About File Hashing

File hashes are used to verify file integrity and authenticity. Common use cases include verifying downloads, detecting tampering, and ensuring data consistency.

  • MD5: Fast, but not secure for cryptographic use
  • SHA-1: More secure than MD5, but considered weak for security
  • SHA-256: Strong cryptographic hash, recommended for security-sensitive applications
  • SHA-384: Stronger than SHA-256, with a larger bit size
  • SHA-512: Even stronger, commonly used for secure file verification

All hashing is performed in your browser. No files are uploaded or stored.
