Hash Generator

Generate MD5, SHA-1, SHA-256, and SHA-512 hashes for text and files

Hash Algorithms

MD5

128-bit hash (32 hex chars) - Fast but not cryptographically secure

⚠️ Not recommended for security

SHA-1

160-bit hash (40 hex chars) - Deprecated for security

⚠️ Not recommended for security

SHA-256

256-bit hash (64 hex chars) - Secure and widely used

✅ Cryptographically secure

SHA-512

512-bit hash (128 hex chars) - Maximum security

✅ Cryptographically secure

Security Recommendations

  • • Use SHA-256 or SHA-512 for security-critical applications
  • • Avoid MD5 and SHA-1 for password hashing or digital signatures
  • • Add salt when hashing passwords
  • • Consider using bcrypt, scrypt, or Argon2 for password hashing
  • • Hash functions are one-way - they cannot be reversed

Common Use Cases

  • • File integrity: Verify downloads haven't been corrupted
  • • Data deduplication: Identify duplicate files or content
  • • Digital signatures: Create unique fingerprints for data
  • • Cache keys: Generate unique identifiers for caching
  • • Database indexing: Create efficient lookup keys

How to use:

  • • Select one or more hash algorithms by clicking the checkboxes
  • • Enter your text in the input area or upload a file
  • • Hashes will be generated automatically as you type
  • • Copy individual hashes or all hashes at once
  • • Use SHA-256 or SHA-512 for security-sensitive applications
  • • MD5 and SHA-1 are provided for compatibility but not recommended for security
