The oid of the private key is: "1.3.101.112" which corresponds to the RFC oid for ED25510 If you load in a new X509Certificate2 from a file by calling the public . The following code should be used instead. So this is great, however I have to issue an openssl command to make a pfx file from the Certificate and the Private Key, then make up some password. Would you have any idea why this happens? How a top-ranked engineering school reimagined CS curriculum (Ep. Since I'm specifying StoreLocation.LocalMachine, they go to: Then I have a problem. Why did DOS-based Windows require HIMEM.SYS to boot? It's very simple, small and easy to use. That's a big problem because the file is created using GetTempFile. You might have just loaded the certificate from a blob with the key. What you really should do is to read contents of the file and convert it to Base64 string without touching X509Certificate2 class. For this use: I would recommend naming files with "includesprivatekey" to help you manage the permissions you keep with this file. All it takes for it to fail is to try calling the constructor like this This can be beneficial to other community members reading this thread.

If you have any compliments or complaints to on .NET Framework (but not .NET Core) if your private key is RSACryptoServiceProvider or DSACryptoServiceProvider you can use cert.PrivateKey = key, but that has complex side-effects and is discouraged. using (X509Certificate2 pubOnly = new X509Certificate2 ("myCert.crt")) using (X509Certificate2 pubPrivEphemeral = pubOnly.CopyWithPrivateKey (privateKey)) { // Export as PFX and re-import if you want "normal PFX private key lifetime . This returns a new instance of X509Certificate2 which knows about the private key. There are also X509Certificate2.CreateFromEncryptedPem and X509Certificate2.CreateFromEncryptedPemFile if the contents is encrypted.

Also, it is important that I export from a .pfx file and import it later to a .pfx file. macOS has ed25519 APIs in CryptoKit so in theory that could be done on new enough systems (10.15+). They might be stored under the Keys subkey for the store, or, they might be stored on disk. How can I control PNP and NPN transistors together from one pin? Is this only for Windows and .NET Framework? Started looking into what would we needed to implement it properly.
