+Description
+Our data got corrupted on the way here. Luckily, nothing got replaced, but every block of 3 got scrambled around! The first word seems to be three letters long, maybe you can use that to recover the rest of the message.
+Download the corrupted message here.
+
+

+
+here's the content of message.txt
+
+```bash
+❯ cat message.txt
+heTfl g as iicpCTo{7F4NRP051N5_16_35P3X51N3_V6E5926A}4%
+```
+let's write a python solver.........
+
+---
+
+```python
+#!/usr/bin/python3
+
+with open("message.txt") as filp:
+	contents = filp.read()
+
+for i in range(0, len(contents), 3):
+	chunk = contents[i : i + 3]
+	a, b, c = chunk
+	print(c + a + b, end="")
+```
+---
+
+running the above script........
+
+```bash
+❯ python solve.py
+The flag is picoCTF{7R4N5P051N6_15_3XP3N51V3_56E6924A}
