## GromWeb MD5 Center

**MD5 Center** is for **MD5 conversion and reverse lookup**. It can “Reverse a MD5 hash” and “Convert a string to a MD5 hash.”

MD5 (Message Digest algorithm, 5th version) is an algorithm which converts a given sequence of characters into another unique sequence of characters, with a fixed length, called “hash”. For instance, the MD5 hash of the word password is 5f4dcc3b5aa765d61d8327deb882cf99.

This website uses a MD5 reverse dictionary containing several millions of entries, which you can use with MD5 hashes from your application. Known MD5 sums: 832,927,522. This value should have exactly 32 characters.

MD5 hashes are theoretically impossible to reverse directly, ie, it is not possible to retrieve the original string from a given hash using only mathematical operations. Unfortunately, there is a way to decrypt a MD5 hash, using a dictionary populated with strings and their MD5 counterpart.

If some of the hashes you enter can be reversed, consider using another way of generating hashes, like using stronger algorithms (SHA-2, Whirlpool, etc), combining algorithms, and using a “salt”.
