SHA-256 Hash Generator

About the SHA-256 Hash Generator

SHA-256 Hash Generator computes the 256-bit digest from the SHA-2 family. It's the same hash used by Bitcoin, TLS certificates and Git commits — currently considered cryptographically secure.

How to use

1. Paste the text you want to hash.
2. Read the 64-character lower-case hex output.
3. Copy it with the clipboard button.

Benefits & key features

• 256-bit output is collision-resistant for all practical purposes.
• Matches sha256sum output byte-for-byte.
• Client-side WebCrypto implementation — no external calls.
• Good for Git-style content-addressable hashing in personal projects.

Pro tip

SHA-256 is fast and deterministic. For password storage you still want a slow KDF (bcrypt / Argon2) because attackers can hash billions of SHA-256s per second on a GPU.
