Hash functions turn any input into a fixed-size fingerprint. Developers use them for checksums, cache keys, file integrity, API signatures, and debugging — not for storing passwords (use bcrypt or Argon2 for that).
Supported algorithms
The VyomaStack Hash Generator computes:
| Algorithm | Output size | Common use |
| MD5 | 128 bits | Legacy checksums, non-security etag |
| SHA-1 | 160 bits | Git object IDs, legacy systems |
| SHA-256 | 256 bits | Modern checksums, blockchain, TLS |
| SHA-384 | 384 bits | High-security applications |
| SHA-512 | 512 bits | File integrity, strong fingerprints |
SHA-256 and SHA-512 are recommended for anything security-sensitive. MD5 and SHA-1 are fine for quick non-cryptographic checksums but are broken for collision resistance.
How to use it
1. Paste or type text into the input field 2. Select one or more algorithms 3. Hashes update as you type — instant feedback 4. Click Copy on any hash output
All hashing runs in your browser via the Web Crypto API. Your input never leaves your device.
Real-world use cases
- Verify file downloads — compare SHA-256 against the publisher's checksum
- Cache keys — hash long query strings for Redis/Memcached keys
- API debugging — reproduce HMAC or signature inputs step by step
- Database migrations — fingerprint config blobs before and after changes
- Git-style object IDs — SHA-1 of
blob <size>\0<content>
Hash vs encryption
| Hash | Encryption |
| One-way — cannot reverse | Two-way — decrypt with key |
| Fixed output size | Output size ≈ input size |
| Same input → same hash | Same input → different ciphertext (with IV) |
| Checksums, fingerprints | Confidentiality |
If you need to recover the original text, you need encryption — not hashing.
Never hash passwords with MD5/SHA
Password storage requires slow, salted algorithms:
- bcrypt, scrypt, Argon2 — designed to resist brute force
- Plain SHA-256 of a password is fast to crack with rainbow tables
Use the hash generator for data fingerprints, not credential storage.
Hash generator vs command line
bash echo -n "hello" | shasum -a 256 echo -n "hello" | md5
The browser tool is faster for quick checks while debugging — especially when you're already in VyomaStack for SQL, JSON, or JWT work.
