Хеш-инструмент — SHA-1/256/384/512

Вычисляйте хеши SHA-1, SHA-256, SHA-384 и SHA-512 любого текста. Полностью локально через WebCrypto браузера. Данные не покидают…

When you need to quickly hash a string — verify a checksum, generate an integrity fingerprint, derive a cache key — open the popup, paste, pick an algorithm, and read the hex. Hashing is done by the browser's native WebCrypto, the same primitive that backs HTTPS. Key features: - Four algorithms in one popup: SHA-1, SHA-256, SHA-384, SHA-512 - Live computation — the hex digest updates as you type - Character count for the input and hex-length count for the output, shown live - One-click copy on the full hex digest - Your last-used algorithm and UI language are remembered locally - Backed by `crypto.subtle.digest` — no third-party hashing library, no network No data leaves your device. The hash is computed on your machine; nothing is uploaded or logged.
