SHA256 Generator

Converts any text you type into its SHA-256 digest — a 64-character hexadecimal string — computed entirely in your browser. It's the same underlying tool as the Hash Generator, just opened with SHA-256 selected by default instead of asking you to pick an algorithm first.

Type or paste the exact text you want to hash; the SHA-256 digest updates immediately as you type. Algorithm buttons for MD5, SHA-1, SHA-384, and SHA-512 are also shown if you need to switch, since this page uses the same component as the Hash Generator with a different default.

The UTF-8 text "hello", without quotation marks or a trailing newline, produces the SHA-256 digest 2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824. Capitalization, spaces, tabs, and line endings are all part of the input, so preserve them exactly when comparing against a hash from another source.

The tool encodes your text as UTF-8 bytes and passes them to the browser's native Web Crypto API (crypto.subtle.digest("SHA-256", …)), the same implementation web applications use for cryptographic hashing. Each byte of the 256-bit result is represented as two hexadecimal characters, producing the 64-character digest.

SHA-256 is part of the SHA-2 family and remains widely trusted for checksums, Git-adjacent contexts, TLS certificates, and Bitcoin's proof-of-work — unlike MD5 and SHA-1, it has no practical collision attacks as of this writing. That's why it's the default algorithm here and on the general-purpose Hash Generator.

This hashes exactly the text you type — it doesn't hash files directly, doesn't support keyed/HMAC hashing, and doesn't offer a text encoding other than UTF-8. A matching hash confirms two inputs are byte-identical; it doesn't verify who produced the input or protect a password by itself without a dedicated password-hashing function.

Hashing runs entirely in your browser using the Web Crypto API. The text you enter is never uploaded to a server.
