The article mentions a code breaking software - any idea what that is? I have a coded letter that is about 250 years old, but it is written in Devanagari script so letter frequency isn't straightforward. Please do suggest any tools that can help in decoding.

Do you have a link to your codes letter available online?

I don't, but I can upload a sample tomorrow in case you're interested in taking a look.
