Shamir secret sharing is an algorithm for splitting data into multipleshares, a subset of which can then be combined to reconstruct the original secret. This library aims to provide javascript bindings fordsprenkles/sss implementation of this algorithm using Web Assembly.
Currently there are bindings for sss in node.js. However this code will not run in the browser since it uses node binaries. By using Web Assembly it is possible to create a javascript library that works both in the browser as well as node.js.
// Import the sss libraryimport*assssfrom'sss-wasm'// Create a buffer for the data that will be shared (must be 64 bytes long)constdata=newUint8Array(64);data.fill(0x42);constamount=5;constthreshold=4;// Creating 5 shares (need 3 to restore)constshares=awaitsss.createShares(data,amount,threshold);// For demonstrational purpose, lose one of the sharesconstnewShares=[shares[3],shares[2],shares[4],shares[0]]// Restore the original secretconstrestored=awaitsss.combineShares(newShares);// Dump the original secret back to the screenconsole.log(restored)
We need Emscripten toolchain installed to build wasm.More info
You need to setup submodules first.
git submodules initgit submodules updatecd sssgit submodules initgit submodules updateThen go to the root folder.
