我试图解密客户端提供此示例文件，使用一个名为PgpDecrypt类。 但是，当代码涉及到这一行：
Stream clear = pbe.GetDataStream(privKey);
它返回一个错误： 异常解密密钥
这里是我的解密代码：
PgpDecrypt test = new PgpDecrypt(string.Concat(pathh, "TestDecryptionFile"),
string.Concat(pathh, "mypgpprivatekey.key"),
"mypassphrase",
@"d:/test/",
string.Concat(pathh, "clientpublickey.key"));
FileStream fs = File.Open(string.Concat(pathh, "TestDecryptionFile"), FileMode.Open);
test.Decrypt(fs, @"d:\test\");
我使用BouncyCastle的我的第三方库的.NET。
任何想法来解决，这将是一个很大的帮助。 提前致谢！
如果你按照BouncyCastle的类PGPEncrypt，PGPDecrypt和PGPEncryptionKeys ...
根据PGPEncryptionKeys类，添加这个方法：
/// <summary>
/// Return the last key we can use to decrypt.
/// Note: A file can contain multiple keys (stored in "key rings")
/// </summary>
private PgpSecretKey GetLastSecretKey(PgpSecretKeyRingBundle secretKeyRingBundle)
{
return (from PgpSecretKeyRing kRing in secretKeyRingBundle.GetKeyRings()
select kRing.GetSecretKeys().Cast<PgpSecretKey>()
.LastOrDefault(k => k.IsSigningKey))
.LastOrDefault(key => key != null);
}
仍然是PgpEncryptionKeys类中，确保ReadSecretKey方法如下：
private PgpSecretKey ReadSecretKey(string privateKeyPath, bool toEncrypt)
{
using (Stream keyIn = File.OpenRead(privateKeyPath))
using (Stream inputStream = PgpUtilities.GetDecoderStream(keyIn))
{
PgpSecretKeyRingBundle secretKeyRingBundle = new PgpSecretKeyRingBundle(inputStream);
PgpSecretKey foundKey = toEncrypt ? GetFirstSecretKey(secretKeyRingBundle) : GetLastSecretKey(secretKeyRingBundle);
if (foundKey != null)
return foundKey;
}
throw new ArgumentException("Can't find signing key in key ring.");
}
