how to get public key from bytes? for example, I have public key (generated with EC algorithm, curve "secp256r1") and its encoded bytes on java, How can I create public key from these bytes in c#?
There are different methods to fetch the key from the vault. I used the following for the same.
var secret = keyVaultClient.GetSecretAsync(vaultAddress, "Honeywellpkiofflinetokenprime256v1cert").GetAwaiter().GetResult();
X509Certificate2Collection exportedCertCollection = new X509Certificate2Collection();
exportedCertCollection.Import(Convert.FromBase64String(secret.Value));
X509Certificate2 certFromSecret = exportedCertCollection.Cast<X509Certificate2>().Single(s => s.HasPrivateKey);
var publickeybyte = certFromSecret.GetPublicKey();
var publicekeybyte = certFromSecret.GetPublicKeyString();
var PublicKeyCNG= certFromSecret.GetECDsaPublicKey();
var privateECDsa = LoadPrivateKey(FromHexString(privateKey));
var publiccECDsa = LoadPublicKey(FromHexString(publicKey));
now you can use the same key to verify your signed information.
