## Write up:
At the top of the python file you can see:
```python
# Hiding this really important number in an obscure piece of code is brilliant!
# AND it's encrypted!
# We want our biggest client to know his information is safe with us.
bezos_cc_secret = "A:4@r%uL`M-^M0c0AbcM-MFE055a4ce`eN"
# Reference alphabet
alphabet = "!\"#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ"+ \
"[\\]^_`abcdefghijklmnopqrstuvwxyz{|}~"
def decode_secret(secret):
"""ROT47 decode
NOTE: encode and decode are the same operation in the ROT cipher family.
"""
```
And then the file calls another function, to solve this I simply changed what function the program calls:
```python
decode_secret(bezos_cc_secret)
```
And this then produced:
```
picoCTF{1|\/|_4_p34|\|ut_dd2c4616}
```
