Wasalam, MD5 is a hashing Algorithm, you can't revert it (i.e get the original value) It's not an encryption. The easiest way to crack MD5 is to launch a dictionary attack, pick each word from your dictionary and convert it into an MD5 hash then compare it with your original hash. A match means you have a word in your dictionary that maps to your hash and is indeed your original string that you want.

PSEUDO CODE for your program:

Code:

hash_to_crack = textbox_value_here
for each word in the dictionary:
      hash = convert_word_to_md5_hash()
       if hash matches has_to_crack:
              display to the user that the cracked string is: word
              break the loop
       else keep on matching till the dictionary ends or a valid match is found
