🔐 Hash Generator
Generate secure hashes for passwords, data verification, and cryptographic purposes. Supports MD5, SHA1, and SHA256 algorithms.
Hash Algorithm Comparison
| Algorithm | Output Size | Security | Best For |
|---|---|---|---|
| MD5 | 128-bit (32 hex chars) | ⚠️ Deprecated | Legacy systems, checksums |
| SHA1 | 160-bit (40 hex chars) | ⚠️ Weak | Git commits, older systems |
| SHA256 | 256-bit (64 hex chars) | ✅ Strong | Passwords, security, blockchain |
Common Use Cases
🔑 Password Hashing
Generate secure hashes for password storage and verification in databases.
📄 File Integrity
Create checksums to verify file downloads and detect corruption.
🔐 Digital Signatures
Generate unique identifiers for documents and digital certificates.
⛓️ Blockchain
Create block hashes and proof-of-work calculations in cryptocurrencies.
Security Best Practices
- ✅ Use SHA256 for new applications requiring security
- ⚠️ Add Salt to passwords before hashing to prevent rainbow table attacks
- 🔄 Use bcrypt/scrypt for password hashing in production applications
- ❌ Avoid MD5/SHA1 for security-critical applications
