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
SHA-1
160-bit hash (40 hex chars) - Deprecated for security
SHA-256
256-bit hash (64 hex chars) - Secure and widely used
SHA-512
512-bit hash (128 hex chars) - Maximum security

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
