MD5 & SHA Hash Generator

Generate secure cryptographic hashes for any text using MD5, SHA-1, SHA-256, SHA-384, and SHA-512 algorithms.

Enter any text to generate multiple hash values. No limits on length.

How to Use

  1. Type or paste text into the input field
  2. Click "Generate Hashes" to compute all hash values
  3. Copy individual hashes using the "Copy" button next to each algorithm
  4. Or click "Copy All" to copy all hashes at once
  5. Use these hashes for password storage, data verification, or file integrity checking

Security Note: All hashing happens in your browser. No data is transmitted to any server.

Use Cases

🔐
Password Hashing

Generate secure password hashes for storage

✓
File Integrity

Verify file contents haven't been modified

⛓️
Blockchain

SHA-256 is foundational to Bitcoin and many cryptosystems

🔍
Data Deduplication

Find duplicate files by comparing hash values

How It Works

  • MD5 (128-bit / 32 hex chars): Legacy algorithm - DO NOT use for security-critical applications. Vulnerable to collision attacks.
  • SHA-1 (160-bit / 40 hex chars): Deprecated - No longer recommended for digital signatures and certificates due to collision vulnerabilities.
  • SHA-256 (256-bit / 64 hex chars): Secure and widely used. Foundation of blockchain technology (Bitcoin). Recommended for most applications.
  • SHA-384 (384-bit / 96 hex chars): Stronger variant suitable for highly sensitive data. Used in some military and government applications.
  • SHA-512 (512-bit / 128 hex chars): Maximum security level. Produces the longest hash. Best for critical cryptographic operations.
  • One-Way Function: Hashing is irreversible - you cannot recover the original text from a hash value.
  • Deterministic: Same input always produces same hash output, making it ideal for verification.
