Hello HF. I found this tool awhile back. On Github I beleive. It has the ability to dump private keys from the following file types, XRP,BCH,BTC,LTC, ETC.. It really came in handy for me awile back when I lost my private key. It is very easy to use, with a simple layout and design. I will link a very short YT video below showing you guys what it looks so you get a general idea. Enjoy!
