_AutoMD5 - Create and test MD5 hash from string

[Mechaflash]

_AutoMD5 allows you to input a string password and it outputs an md5 hash for you. It also allows you to test it via a pseudo GUI login.

At the end of the script, it outputs the MD5 encrypted string as well as the source code for a simple autoit login prompt in a txt file.

Notice in the source output, _Get_Stored_Encrytped_Password() is whatever method you use to store the original encrypted password. I.E. you create the encrypted password and store it in an INI file. Replace _Get_Stored_Encrypted_Password() with a function that's made to retireve it from the INI file.
