FAQ

What is a SHA-256 checksum?

A SHA-256 checksum is a 256-bit (32-byte) hash value generated by the SHA-256 cryptographic hash function. It is commonly used to verify data integrity and is part of many security protocols.

Is this tool free to use?

Yes, this SHA-256 checksum calculator is completely free and requires no registration.

Is my data secure?

Absolutely. All hashing is performed locally in your browser. Your text never leaves your device.

Can I use this for passwords?

While you can hash passwords, SHA-256 alone is not recommended for password storage. Use specialized password hashing algorithms like bcrypt or Argon2 for that purpose.
