About this tag
Client certificate authentication in Windows environments involves mutual TLS (mTLS) workflows, IIS configuration, and certificate handling. Discussions cover TLS 1.3 breaking client certificate requests in IIS Express on Windows 11, with workarounds for developers. UWP networking APIs like System.Net.Http.HttpClient and Windows.Web.Http.HttpClient support client certificates for secure communication. Issues such as Internet Explorer prompting for client certificate selection, FTP login errors with IIS 7.5 when client certificate authentication is enabled, and automatic extraction of root CA for client certificates in Windows 7 are also addressed. These threads highlight practical challenges and solutions for client certificate deployment and troubleshooting.
