MD5 Can be Decrypted. Unbelievable!

[cancer10]

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:

8b1a9953c4611296a827abf8c47804d7 | Hello
c1a5298f939e87e8f962a5edfc206918 | Hi

Besides, that site can't decrypt anything.

You mean they maintain a full dictionary of all hashes?

[Nile]

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

[cancer10]

Works fine for me.

Does "8b1a9953c4611296a827abf8c47804d7" work for you?

[cancer10]

Nope!

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


BTW, is it impossible to break or reverse md5?

[Nile]

Not by machine, so what does work for you (md5 please).

Ah.. It does. Well, yeah. They just match up in the db.
