The MD5 hash of bff0cc42103de1b4721370e84dc24f635a7afeca41198c9b3e03946a1b6b7191d14356408a5e57ce6daf77e6e800c66fac7ab0482d57d48d23e6808e4b562daa is 6662e7201f0a30685cc4c52896919806

You can attempt to reverse the MD5 hash which was just generated, to reverse it into the originally provided string:

Reverse a MD5 hash

Feel free to experiment MD5 hashing with more strings. Just enter a new string and submit the form to convert it into another MD5 hash.

Convert a string to a MD5 hash

What is 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.

These hashes are mostly used to validate file integrity, to encrypt sensitive data (like passwords), and to generate unique identifiers.

Is it secure?

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.

Most web sites and applications store their user passwords into databases with MD5 encryption. This method appears to be safe as it seems impossible to retrieve original user passwords if, say, a hacker manages to have a look at the database content.

Unfortunately, there is a way to decrypt a MD5 hash, using a dictionary populated with strings and their MD5 counterpart. As most users use very simple passwords (like "123456", "password", "abc123", etc), MD5 dictionaries make them very easy to retrieve.

This website uses a MD5 reverse dictionary containing several millions of entries, which you can use with MD5 hashes from your application.

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".
