Specificationhttps://www.rfc-editor.org/rfc/rfc9155.html Summary Chrome is removing support for signature algorithms using SHA-1 for server signatures during the TLS handshake. This does not affect SHA-1 support in server certificates, which was already removed, or in client certificates, which continues to be supported. SHA-1 can be temporarily re-enabled via the temporary InsecureHashesInTLSHandshakesEnabled enterprise policy. This policy will be removed in Chrome 123.

However, we cannot disambiguate between a flaky first connection, and actually requiring SHA1. We expect the actual amount is lower. *Gecko*: Positive (https://github.com/mozilla/standards-positions/issues/812 ) *WebKit*: Positive (https://github.com/WebKit/standards-positions/issues/196 ) *Web developers*: No signals *Other signals*: WebView application risks Does this intent deprecate or change behavior of existing APIs, such that it has potentially high risk for Android WebView-based applications?

Please list open issues (e.g. links to known github issues in the project for the feature specification) whose resolution may introduce web compat/interop risk (e.g., changing to naming or structure of the API in a non-backward-compatible way).
