BouncyCastle create AsymmetricCipherKeyPair from existing keys?
I have two AssymetricAlgorithm
开发者_JAVA技巧 RSA keys that I have pulled out of a certificate that was in my keystore. One is the Public Key and the other the Private. Is there a way of getting this keypair into a BouncyCastle AsymmetricCipherKeyPair? BouncyCastle's AsymmetricCipherKeyPair
expects a public and private AsymmetricKeyParameter
however I have no way of getting my Private key without it being an instance of AssymetricAlgorithm
.
The answer to this lies here:
Get Private Key from BouncyCastle X509 Certificate? C#
I think this will help if key is marked as exportable
RSACryptoServiceProvider key = (RSACryptoServiceProvider)X509Certificate2object.PrivateKey;
RSAParameters rsaparam = key.ExportParameters(true);
AsymmetricCipherKeyPair keypair = DotNetUtilities.GetRsaKeyPair(rsaparam);
