FAQ

  • Can all hashes be decoded?
    No! Hash functions (MD5, SHA-1, SHA-256) are one-way and cannot be reversed. This tool only works if the password is in our database of common passwords.
  • What passwords can be found?
    This tool can only find passwords that are in our database of common/weak passwords. Strong, unique passwords cannot be found.
  • What if the password isn't found?
    If the password isn't found, it means it's not in our database. The hash cannot be "decoded" - it can only be found if we have the original password in our database.
Disclaimer: Hash functions are one-way cryptographic functions. This tool can only find passwords that exist in our database of common passwords. It cannot "decode" or "decrypt" hashes - it only looks up if we already know the original password. Strong passwords will not be found. This tool is for educational and security testing purposes only.
