This is a proof-of-concept project, implemented in Rust WebAssembly.
- Open qrtransfer.westxu.com on one of your device, select file, wait for it to be processed.
- Open qrtransfer.westxu.com on your another device, scan using the camera until finishing scanning all the qrcodes, and then save the reassembled file.
Sender:
- Read the file into binary data
- Compress it
- Hash it
- Split it into a lot of chunks
- Encode each chunk into a small qrcode
- Play them one by one
Receiver:
- Scan all the qrcodes
- Reassemble the chunks into one
- Validate the hash
- Decompress
- Save the file
The website is static, hosted on github pages, and auto-deployed by github actions. The file will be processed natively in your browser and won't be uploaded to any server. Try turn off your wifi before selecting the file.
Check release.
