Yet another cipher to decode:
As implied by the challenge description, we are given a cipher to decrypt
Considering the length, there is a good chance this string directly maps to a flag in some way, so let's try comparing the first 5 characters FH4E7 with uwctf
F: 70 -> u: 117
H: 72 -> w: 119
4: 52 -> c: 99
E: 69 -> t: 116
7: 55 -> f: 102
We can see that each time there is an offset of 47 in the ASCII representations of the characters
This implies ROT47, where letters are "rotated" by 47
uwctf{rot47_acb9379bf086bd74}
