SHA-256 Hash Generator
Generate a SHA-256 hash of any text in hex or Base64. Free and private: runs in your browser.
Type or paste text to get its 256-bit SHA-256 digest, updated as you type.
Hashing runs locally in your browser. Your input never leaves this page.
Use cases
- Verify a download or file checksum.
- Create test fixtures for authentication code.
- Debug a hash mismatch between two systems.
Frequently asked questions
Can a SHA-256 hash be reversed?
No. It is one-way. Short or common inputs can be guessed with lookup tables, which is why passwords need a slow, salted hash instead.
Is the SHA-256 Hash Generator free?
Yes. It is free with no sign-up, and it runs entirely in your browser, so your input is never uploaded or stored.
Is hashing the same as encryption?
No. A hash is one-way: you cannot get the input back. Encryption is reversible with a key. Use slow password hashes (bcrypt, Argon2, PBKDF2) for passwords and fast hashes (SHA-256) for integrity checks.
