`Usage: wordmap.py <wordlist file> <word to hash>`
for example `python3 wordmap.py wordlists/corncob_lowercase.txt "example words"` would result in `serenading`
for example `python3 wordmap.py wordlists/corncob_lowercase.txt "example words"` would result in `serenading`
and to use the terminal colors, on *nix-like systems you can use `(i="example";python3 wordmap.py wordlists/term16color.txt "$i"|tr -d \\n;printf "%s\33[0m\n" "$i")`
it can also be imported, something like `python3 -c 'a="example";from wordmap import wordmap;wordmap("wordlists/term16color.txt",a);print(a+"\x1b[0m")'`
corncob lists included here are from [http://www.mieliestronk.com/wordlist.html](http://www.mieliestronk.com/wordlist.html)
the colors list is from wikipedia, more specifically re-parsed from [https://raw.githubusercontent.com/codebrainz/color-names/master/output/colors.conf](https://raw.githubusercontent.com/codebrainz/color-names/master/output/colors.conf)

but you can use any newline-separated list of strings
