SHA-256 Hash Generator
Generate SHA-256, SHA-1, and MD5 cryptographic hashes from any text.
Generate the SHA-256 cryptographic hash of any text string instantly. SHA-256 is widely used for data integrity verification, password hashing, digital signatures, and blockchain technology. All processing happens in your browser — no data is sent to any server.
Features
SHA-256 Hash
Industry-standard 256-bit cryptographic hash function.
Text & File Hashing
Hash any text string or upload a file to get its SHA-256.
Client-Side Only
Hashing runs in your browser — your data never leaves.
Copy Hash
Copy the hex digest with one click.
How to Generate a SHA-256 Hash
- Type or paste text into the input field.
- The SHA-256 hash appears automatically.
- Copy the 64-character hex digest.
FAQ
Is SHA-256 reversible?▾
No — SHA-256 is a one-way function. You cannot recover the original input from the hash. This is by design for security.
What is SHA-256 used for?▾
Password storage (with salting), file integrity verification, digital signatures, blockchain transaction IDs, and HMAC authentication.
Hash Properties
- SHA-256 always produces a 256-bit (64 hex char) output.
- Even a 1-character change in input produces a completely different hash.
- SHA-256 is collision-resistant — no two inputs produce the same hash (in practice).
