∟"not an RSA key" - Encryption Failed in SoapUI

This section provides a tutorial example of SOAP message encryption failed with 'not an RSA key' with SoapUI, if a certificate entry with a DSA public key is specified in the WS-Security configuration.

With the "Encryption" configuration created, we can continue to try to generate a SOAP request message that is encrypted with SoapUI.

1. Right-click on "Hello" and select "New Request". The request screen is displayed with a new SOAP test request message.

2. Click on "Auth" below the request message area on the request screen, The authorization area is displayed.

3. Select "Add a New Authorization". Then select "Basic" as the "Type". Basic authorization fields are displayed.

4. Set "Outgoing WSS" to "Encryption", which represents the "Encryption" WS-Security configuration created in the previous tutorial.

5. Click on "Submit request ..." icon in the icon bar on the request screen. The response message will be displayed.

6. Click on the "Raw" vertical tab. Unfortunately, the SOAP message is not encrypted.

7. Click on the "Error Log" in the bottom bar. You will see the following error message:

The error message tells us that SoapUI only supports RSA public key on SOAP message encryption. My public key in "mycertificate" was generated with the DSA algorithm. We need to get a RSA public key certificate to continue our test.
