I started with the text file from post #17 which is 1866 chars. I have not checked the ciphertext from post 1 because by the time I found this thread rogster001 had already posted the updated version.b = 1867 char long not the 1210 as first text file. you added more than just a 'd' ?
And please edit your post to add some line breaks to the cipher text, it's messing up the forum layout
