    Unhappy MD5 Can be Decrypted. Unbelievable!

    Hi Guys!

    Until yesterday I was under an impression that MD5 hashes cannot be reversed and is thus secured but then I found this site http://www.md5decryption.com/ which actually reverses your MD5 hash value, I was like WTF.

    I am sure there are other sites that can decrypt other hash functions like sha1, tiger160, sha256 etc.

    Please share your views about it?


    Thanks

    No, it just matches the words up. They have a database that has something like this:
    Code:

    c1a5298f939e87e8f962a5edfc206918 | Hi
    Besides, that site can't decrypt anything.

    You mean they maintain a full dictionary of all hashes?

    Yes they do. But does the decryption work for you? It doesn't for me.

    Nope!

    Wow! they actually maintain a db for all possible hashes....


    BTW, is it impossible to break or reverse md5?
