i have a string i want to DECRYPT this hash string, i search online but no database can decrypt this? give me direction what should i do?You can't, that's the whole point. I can't think of any good reason why you'd want to do this anyway.There isn't any information "encrypted" in an MD5 has string. It's just a hex number. MD5 is not an encryption, but a hash. The difference between encryption and hash is that with an encryption algorithm it is a 2-way process encrypt<->decrypt. With a hash this is a 1-way process, there is no decryption possible.
MD5 hashes can not be "decrypted" but you can try to look them up in a rainbow table.

Here are some sites that support this:
http://tools.benramsey.com/md5/
http://gdataonline.com/seekhash.php
http://hashcrack.com/index.php
http://plain-text.info/

I saved plain-text.info for last because although it is defiantly the best, it may take it a long time to find you hash.

Its also important to note that depending upon the seer randomness of your original string none of these databases my have the hash.

Good luck!a Rainbow table only helps of the has itself is generated using something sort and easily indexable.

a rainbow table isn't going to help rebuild a file out of it's MD5 hash. It will only work on something that is often shorter and contains english words such as a password. We don't help crack passwords, which would be exactly what we would be doing if that is the case. Which I suspect it is.

of course since any self-respecting password hash has EITHER moved away from MD5 or is using MD5 with salts (which makes rainbow tables nearly useless) I doubt it's a password. Or if it is the OP isn't well-versed in the method used to create the hash. (this is implied given they seem UNAWARE of the one-way nature of a hash FUNCTION).

MD5 has string.

A "has string"?  ST with a typo?  What's this world coming to?
