SFTP key based Authentication for Custom Module

[former_member207622]

Hi Folks ,

I am using  Key based authentication in my receiver SFTP adapter.

I also have a custom module which will place file on SFTP  server and at the same time Ack file on NFS system.

Can anyone let me know how to access the key store for certificate and private key in the custom module as ( certificate and private key is located in NWA )

I would require that in module for authentication purpose.

Any help is appreciated

Thanks

Hi Team/Praveen

I am able to access the private key through the code given above from the keystore.

Now I want to use this private key in this method -

jsch.addIdentity

But for this parameters should be private key path .

Can you please let me know how to proceed ahead for authentication. I have already supplied the customer the public key .

Thanks

How was it solved? How did you convert the java.security.PrivateKey to the format Jsch wants to have?

Hi Ninad,

You can find the help document here Accessing the AS Java Keystore - SAP NetWeaver Process Integration - SAP Library

Sample adapter have the example code for this.

SAPSecurityResources secRes = SAPSecurityResources.getInstance();
  KeyStoreManager ksMgr = secRes.getKeyStoreManager(PermissionMode.SYSTEM_LEVEL, new String[]{ "sap.com/com.sap.aii.adapter.sample.ra" } );
  java.security.KeyStore ks = ksMgr.getKeyStore(privKeyView);
  ISsfProfile privKeyProf = ksMgr.getISsfProfile(ks, privKeyAlias, null); //Since code based permission is used no password needs to be supplied
  java.security.PrivateKey privKey = privKeyProf.getPrivateKey();
