error-strust.jpgHello all,

I am trying to setup an HTTPS communication with SAP.
I used the STRUST transaction code in SAP GUI. Then I am trying to Import a certificate as per document in the below link:

While trying to import the certificate I am getting below error:
"SSF kernel error: invalid parameter"

I have tried this The error is same for both Binary and Base64 file formats. I have attached the screenshot as well for reference.

I have few questions here:

1. Is the file given in the 'File Path' of correct format ? This file is generated using the 'Keytool' utility. I have also tried this with the Self Signed Certificate created on Windows 7.

2. The document says 'Most certificates will be delivered in Base64 format by the CA.' How can I identify the CA authority?

you're trying to import the whole JAVA Keystore which is not supported. Please use software like KeyStore Explorer to extract certificates to separate files (as X.509 certificates) and then import it.

Best regards

Hi Bartosz,

Thanks for your quick response.

I have tried using different files viz.

1..jks file, which is created using the keytool tool.

2..cer file, which is generated from websphere.

3..pfx file, which is a self-signed certificate generated on windows from IIS.

Still I am getting same error for all i.e. "SSF kernel error: invalid parameter"
