their systems to use modern TLS cipher suites to maintain connectivity.
Previously we announced we would be disabling SHA-1 in HTTPS for GitHub on September 15th, 2026.
Following the planned schedule, GitHub has disabled SHA-1 in HTTPS for github.com and partner CDNs, including GitHub Enterprise Cloud and GitHub Enterprise Cloud with Data Residency. GitHub Enterprise Server is unaffected. Please see the previous announcement for more information.
