    Do you mean to ask how to check a md5 checksum of a file?

    md5sum filename

    If you don't have md5sum installed then you need to sudo apt-get install coreutils first.

    Otherwise, not sure what you mean here.

    You can't.

    You can compute the MD5 hash of a file to see if it matches that one, but you can't recover a file from its MD5 hash.

    The best you can do is brute force it. (Actually that's not exactly true, but if you have to ask this question my guess is you won't be cryptanalyzing it.)

    I bet you are trying something malicious to crack the userpassword.

    Just a hint:use rainbow table.

    Password = vvv

    You know it might not really add to security if you help someone to crack a password. You should point him in the right directions at most in my opinion.

    I thought linux passwords were hashed with SHA256 and salted. I don't see how rainbow tables would help with that - or maybe I'm wrong. Based on the question and level of knowledge the OP doesn't appear to be trying to do this anyway. This thread has gotten way off track.

    FYI it has nothing to do with linux passwords.The md5sum is found through SQL injection in the web application where you can found the username and password in md5sum.

    And you are "social responsibility," for contributing to every suspicious question and activity.

    That said, I sincerely wish the OP good luck if they're conducting legitimate activity.
