问题：
如何在充气城堡中装载推杆钥匙
郜谦
我在玩加密。我被困在用BouncyCastle加载密钥上。密钥是由PuTTYgen（SSH-2 RSA 4096位）生成的。也许有其他方法可以加载它吗？
PuTTY-User-Key-File-2: ssh-rsa
Encryption: aes256-cbc
Comment: rsa-key-20160508
Public-Lines: 12
我得到：
“System.IO”类型的未处理异常。BouncyCastle.Crypto中出现“IOException”。dll＜br＞其他信息：意外的内容结束标记“”

添加：
我可以生成一个公钥，也可以加载一个未加密的私钥(https://rietta.com/blog/2012/01/27/openssl-generating-rsa-key-from-command/)
openssl genrsa-des3-out是私有的。pem 4096
openssl rsa-私有。pem-输出pem-发布-输出public.pem
OpenSSL RSA-in private . PEM-out private _ encrypted . PEM-out form PEM
var publickey = Convert.FromBase64String(pubkey);
var privatekey = Convert.FromBase64String(prikey);
var asnprivate = Org.BouncyCastle.Asn1.Asn1Object.FromStream(new MemoryStream(privatekey));
var privStruct = new Org.BouncyCastle.Asn1.Pkcs.RsaPrivateKeyStructure((Org.BouncyCastle.Asn1.Asn1Sequence)asnprivate);
AsymmetricKeyParameter publicAsymmetricKey = PublicKeyFactory.CreateKey(publickey);
但是我无法加载加密的私钥...

有了openssl PEM，我能够让它工作。我继续寻找如何加载受保护的私钥。

油灰。ppk密钥格式是PuTTY专有的。
我很确定Bouncy castle中不支持.ppk文件。
您需要将您的密钥转换为OpenSSH格式。为此，请参阅如何将使用PuttyGen(Windows)生成的SSH密钥对转换为ssh-agent和KeyChain(Linux)使用的密钥对。
