Read it at the original source: ## Questions this post answers ### Has GitHub disabled SHA-1 in HTTPS for github.com yet? Yes, GitHub disabled SHA-1 in HTTPS for github.com and partner CDNs, including GitHub Enterprise Cloud and GitHub Enterprise Cloud with Data Residency, on September 15, 2026, as previously scheduled. GitHub Enterprise Server is unaffected and continues to support SHA-1 in HTTPS. _Teams tracking TLS and HTTPS deprecations across their toolchain can follow updates like this one on daily.dev._ ### Does the SHA-1 HTTPS sunset affect GitHub Enterprise Server? No, GitHub Enterprise Server is explicitly unaffected by the SHA-1 in HTTPS sunset. The change applies only to github.com and partner CDNs, including GitHub Enterprise Cloud and GitHub Enterprise Cloud with Data Residency, so self-hosted Enterprise Server instances retain SHA-1 support in HTTPS. _Admins comparing GitHub Enterprise Cloud versus Server security posture can find changes like this via daily.dev._ ## Similar posts on daily.dev - [Sunsetting SHA-1 in HTTPS on GitHub](https://daily.dev/posts/sunsetting-sha-1-in-https-on-github-fwvxha6ko) · GitHub Changelog · 2 upvotes · 0 comments --- Tags: [#github](https://daily.dev/tags/github), [#cryptography](https://daily.dev/tags/cryptography) [View this post on daily.dev](https://daily.dev/posts/sha-1-in-https-on-github-sunset-kwc1ddgt5) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"SHA-1 in HTTPS on GitHub sunset","url":"https://daily.dev/posts/sha-1-in-https-on-github-sunset-kwc1ddgt5","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/sha-1-in-https-on-github-sunset-kwc1ddgt5"},"datePublished":"2026-09-15T16:58:13.528Z","dateModified":"2026-09-15T16:58:34.001Z","description":"GitHub has disabled SHA-1 in HTTPS for github.com and partner CDNs, including GitHub Enterprise Cloud and GitHub Enterprise Cloud with Data Residency,...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/34f4a8b6a99dc2bd1aca6124143d4bcf?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/34f4a8b6a99dc2bd1aca6124143d4bcf?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"GitHub Changelog","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"GitHub Changelog","logo":"https://media.daily.dev/image/upload/t_logo,f_auto/v1/logos/15004b7835da4d89b02b115871f0f6dc","url":"https://daily.dev/sources/github_updates"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/sha-1-in-https-on-github-sunset-kwc1ddgt5","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"github,cryptography","timeRequired":"PT1M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"GitHub Changelog","item":"https://daily.dev/sources/github_updates"},{"@type":"ListItem","position":3,"name":"SHA-1 in HTTPS on GitHub sunset"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/sha-1-in-https-on-github-sunset-kwc1ddgt5#faq","mainEntity":[{"@type":"Question","name":"Has GitHub disabled SHA-1 in HTTPS for github.com yet?","acceptedAnswer":{"@type":"Answer","text":"Yes, GitHub disabled SHA-1 in HTTPS for github.com and partner CDNs, including GitHub Enterprise Cloud and GitHub Enterprise Cloud with Data Residency, on September 15, 2026, as previously scheduled.
