Choose a file to generate hash values (Max: 100MB)

All file types supported

Usage Guide

🎯 How to Use

  1. Select a file using the file input (Max: 100MB)
  2. Choose your preferred hash algorithm(s)
  3. Click "Generate Hashes" to create hash values
  4. Copy individual hashes or download all at once
  5. Use the hashes to verify file integrity or create unique identifiers

🔐 Hash Algorithms

  • MD5: Fast but less secure (128-bit). Good for checksums.
  • SHA-1: Better than MD5 but deprecated for security (160-bit).
  • SHA-256: Secure and widely used (256-bit). Recommended for most uses.
  • SHA-512: Very secure (512-bit). Good for high-security applications.
  • SHA-3: Latest standard, alternative to SHA-2 family.

💡 Use Cases

  • File Verification: Ensure files haven't been corrupted or tampered with
  • Duplicate Detection: Find identical files using their hash values
  • Digital Signatures: Create unique identifiers for documents
  • Password Storage: Store password hashes instead of plain text
  • Data Integrity: Verify data transmission and storage integrity

⚠️ Important Notes

  • This is a demo version with simplified hash algorithms
  • In production, use proper cryptographic libraries
  • MD5 and SHA-1 are considered insecure for cryptographic purposes
  • SHA-256 or higher is recommended for security applications
  • Hash values are one-way - you cannot reverse them to get the original data
