YATD
Description
Yet another cipher to decode:
FH4E7LC@Ecf0243hbfh37_ge35fcN
Cipher Searcher
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
Flag
uwctf{rot47_acb9379bf086bd74}
