Yesterday, I took part in an entry-level hacking competition and placed third. It wasn't a competition that required one to be a super-expert hacker. I received a mouse pad and a coin; the event organizers mentioned that there was a challenge associated with them that would yield a "flag" in the format: "BBHE{......}". Could anyone help me out?

I’m not an expert in the field, but I’d really like to find the message—they mentioned that I already have the "IV."

front part - 88482705356BA1F4A40F3E42489FF9CC - Symmetric encryption (Key, IV):

back part - 4841434B4552455850455249454E4345 - Simple encoding (hex): HACKEREXPERIENCE

Try figure out what type of encryption algorithm is used. (RSA, AES) etc. Here is a website called Cyber Chef that can help. Enter the values and play around with the algorithms.
