📚 Hash Algorithm Information

Understanding different cryptographic hash functions

🔐 MD5 (Message Digest 5)

  • Output: 128-bit (32 hex characters)
  • Speed: Very Fast
  • Security: Broken - Not recommended for security
  • Use Cases: File integrity checks, non-security applications

🔒 SHA-1 (Secure Hash Algorithm 1)

  • Output: 160-bit (40 hex characters)
  • Speed: Fast
  • Security: Deprecated - Vulnerable to attacks
  • Use Cases: Legacy systems, Git commits

✅ SHA-256 (Secure Hash Algorithm 256)

  • Output: 256-bit (64 hex characters)
  • Speed: Moderate
  • Security: Secure - Currently recommended
  • Use Cases: Passwords, certificates, blockchain

🛡️ SHA-512 (Secure Hash Algorithm 512)

  • Output: 512-bit (128 hex characters)
  • Speed: Slower
  • Security: Very Secure
  • Use Cases: High-security applications

🎯 Common Use Cases

When and why to use hash functions

🔐 Password Security

  • Store password hashes, not passwords
  • Use SHA-256 or better with salt
  • Never use MD5 or SHA-1 for passwords
  • Consider bcrypt for production systems

📁 File Integrity

  • Verify file downloads and transfers
  • Detect file corruption or tampering
  • Create checksums for backups
  • Compare file versions

🌐 Web Development

  • Generate unique identifiers
  • Cache busting for static assets
  • API request signatures
  • Session tokens and CSRF protection

⚖️ Digital Forensics

  • Evidence integrity verification
  • Chain of custody documentation
  • Duplicate file detection
  • Data authenticity proof

❓ Frequently Asked Questions

For passwords: Use SHA-256 or SHA-512 with salt (better: bcrypt/scrypt). For file integrity: SHA-256 is standard and secure. For legacy compatibility: MD5 for non-security uses only. Avoid MD5 and SHA-1 for security-critical applications as they're cryptographically broken. SHA-256 offers the best balance of security and performance for most applications.

Generate a hash of your original file and store it securely. Later, hash the file again and compare results - identical hashes mean the file is unchanged. This detects corruption, tampering, or transmission errors. Use SHA-256 for security-sensitive files. Many software downloads provide SHA-256/MD5 checksums for verification.

You can hash files up to 100MB. Processing time depends on file size and algorithm: MD5 is fastest, SHA-512 is slowest. A 10MB file typically takes 1-3 seconds. Large files are processed in chunks to prevent browser freezing. For files over 100MB, consider using desktop tools or command-line utilities for better performance.

Never store plain hash passwords! Use proper password hashing functions like bcrypt, scrypt, or Argon2 which include salting and key stretching. Simple SHA-256 hashes are vulnerable to rainbow table attacks. If you must use SHA algorithms, always add a unique salt and use multiple iterations (PBKDF2). Our tool is for learning and non-critical applications only.

Both formats represent the same hash value - it's just display preference. Uppercase (A-F) and lowercase (a-f) hexadecimal produce identical results when compared. Most systems accept both formats. Choose based on your requirements: programming languages often use lowercase, while some security standards prefer uppercase. Our tool lets you toggle between both formats.
