Hash Function Best Practices
- • SHA-256: Best choice for most security applications and data integrity
- • SHA-512: Use for high-security applications or when handling large data
- • MD5: Fast but broken - use only for checksums, not passwords or security
- • File Verification: Compare hashes to detect file corruption or tampering
- • Encoding: Hex is most common, Base64 is more compact for storage
Type your text and every algorithm runs at once — no selecting one before you start
All the algorithm outputs appear together as you type, so you can compare MD5, SHA-1, SHA-256, SHA-512, and the rest side by side without switching modes. This is useful when you're looking at a hash value you found somewhere and aren't sure which algorithm produced it — you can check the length (MD5 is 32 hex chars, SHA-1 is 40, SHA-256 is 64, SHA-512 is 128) and then compare against your input to confirm. Uppercase and lowercase hex output are both available; some systems are case-sensitive about which they accept. The copy button on each row picks up just that line.
MD5 is fine for checksums, not for passwords
MD5 still shows up constantly in download verification and build artifact checks. That's a reasonable use — you're not trying to keep the data secret, just confirm it wasn't corrupted in transit. Where MD5 is actually dangerous is password storage, which some older systems still do. MD5 hashes billions of passwords per second on commodity hardware. SHA-256 is faster than bcrypt but far better than MD5 for general integrity use. For anything where you need to verify that text hasn't been changed and you also control both ends, SHA-256 is the right default. SHA-512 is worth considering if you're hashing large files and want the slightly larger output as extra margin.
