Hello David,
Your private key is stored in not encrypted form:
-----BEGIN PRIVATE KEY-----
....
-----END PRIVATE KEY-----
Thus, you just tick the 'Private key is in a separate file' checkbox and leave 'Password' field empty.
Use 'bbs-sailmt-p001.wprod.ds.aphp.fr.cer' for 'Certificate*' field
Use 'bbs-sailmt-p001.wprod.ds.aphp.fr.key' for 'Private key' field
At last,
This is a public forum...everyone can access that Private key (unencrypted) which you've just uploaded.
I recommend to regenerate....
