Free Online Password Hash Cracker Using Lookup Tables

What is CrackStation?

CrackStation is a free online tool designed to crack password hashes by leveraging extensive pre-computed lookup tables. Users can enter up to 20 non-salted password hashes and receive fast results for popular algorithms, including LM, NTLM, MD5, SHA1, SHA256, and more. By utilizing a database built from comprehensive wordlists and employing intelligent word mangling techniques, the tool greatly increases the chances of successfully recovering plaintext passwords from exposed hashes.

The hash values are swiftly searched within CrackStation's indexed lookup tables, making password recovery possible within seconds—provided the hash is included in the database. CrackStation's dictionaries are publicly available for download, enabling further security research and password testing. It is important to note this tool is designed for unsalted hash cracking and demonstrates the weaknesses of insecure password storing methods.
