After reading many posts, I am still confused about the differences between these two.

Let me know if my understanding is correct:

MAC is encrypted string that is generated using a secret key and a message, and it's used to check no-repudiation.

HMAC is a MAC that is generated using a hash function and it's used to the check the integrity of the message.

Apart from the last bullet, this is a duplicate of What is the difference between MAC and HMAC? and in this form, this question is too broad. – kelalaka Sep 12 '19 at 12:02
Yes, I have already read that post before but I still don't know if my understanding is correct. – fox_haunter Sep 12 '19 at 12:46

Short answer: HMAC is a specific way of building a MAC, much like an apple is a specific kind of fruit. So none of your questions really makes sense: Does an apple taste better than a fruit? – yyyyyyy Sep 12 '19 at 13:59
if you read that post, which was extremely clear, and still do not understand, I dont think we can help – Richie Frame Sep 12 '19 at 13:59
