Frequently Asked Questions

Just type or paste your text into the input box. Hashes generate in real-time as you type — no button needed. All five algorithms (MD5, SHA-1, SHA-256, SHA-384, SHA-512) compute simultaneously.

Yes. File hashing runs in a dedicated Web Worker thread using the native Web Crypto API. The UI stays responsive even for multi-gigabyte files. There is no file size limit.

Drop your file, then click 'Verify Hash' and paste the expected checksum. The tool auto-detects which algorithm matches and shows a green checkmark if the hashes match, confirming file integrity.

MD5 produces a 128-bit hash and is fast but vulnerable to collisions — fine for checksums but not security. SHA-256 produces a 256-bit hash, is cryptographically secure, and is the standard for modern security (TLS, Bitcoin, code signing).

Yes. Click the 'Salt' button to reveal the salt input. The salt is appended to your text before hashing. This makes hashes resistant to rainbow table attacks and is standard practice for password hashing.

No. All hashing runs entirely in your browser using the Web Crypto API and Web Workers. Your text and files never leave your device.

Hash Generator — MD5, SHA-256, SHA-512 Online - Privacy-First, Offline Developer Tool

Global Architecture: This tool runs entirely in your browser using WebAssembly. Unlike server-side alternatives, your data (JWTs, Logs, SQL) never leaves this device. It works offline and handles massive files (1GB+) bounded only by your RAM.
