Can you use US dollars in Algeria?

Excuse me, could you please clarify something for me? I'm a bit confused about the use of US dollars in Algeria. I understand that Algeria has its own currency, the Algerian dinar, but I've heard some people mentioning that they've been able to use US dollars there as well. Is it actually possible to use US dollars in Algeria, or is it more of a rumor? And if it is possible, are there any specific places or situations where it's more widely accepted? I'd really appreciate your insights on this matter.
