Using Public-Key Authentication from Windows Client to z/OS Server
The instructions apply to SSH Tectia Client 5.1 and later. For more information, see SSH Tectia Client 5.x User Manual.
Using Graphical User Interface
On Windows, you can use the SSH Tectia Key Generation wizard to generate a key pair.
New keys are generated in the SSH Tectia Configuration tool. Select the Keys and Certificates page under User authentication and click New Key... to start the Key Generation wizard. The wizard will generate two key files, your private key and your public key. The private key file has no file extension, and the public key has the same base file name as the private key, but with .pub as the file extension. The key files will be stored on your local computer, in the user profile directory.
Public keys can be uploaded automatically to servers that have the SFTP subsystem enabled. The automatic upload can be done on the Keys and Certificates page of SSH Tectia Configuration tool. Select your key pair from the list and click Upload. The Upload Public Key dialog box opens.
Define the conversion parameters directly in the Destination folder path as shown in Figure Uploading the public key below.
Figure : Uploading the public key
Click Upload to start the upload.
If you are already connected to the remote server host, the key upload starts immediately. If you are not connected, you will be prompted to authenticate to the server (by default with password).
Make sure that public-key authentication is allowed in the Connection Broker configuration on Client, in the default settings and in the relevant connection profile (it is allowed by default).
Using Command-Line Tools
The key pair can also be generated and transferred to the z/OS server by using command-line tools.
Create a key pair using ssh-keygen-g3. For non-interactive use, the key can be generated without a passphrase with the -P option.
C:\>ssh-keygen-g3 -t rsa -b 1024 -P win_key
