What is SHA-256?
SHA-256 is a SHA-2 family hash function that creates a 256-bit, 64-character hexadecimal digest.

How to generate a SHA-256 hash
- Enter the exact text you want to hash.
- The tool calculates the SHA-256 digest automatically.
- Copy the 64-character hash for your workflow.
- Compare a supplied hash in the verifier when checking a known value.
Common SHA-256 uses
Check file or message integrity, prepare data for a signing workflow, compare known values, and debug systems that exchange SHA-256 digests.
Hash comparison tips
- Compare the complete digest, including every character.
- Input changes such as whitespace or capitalization produce a different hash.
- Use a password-specific algorithm when storing credentials.
SHA-256 Hash Generator FAQ
What is SHA-256 used for?
It is widely used for integrity checks, signed data, certificate systems, software distribution, and blockchain-related workflows.
Can SHA-256 be reversed?
No. A cryptographic hash is designed to be one-way, so it cannot be decoded back into its original input.
Can SHA-256 store passwords?
Use a dedicated password-hashing algorithm such as bcrypt, Argon2, or scrypt instead. A fast general-purpose hash alone is not appropriate for password storage.
Does this tool upload my input?
No. The hash is calculated locally in your browser and your text is not uploaded or stored.
How long is a SHA-256 hash?
A SHA-256 digest is 256 bits and is normally displayed as 64 hexadecimal characters.
Why does one small change create a different hash?
Hash functions are designed so that even a one-character change produces a very different digest.
Can I hash a file with this tool?
This tool hashes the text you enter. For file verification, use a tool that reads the exact file bytes.
