What is SHA-256?

SHA-256 is a cryptographic hash function that belongs to the SHA-2 family and produces a fixed-length 256-bit hash value (64 hexadecimal characters) from any input.

It is widely used in security applications, including password storage, file integrity verification, and digital signatures.

How to Use

  1. Enter the text you want to hash into the input field.
  2. Click the "Generate" button to calculate the SHA-256 hash value.
  3. Use the "Copy" button to copy the hash to the clipboard.

FAQ

What is SHA-256?

SHA-256 is a cryptographic hash function that belongs to the SHA-2 family. It generates a fixed-length 256-bit hash value (64 hexadecimal characters) from any input. It is widely used for password storage, data integrity verification, and other security-related purposes.

Can the original text be recovered from the hash value?

No. SHA-256 is a one-way hash function, and recovering the original text from the hash value is computationally infeasible.

Will the same input always produce the same hash value?

Yes. The same input always generates the same SHA-256 hash value. Even a one-character difference results in a completely different hash.

Is any data sent to the server?

No. All processing is performed locally in your browser using the Web Crypto API. Your input data is never transmitted to the server.
