SHA-256 Generator
Generate a secure SHA-256 hash from any text, instantly and privately.
How to use SHA-256 Generator
- Type or paste your text into the box.
- The 64-character SHA-256 hash appears instantly.
- Copy the hash to verify a file, store a fingerprint, or compare values.
- For password storage specifically, prefer bcrypt, which is designed to be slow.
What is SHA-256 Generator?
SHA-256 is a cryptographic hash function in the SHA-2 family that produces a 256-bit value, shown as 64 hexadecimal characters. It's one-way (you can't reverse it) and collision-resistant, which is why it underpins TLS, Bitcoin, and software-integrity verification.
Like all hashes, the same input always produces the same output, and any change produces a totally different hash. SHA-256 is the modern standard for checksums where security matters.
About the SHA-256 Generator
The SHA-256 Generator creates the SHA-256 hash of any text — a 64-character hexadecimal value from the SHA-2 family that's trusted across modern security: TLS certificates, blockchain, digital signatures and file-integrity verification.
Enter your text and the hash is computed instantly using your browser's built-in Web Crypto API, so nothing is sent anywhere. Use it to verify downloads, generate fingerprints, or build checksums that are far stronger than MD5.
It's free and unlimited. Unlike MD5, SHA-256 has no known practical collisions, making it suitable for integrity and security checks.
