raw_input("Please make sure you have SerializedSystemIni.dat inside the current directory, if yes press ENTER to continue.")

# Encryption service
encryptionService = SerializedSystemIni.getEncryptionService(".")
clearOrEncryptService = ClearOrEncryptedService(encryptionService)

# Take encrypt password from user
pwd = raw_input("Please enter encrypted password (Eg. {3DES}Bxt5E3...): ")

# Delete unnecessary escape characters
preppwd = pwd.replace("\\", "")

# Decrypt password
