Hash Function Comparison
| Algorithm | Output Size | Security | Use Case |
|---|---|---|---|
| MD5 | 128 bits | Broken | Legacy only, checksums |
| SHA-1 | 160 bits | Weak | Legacy systems |
| SHA-256 | 256 bits | Strong | Recommended for most uses |
| SHA-384 | 384 bits | Strong | Higher security needs |
| SHA-512 | 512 bits | Strong | Maximum security |
Common Uses:
- Data Integrity: Verify files haven't been tampered with
- Password Storage: Store hashed passwords (use bcrypt/argon2 for production)
- Digital Signatures: Create unique identifiers for data
- Checksums: Verify file downloads and transfers
- Blockchain: SHA-256 is used in Bitcoin and many cryptocurrencies
