How to use?

[matthewhaywood]

Hi, javascript noob here and also very new to vernam ciphers!

I have a vernam ciphered text to test with. I assume this should be entered under 'Cryptext 1'? (In quotation marks?)
I also have an English dictionary file with 1 word per line that I have linked.

I'm a little unclear on what to enter for 'Cryptext 2'. Is it possible to input only a ciphertext and a dictionary file to bruteforce the one-time pad? Or is it only possible if you have the OTP already?

If it would be possible, could an example script be provided to show what's needed and exactly how everything should be entered?

Thanks for any assistance in advance!
