OP: XOR-CRYPTO
[ MATHEMATICAL OBFUSCATION ]
The XOR operation is symmetric. It is heavily used by modern malware to evade antivirus by obfuscating its text strings.
Objective: The following array is XOR-encrypted. The key is an integer equal to the number of letters in the word "flag".

bytes = [0x42, 0x48, 0x45, 0x43, 0x7f, 0x7c, 0x34, 0x76, 0x5b, 0x74, 0x73, 0x6a, 0x60, 0x79]
Hint: A simple FOR loop in Python will give you the answer.
