The cypher.py file asks you input, then it spits you out something like this:
[.+%([.+%([.+%(};,!][.+%([.+%(
[36.0, 101, 54.0, 54.0, 55.5, 16.0, 29.0, 41]
To convert it back to text, all you need is that array of numbers under the gibberish. Copy it and paste it into line two of decypher.py, then execute the file.
