- This update addresses a change that affects how you use the X509Certificate, X509Certificate2, or X509Certificate2Collection classes. When you use them to import a PKCS#12 blob that contains a private key, the calling application might get an exception. The exception message is, “System.Security.Cryptography.CryptographicException: PKCS12 (PFX) without a supplied password has exceeded maximum allowed iterations. See https://go.microsoft.com/fwlink/?linkid=2233907 for more information.” To learn more, seeKB5028608.
