LibHaLo Demo

Simple message signing (C1 compatible mode)

(Mobile only) Generate an EIP 191 compliant signature of the provided message data. The message will be hashed using Keccak algorithm on the client-side (with the appropriate prefixes) and then the digest will be transmitted to the NFC tag for the actual asymmetric signing.

This demo is dedicated for earlier batches of tags. Please use it only if simple.html doesn't work.
