Hash Generator
Utility Tools
Generate cryptographic hashes using MD5, SHA-1, SHA-256, SHA-384, and SHA-512 algorithms. Useful for data integrity checks and file verification.

Hash Algorithm Comparison
| Algorithm | Output Size | Security | Use Case |
|---|---|---|---|
| MD5 | 128 bits | Weak | Checksums only |
| SHA-1 | 160 bits | Deprecated | Legacy systems |
| SHA-256 | 256 bits | Strong | General purpose |
| SHA-384 | 384 bits | Strong | High security |
| SHA-512 | 512 bits | Strong | Maximum security |
Security Note: Hash functions are one-way functions. Never use MD5 or SHA-1 for security-sensitive applications like password storage. For passwords, use specialized algorithms like bcrypt, scrypt, or Argon2.
Multiple Algorithms
Generate hashes using MD5, SHA-1, SHA-256, SHA-384, and SHA-512 algorithms simultaneously.
Browser-Based
Uses the Web Crypto API for secure, client-side hashing. Your data never leaves your browser.
Instant Results
Get hash values instantly with easy copy-to-clipboard functionality for each algorithm.
Common Use Cases
File Integrity
Verify downloaded files match their published checksums to ensure they haven't been tampered with.
Data Deduplication
Identify duplicate content by comparing hash values instead of full content comparison.
Cache Busting
Generate content-based hashes for CSS/JS file names to ensure browsers load updated versions.
API Signatures
Create HMAC signatures for API requests to verify authenticity and prevent tampering.
Security Considerations
- ⚠️ MD5 and SHA-1 are considered cryptographically broken. Use only for checksums, not security.
- ✓ SHA-256 or higher is recommended for security-sensitive applications.
- ℹ️ For passwords, never use plain hashes. Use bcrypt, scrypt, or Argon2 instead.
