Ошибка при декодировании заполнения oaep windows admin center

Gateway Version: 1.3.2204.19002

To Reproduce
Steps to reproduce the behavior:

  1. Install Windows Admin Center on a brand new Windows Sever 2022 Core (AD-connected)
  2. Attempt to add a new Windows Server 2022 Core server instance from AD to Admin Center
  3. Connect to newly added server
  4. See error «Error occurred while decoding OAEP padding.»

Note: It’s also impossible to connect straight from the «Add» wizard as no credentials seem to be working.

Expected behavior
Connect to server.

Screenshots & Additional context

I’d love to provide more information but this whole Windows Admin Center installation is brand new and I barely know how to move around it. Suffice to say… it’s not nearly as easy as I had hoped.

While decrypting text using RSACryptoServiceProvider.Decrypt, I am getting the error:

Error occurred while decoding OAEP padding.

Here’s my code:

CspParameters cspParam = new CspParameters();

cspParam = new CspParameters();

cspParam.Flags = CspProviderFlags.UseMachineKeyStore;

clsCertificates cc = new clsCertificates();

string a = "";

cc.OpenStoreIE(ref a);

cc.SetProperties();

X509Certificate2 cert = new X509Certificate2();

cert = cc.x509_2Cert;

RSACryptoServiceProvider rsa = new RSACryptoServiceProvider(cspParam);

//to gentrate private and public keys from the certificate

rsa.FromXmlString(cert.PublicKey.Key.ToXmlString(false));


String publicKey = rsa.ToXmlString(false); // gets the public key 
String privateKey = rsa.ToXmlString(true); // gets the private key working if paramter is false if true give error key is not valid for use in specified state

Response.Write("<Textarea rows=10 cols=100>PUBLIC: " + publicKey + "</TextArea>");

Response.Write("<Textarea rows=10 cols=100>PRIVATE: " + privateKey + "</Textarea>");

Response.Write("<BR>Encrypting the string "HelloThere" with the public Key:<BR>");

String str = "HelloThere";

RSACryptoServiceProvider RSA2 = new RSACryptoServiceProvider(cspParam);



//---Load the Public key---

RSA2.FromXmlString(publicKey);

//working with the folowing line instead of above but i need the keys of he certificte

//RSA2.ToXmlString(true);

Byte[] EncryptedStrAsByt = RSA2.Encrypt(System.Text.Encoding.Unicode.GetBytes(str), true);

String EncryptedStr = System.Text.Encoding.Unicode.GetString(EncryptedStrAsByt);

Response.Write("<Textarea rows=10 cols=100>Encrypted String: " + EncryptedStr + "</Textarea>");

Response.Write("<BR>Decrypting the Encrypted String with the Private key:<BR>");



RSACryptoServiceProvider RSA3 = new RSACryptoServiceProvider(cspParam);



//---Load the Private key---

RSA3.FromXmlString(privateKey);

//working with the folowing line instead of above but i need the keys of he certificte

//RSA3.ToXmlString(true);

Byte[] DecryptedStrAsByt = RSA3.Decrypt(EncryptedStrAsByt, true );//Error if true then error is error occured while decoding the OAE$P padding and if false then error is bad key i am using windows xp so it should be true.

String DecryptedStr = System.Text.Encoding.Unicode.GetString(DecryptedStrAsByt);

Response.Write("<Textarea rows=10 cols=100>Decrypted String: " + DecryptedStr + "</Textarea>");

The above is works if I am not using the keys of my digital certificate. but if the keys are from the digital certificate, I get the OAEP padding error.

Note: This question is in continuation of the Error occurred while decoding OAEP padding question

A common mistake is to try to decrypt using the public key.

I ran into this exact problem. UnicodeEncoding.GetBytes is not always the inverse of UnicodeEncoding.GetString.

byte[] a = new byte[32];

RandomNumberGenerator gen = new RNGCryptoServiceProvider();
gen.GetBytes(a);

UnicodeEncoding byteConverter = new UnicodeEncoding();

byte[] b = byteConverter.GetBytes(byteConverter.GetString(a));

//byte array 'a' and byte array 'b' will not always contain the same elements.

This is why RSACryptoServiceProvider.Decrypt fails. A lot of encrypt/decrypt examples on the web use Unicode encoding. Do not use Unicode encoding. Use Convert.FromBase64String and Convert.ToBase64String instead.

This error normally indicates you are using a public key to decrypt, while you should be using a private key for decryption. Give it a try.

In my case the error has been caused by wrong padding settings.

Error: RSA decrypt: error:0407A079:rsa routines:RSA_padding_check_PKCS1_OAEP:oaep decoding error

I had openssl_public_encrypt() with OPENSSL_PKCS1_PADDING as a default value in PHP and keypair.decrypt() with the default value RSA_PKCS1_OAEP_PADDING in node-rsa.

So don’t forget to check these options too.

FYI, you can still be (en/de)crypting in the right key sequence (encr:pub key, decr:priv key) — i.e. can still get this error decrypting with a private key — it just may be the wrong private key (i.e. from another cert/key pair), not the one paired w/ the pub key with which u encrypted initially. If u turn off OAEP padding and get a «bad data» exception, that’s another indication.

We were getting this issue when we were using the wrong key for decryption.

RSA encryption may result non readable character, make sure not to cut the string due to special character indicating end of something during write/read the encryption result; e.g you must not use strlen for it will stop when encounter a » in the string.

Another thing to check: it was giving me this error, on the decrypt operation, as a result of forgetting to pass the public key into the RSACryptoServiceProvider for the encrypt operation.

    System error 5 has occurred even as admin — (cmd) Windows 10

    My system is Windows 10 Pro x64, with the latest updates applied.

    When I try to execute any «net» command in cmd (eg: net stop TeamViewer, net users, etc’) I get the error «System error 5 has occurred. Access is denied.»

    I have researched for hours and did every possible solution I saw mentioned anywhere but still no luck.
    Here are a few facts:

    1. I opened the cmd with admin rights (see screenshot below)
    2. I am the sole PC user with full admin rights.
    3. This happens even if I disable Windows Firewall.
    4. My UAC is disabled and in the registry, EnableLUA is set to 0.
    5. Created a new administrator account and tested it there. Same issue.
    6. Also in Windows Built-in administrator account, the issue happens.

    How can I give myself access to run net commands?

  • Добрый день, коллеги!

    Пытаюсь настроить работу WAC (2009)  WinRM for HTTPS, провел подготовительные работы на удаленном ПК согласно

    статье. Но при попытке подключиться выходит следующая ошибка и не могу понять почему: 

    Connecting to remote server srv01.contoso.local failed with the following error message : The server certificate on the destination computer (srv1.contoso.local:5986) has the following errors: The SSL certificate could not be checked for revocation. The server used to check for revocation might be unreachable. For more information, see the about_Remote_Troubleshooting Help topic.

    Проверил CRL доступны, в Enterprise PKI тоже все ОК, в чем проблема не могу понять, есть у кого соображения по этому поводу?

    Даже сам на себя через WAC не получается зайти :-(, когда-то пробовал данный функционал все без проблем работало, может глюк новой версии?

  • Действительно как только я настроил OCSP и выпустил новый сертификат все заработало.
