Hi,

Thanks. From what I've been able to find online I've created a dictionary
file with words and the words I know the hash values to be and I'm trying
to get it to use that however when I run this I get no errors but it
doesn't do anything, like ask me to input my hash value. Am i just being
stupid?

  >  sys.exit(1)

>def dict_check():
  >  md5hashes = raw_input('\nPlease enter the Hash value to be decrypted:
')
  >  chklength(md5hashes)

>try:

>except(IOError):

>sys.exit(1)

>words = words.readlines()
>print "\n",len(words),"words loading…"
