Obtain the public key's hash from a X509Certificate2












0















I hold a X509Certificate2 object, I can access the public key via the PublicKey property. For a different API I need to obtain the public key's SHA-1 hash. Is there a simple way to get it from the PublicKey property?



I tried the following:



var sha1 = SHA1.Create().ComputeHash(signerCert.PublicKey.???)


But what to put instead of the "???". It doesn't look like there is some kind of "Raw" data property.






c# .net x509certificate

          The answer seems to be signerCert.GetPublicKey() instead of accessing the PublicKey property directly.
