Hello,
I work with the C ++ Builder Xe

ScSSHClient1->; HostName = "111. 111. 111. 11";
Key->; KeyName = ScSSHClient1->; HostName;
Key->; ImportFrom ("C: \\temp \\PublicKey. TXT");
ScSSHClient1->; Authentication=atPublicKey;
ScSSHClient1->; PrivateKeyName = Key->; KeyName;
ScSSHClient1->; HostKeyName = Key->; KeyName;
ScSSHClient1->; Connect ();

I get the following error message:
The Data can Be signed by a non private key

The Key functions with Firefox->; FireFtp
Can somebody help me?

The error most likely occurs due to that in the TScSSHClient.PrivateKeyName property you have specified not the private key, but the public one. This property must contain the private key and its value must differ from the TScSSHClient.HostKeyName property value.
To solve the issue, please specify the private key in the TScSSHClient.PrivateKeyName property and try to reproduce the error.

I have exchanged private key for the publicly Key.
the same error message
Which value needs TScSSHClient. HostKeyName?

The TScSSHClient.HostKeyName property should contain the name of the server public key that is stored in KeyStorage. See more details about this property in SecureBridge help: https://www.devart.com/sbridge/docs/tsc ... eyname.htm
Please make sure you have specified the private key in the TScSSHClient.PrivateKeyName property. For this, you can use the TScKey.IsPrivate property. See more details about this property in SecureBridge help: https://www.devart.com/sbridge/docs/tsc ... rivate.htm

I go crazy

I have 3 things

1. IP Adress 111.111.111.11
2. 2. UserName DD
3. 3 PrivateKey FileName= PrivateKey.TXT
-----BEGIN RSA PRIVATE KEY-----
???????????????????????????????
?????????????J+I/hQIL2h8MDgXQ==
-----END RSA PRIVATE KEY-----

any more I do not need



TScKey *Key = ScFileStorage1->Keys->FindKey(ScSSHClient1->HostName);
Key = new TScKey(NULL);

ScSSHClient1->; HostName = "111. 111. 111. 11";
ScSSHClient1->; User = DD
Key->; KeyName = ScSSHClient1->HostName;
Key->ImportFrom("C:\\temp\\PrivateKey.TXT") ;

if(Key->IsPrivate) {ShowMessage("private");}
else {ShowMessage("not private");}

Answer = private

ScSSHClient1->Connect();
Answer = Private key not found

if nobody can help me ?

Please check whether the issue is reproduced when connecting to SSH server using our SSHClientApp demo project. You can find the SSHClientApp project in the %SecureBridgeDemos%\SSHClientApp directory. %SecureBridgeDemos% is the SecureBridge Demo projects installation path on your computer.
If the issue is not reproduced on our SSHClientApp demo project, please compose a complete sample demonstrating the described behavior and send it to viktorv*devart*com, in order for us to be able to answer you in more detail.

hello, viktor
many thanks for your help
