wodKey Load method - WeOnlyDo Discussion board

Linear

Hi,
I have one further problem with wodSFTP in Embarcadero Delphi.

I successfully can parametrize the SFTP component and use a Putty-generated private key file (.ppk) for authentication to connect to an SFTP-Server.
The wodKeys manual states that instead of loading the key from a file it is also possible to directly load it from a string with the load method, but I am not able to do this:

var v: variant;
KeyData:variant; //I also tried string;
begin
KeyData := '-----BEGIN RSA PRIVATE KEY-----.......';
CoInitialize(nil);
SFTP := TwodSFTP.Create(nil);
SFTP.Hostname := xxx;
SFTP.Login := xxx;
SFTP.Authentication := 2;
SFTP.Timeout := 10000;
SFTP.Blocking := false;
SSHKey := CreateOleObject('WeOnlyDo.Keys.1');
SSHKey.Load(KeyData);

Here a EOLESysError exception (wrong variable type) is raised and I cannot continue.

So how can I successfully use an RSA private key that is stored in a string?

Thanks,
Bernhard

Hi Bernhard,

When you declared key as string, did you receive sam error?

Are you able to load key from file?

Any chance you can send us EXE that demonstrates the problem, with sample key? We would like to debug it under the hood to see why this happens.

Thanks,
Jasmine

Hi,
when using Load with a string I get "Failed to import string from file' error...
I will prepare an exe but this will take some time!

Thanks for your excellent support!
Regards, Bernhard

Thank you very much for the rapid responses. I was a little nervous about dealing with a company that is on a different continent from me. You have proven my concerns to be unfounded.
