I need to make sure not to give false information, so the article should be speculative but based on logical connections between the keywords. Also, mention that if it's a personal file, contacting the source for the password would be the best approach. Maybe include techniques like checking online for similar puzzles, using cipher tools, or common password patterns where "hot" and "code postal" might be part. The conclusion should be that without more context, it's challenging but possible to explore various avenues.
