c＃的RSA公共密钥的公钥＃
问题描述：
我需要在c＃项目中使用RSA密码来将ecrypted数据发送到服务。 服务给了我这样一个公共密钥：c＃的RSA公共密钥的公钥＃

-----END PUBLIC KEY-----
我怎样才能将其转换为Base64字符串与此代码使用？
public static string EncryptData(string publicKey, string clearText)
{
IBuffer keyBuffer = CryptographicBuffer.DecodeFromBase64String(publicKey);
AsymmetricKeyAlgorithmProvider asym = AsymmetricKeyAlgorithmProvider.OpenAlgorithm(AsymmetricAlgorithmNames.RsaPkcs1);
CryptographicKey key = asym.ImportPublicKey(keyBuffer, CryptographicPublicKeyBlobType.Capi1PublicKey);
IBuffer plainBuffer = CryptographicBuffer.ConvertStringToBinary(clearText, BinaryStringEncoding.Utf8);
IBuffer encryptedBuffer = CryptographicEngine.Encrypt(key, plainBuffer, null);
byte[] encryptedBytes;
CryptographicBuffer.CopyToByteArray(encryptedBuffer, out encryptedBytes);
return Convert.ToBase64String(encryptedBytes);
}
答
我找到解决方案，很容易： 我需要使用：
CryptographicKey key = asym.ImportPublicKey(keyBuffer, CryptographicPublicKeyBlobType.X509SubjectPublicKeyInfo);
