Voltsig
Generate “visual signatures” of binary data that can be used to easily differentiate up to 67.4 bits.
Copyright 2021 Alistair Turnbull. Distributed under the MIT licence; see the
file LICENCE.
The signatures are generated in colour. The colours used are indistinguishable when rendered as greyscale, and the signatures are suitable for users with colour vision deficiency (aka colour blindness); however, viewing the images in colour gives an additional 9 bits of entropy.
Only the file voltsig.js is needed. It defines a single top-level
function:
voltsig(svgElement, s, options)— Replace the contents of the<svg>elementsvgElementwith an image that represents a hash ofs.
See voltsig.js for more detail.
