One final question, can you (please) suggest what format the internal crypto support ?
Then I will see if I can convert it / or generate the suitable private key to this purpose 

Once again thank you for your time !

The format itself is likely fine, but the internal crypto code does not yet support PBES2 which explains why this private key cannot be used.
