If you give more information, such as what it printed into the console when you try to run decipher on a text file containing those hashes.
Without proper information I don't think I can help.
However running those md5 hashes thru hashcat I got this.

USERNAME:HASH:PASSWORD
root:e839b0ea1ed2522d630062a7ca7f4e7b:Arinol
Pizzardisti:a3087cddc095e0db3f67ec5b92e3d0e9:Ogang

This may not help with your problems using decipher, I don't own the game so I may not fully understand how this works.

copy paste below into codeeditor in game, build it, run the build then copy e839b0ea1ed2522d630062a7ca7f4e7b into enter passkey when it asks and press enter. you must have crypto.so in your "/lib" folder




print("Password Cracker")

cryptotools = include_lib("/lib/crypto.so")


password = user_input("Enter passkey to crack: ")

crackedpassword = cryptotools.decipher(password)
print(crackedpassword)
