Where can I buy Tornado Cash?

Excuse me, could you please clarify where one might be able to purchase Tornado Cash? I've been hearing a lot about it recently and I'm quite interested in exploring its capabilities. I understand it's a cryptocurrency mixer, but I'm unsure of the most reputable and secure platforms to make such a transaction. Could you recommend any trusted exchanges or marketplaces where I can safely buy Tornado Cash tokens? Additionally, are there any specific precautions I should take to ensure my safety and security during the purchase process?
