Key Points

  • The 1.19.0 release adds support in ClientCertificateCredential to reference certificates in the platform certificate store via a path such as cert:/CurrentUser/My/Thumbprint, instead of loading a certificate from disk.
  • This mechanism enables loading certificates from platform stores like Windows Certificate Store and macOS KeyChain, improving security and portability.
  • The certificate-store path feature is contributed by the community member fowl2.
  • The release also updates dependencies: Microsoft.Identity.Client and Microsoft.Identity.Client.Extensions.Msal to version 4.83.1.

1.19.0 (2026-03-11)

Features Added

  • Added support in ClientCertificateCredential to specify a path in the form of cert:/StoreLocation/StoreName/Thumbprint to refer to a certificate in the platform certificate store - such as the Windows Certificate Store on Windows, and the KeyChain on MacOS - instead of a file on disk. For example to load a certificate from the "My" store in the "CurrentUser" location use the path cert:/CurrentUser/My/E661583E8FABEF4C0BEF694CBC41C28FB81CD870 (A community contribution, courtesy of fowl2).

Other Changes

  • Updated Microsoft.Identity.Client and Microsoft.Identity.Client.Extensions.Msal dependencies to version 4.83.1.
