SHA-256/512 Generator

Computes SHA-1, SHA-256, SHA-384, and SHA-512 hashes in parallel for the same input, using the browser's native Web Crypto (crypto.subtle.digest). It works in two modes: Text mode hashes typed input (UTF-8 encoded) live as you type, and File mode hashes an uploaded file's raw bytes via ArrayBuffer. All four digests are shown at once.

1. Pick the Text or File tab. 2. In Text mode, type or paste your text; all four hashes update instantly. 3. In File mode, click Select File and choose any file; its name appears and all four hashes are computed. 4. Use the Aa toggle to switch all hashes between lowercase and uppercase hex, and Clear to reset. Each hash panel has its own Copy button.

Four algorithms from the SHA-2 (and SHA-1) family are computed via crypto.subtle.digest: SHA-1 (160 bits, 40 hex chars, deprecated for security but still common for checksums), SHA-256 (256 bits, 64 hex chars), SHA-384 (384 bits, 96 hex chars), and SHA-512 (512 bits, 128 hex chars). Text input is UTF-8 encoded; file input is hashed as raw bytes. Case toggling only changes the displayed hex digits, not the underlying value.
