🔍 Algorithm Comparison
| Algorithm | Output Length | Security | Use Case |
|---|---|---|---|
| MD5 | 32 hex chars (128-bit) | Broken — do not use | Legacy checksums, non-security use |
| SHA-1 | 40 hex chars (160-bit) | Deprecated — avoid | Git commit IDs, legacy systems |
| SHA-256 | 64 hex chars (256-bit) | Secure ✅ | File integrity, certificates, blockchain |
| SHA-384 | 96 hex chars (384-bit) | Secure ✅ | High-security applications |
| SHA-512 | 128 hex chars (512-bit) | Secure ✅ | Password hashing (with salt), digital signatures |
💡 Common Uses
File Integrity
Verify downloads haven't been tampered with by comparing hashes.
Password Storage
Store SHA-256+salt hashes instead of plaintext passwords.
Blockchain
SHA-256 is the backbone of Bitcoin mining and transaction verification.
Git Commits
Git uses SHA-1 (migrating to SHA-256) to identify commits uniquely.
Digital Signatures
SSL certificates and code signing use SHA-256 for authenticity.
Deduplication
Detect duplicate files or database entries by comparing hash values.
❓ FAQ
Is my data secure? Do you store my input?
No. All hashing happens in memory on our server and is never stored, logged, or shared. Your input text is discarded immediately after the hash is computed.
Which algorithm should I use?
SHA-256 is the recommended default for most applications. Avoid MD5 and SHA-1 for security purposes — they are cryptographically broken.
Can I hash files?
This tool hashes text input. To hash files, use command-line tools: sha256sum file.txt (Linux), shasum -a 256 file.txt (macOS), or CertUtil -hashfile file.txt SHA256 (Windows).
Why do I get the same hash for the same input?
That's the fundamental property of hash functions: deterministic — same input always produces the same output. This is what makes them useful for verification.
Is this tool really free? No catch?
Yes! All 50+ tools on Korpo.Pro are free with no ads, no signup, and no data collection. We offer optional paid tools (Pro API, PDF reports) if you need advanced features — but the hash generator is completely free, forever.
