Hi, didnt know where to post this so came to my frequent board. I currently have a legacy application wrote in java and am trying to develop a new updated version of the application. The application relies on inputs from encrypted text files, the only thing is i dont know the type of encryption used in the old application. Is there any way i can go about determining the type of encryption and then brute forcing it? The company that developed the encryption package no longer exists so its obviously impossible to get anywhere that way?

[jibberish removed] Heres a preview to the encrypted code, the length of each file changes and the symbols/characters used also differ? Any suggestions are much appreciated.
