Frequently Asked Questions

Find Quick Answers

What is SHA256?

SHA256 (Secure Hash Algorithm 256-bit) is a cryptographic hash function that produces a 64-character hexadecimal string (256 bits). It's widely used for data integrity verification, digital signatures, and password hashing.

Is my data secure with this tool?

Yes, all SHA256 calculations happen entirely in your browser using JavaScript. No data is transmitted to any server, ensuring complete privacy and security.

What types of files can I hash?

You can upload any file type - documents, images, videos, archives, etc. The tool reads the file content and generates a SHA256 hash based on the binary data.

Can I use this for password hashing?

While SHA256 is a cryptographic hash, it's not recommended for password storage without additional security measures like salting and key stretching. Consider using dedicated password hashing algorithms like bcrypt or Argon2.
