No public key with encryption capability

Dear all,

maybe the question is simple, but unfortunately I haven't no clue here.

If I did a test the PGP Module in SAP PI, I get now always the error "No public key with encryption capability" back.

I create a public key and put them into /usr/sap/<SID>/DVEBMGSXX/sec.

The public key contains only the key, no certificate...

I administrate the Receiver Channel as well.

So it would be kindley, if somebody can help me here.

Thanks

Kind regards
