When to use this tool
Calculate SHA-256 from a hexadecimal byte representation. The hex reader reconstructs the payload and SHA2 computes its 256-bit digest.

Conventions and limitations
This hashes decoded bytes. Use the SHA2 tool to hash literal hexadecimal characters instead. Preserve leading zero bytes when copying a dump.
How to use this page

- Adjust tool options if needed, then choose Run tool.
- Copy the result or download the original output bytes.
Inputs and results are not added to the public catalogue or saved in the URL. Processing happens in your browser; HTTP Request and DNS over HTTPS send the requests you explicitly run. Files up to 128 MiB can be opened; decompression and image tools may have smaller processing limits. Large results have a shortened preview. Text and HTML downloads use UTF-8; binary downloads preserve output bytes. Pasted text follows browser newline handling; open a file when exact input bytes matter.
