I’m using for a school project the OPC UA Java SDK SampleConsoleClient and -Server. Everything worked well until some days ago, when I had to reinstall Eclipse.
Since then I cannot run the code which was running before.

When I start the code the first time, the Certificate should be created in the PKI/CA/private folder. Well the .der and as well the .pem files are being created, but the .pem file is empty and the following exception appears:

Exception in thread “main” org.bouncycastle.util.io.pem.PemGenerationException: encoding exception: exception using cipher – please check password and data.
