Note: this library is for a pure implementation of SSS in JavaScript; if you are looking for the API Library for SSSaaS, look here.
sssa.create(minimum, shares, raw) - creates a set of shares
sssa.combine(shares) - combines shares into secret
For more detailed documentation, check out docs/sssa.md.
To use in a browser, use either sssa.js with browserify or use the pre-built
sssa-min.js.
We welcome pull requests, issues, security advice on this library, or other contributions you feel are necessary. Feel free to open an issue to discuss any questions you have about this library.
To develop; npm install will install the necessary dependencies. After making
changes, please update the minified and testing bundles:
browserify ./sssa.js > sssa-base.js && uglifyjs --compress -- ./sssa-base.js > sssa-min.js && rm ./sssa-base.js && browserify ./test/sssa.js > ./test/all.js
The reference implementation for this cross-language project was written in Go, here.
Please make sure all tests pass before submitting a pull request. In particular,
node ./tests/sssa.js and loading tests/testing.html in available browsers
after rebuilding all.js with browserify via browserify ./tests/sssa.js > ./tests/all.js
will run all internal tests and the go-libtest suite's
tests should be run against the changes before submission.
