Hash Generator Tool

Easily generate hash values like SHA-256/SHA-1/MD5 from text. Useful for password verification, file checking, and tamper detection.

How to Use

  • Enter text, select an algorithm, and click the "Generate Hash" button.
  • The generated hash value can be copied with one click using the "Copy" button.
  • Use the clear button to reset input and results.

Notes

  • MD5 has low security, so SHA-256 is recommended for important uses.
  • Hash values cannot be reversed to original text (irreversible conversion).
  • Please be careful when handling personal or confidential information.

Tips & FAQ

  • What is a hash value?
    A fixed-length value calculated from original data. Used for tamper detection, password storage, file verification, etc.
  • What's the difference between SHA-256 and MD5?
    SHA-256 is safer and recommended. MD5 is fast but collisions have been found, making it unsuitable for important uses.
  • Can original data be determined from hash values?
    Basically irreversible. Be careful of brute force and dictionary attacks.
