- It is interoperable and compatible with B. Poettering's Linux
ssss-combine) from http://point-at-infinity.org/ssss/ so keys/shares can be created with one and recovered with the other. That project was used as the reference implementation for this project.
- It consists of a single
htmlfile which includes everything needed to split and combine a secret (no network connection needed). As a result it is fully usable from Windows, Mac OSX, Linux, and other operating systems with a modern browser.
There are some other implementations of Shamir's Secret Sharing Scheme (SSSS) floating around, but none seem to be compatible with each other. The Linux utility is great (which is why this project is compatible with it), but chances are the people you want to share the secret with are not running Linux.
The author of the Linux utility maintains a web page where the utility can be demo'd, but the author notes that it's not secure and should not be used for sensitive data.
The ssss.html file generated by this project has no server dependencies (or any other external dependencies) and is as secure as the browser or PC it's being used on. Additionally, it eliminates the need to rely on a 3rd party web site page that may or may not be available in the future.
