c# - 生成 pgp key 时出现问题？

Question

我正在使用 RSACryptoServiceProvider 我已经生成了公钥和私钥。它生成的 key 格式如下:

公钥:

<RSAKeyValue>
    <Modulus>m9bAoh2...eGNKYs=</Modulus>
    <Exponent>AQAB</Exponent>
</RSAKeyValue> 

私钥:

<RSAKeyValue>
    <Modulus>m9bAo...ZAIeGNKYs=</Modulus>
    <Exponent>AQAB</Exponent>
    <P>xGj/UcXs...R1lmeVQ==</P>
    <Q>yx6e18aP...GXzXIXw==</Q>
    <DP>NyxvnJ...1xAsEyQ==</DP>
    <DQ>La17Jycd...FhApEqwznQ==</DQ>
    <InverseQ>JrG7WCT...Hp3OWA==</InverseQ>
    <D>RdWsOFn....KL699Vh6HK0=</D>
</RSAKeyValue>

但是使用 PGP Desktop 我生成了这样的 key -

公钥:

mQCNBEoOlp8BBACi/3EvBZ83ZduvG6YHu5F0P7Z3xOnpIsaPvTk0q+dnjwDUa5sU 
lEFbUZgDXSz7ZRhyiNqUOy+IG3ghPxpiKGBtldVpi33qaFCCEBiqsxRRpVCLgTUK 
HP2kH5ysrlFWkxTo 
=a4t9 

私钥:

lQHgBEoOlp8BBACi/3EvBZ83ZduvG6YHu5F0P7Z3xOnpIsaPvTk0q+dnjwDUa5sU 
lEFbUZgDXSz7ZRhyiNqUOy+IG3ghPxpiKGBtldVpi33qaFCCEBiqsxRRpVCLgTUK 
waBnEitQti3XgUUEZnz/rnXcQVM0QFBe6H5x8fMDUw== 
=CVPD 

因此，当我传递由 PGP Desktop 生成的 key 时，它能够完美地进行加密和解密，但是当我传递由 RSACryptoServiceProvider 生成的 key 时，我无法加密和解密？

谁能告诉我如何在 PGP 生成的模式中生成 key ？

使用 bouncycaSTLe c# 库这就是我生成 key 对的方式。

public void GenerateKey(string username, string password, string keyStoreUrl)
        {
            IAsymmetricCipherKeyPairGenerator kpg = new RsaKeyPairGenerator();
            kpg.Init(new RsaKeyGenerationParameters(BigInteger.ValueOf(0x13), new SecureRandom(), 1024, 8));
            AsymmetricCipherKeyPair kp = kpg.GenerateKeyPair();

            FileStream out1 = new FileInfo(string.Format("{0}secret.asc", keyStoreUrl)).OpenWrite();
            FileStream out2 = new FileInfo(string.Format("{0}pub.asc", keyStoreUrl)).OpenWrite();

            ExportKeyPair(out1, out2, kp.Public, kp.Private, username, password.ToCharArray(), true);

        }

private static void ExportKeyPair(
            Stream secretOut,
            Stream publicOut,
            AsymmetricKeyParameter publicKey,
            AsymmetricKeyParameter privateKey,
            string identity,
            char[] passPhrase,
            bool armor)
        {
            if (armor)
            {
                secretOut = new ArmoredOutputStream(secretOut);
            }

            PgpSecretKey secretKey = new PgpSecretKey(
                PgpSignature.DefaultCertification,
                PublicKeyAlgorithmTag.RsaGeneral,
                publicKey,
                privateKey,
                DateTime.Now,
                identity,
                SymmetricKeyAlgorithmTag.Cast5,
                passPhrase,
                null,
                null,
                new SecureRandom()
                //                ,"BC"
                );

            secretKey.Encode(secretOut);

            secretOut.Close();

            if (armor)
            {
                publicOut = new ArmoredOutputStream(publicOut);
            }

            PgpPublicKey key = secretKey.PublicKey;

            key.Encode(publicOut);

            publicOut.Close();
        }

并且它以装甲 ASCII 格式生成私钥和公钥，例如。
