Production-proven Shamir’s Secret Sharing Capacitor Plugin now available for iOS, Android, and Web apps
MIAMI–(BUSINESS WIRE)–#Data—Vault12, Inc., the pioneer of crypto inheritance, today announced the open-source release of the Shamir Secret Sharing plugin for Capacitor, a new plugin for the Capacitor framework that enables app developers to add quantum-safe data storage for iOS, Android, and web applications using Shamir’s Secret Sharing.
The Shamir Secret Sharing plugin for Capacitor plugin brings information-theoretic security—protection based on mathematical impossibility rather than computational difficulty—directly into modern, cross-platform app stacks. By splitting sensitive data into multiple cryptographic shards, developers can eliminate single points of failure and build applications that remain secure even in a post-quantum world.
This plugin has already been battle-tested in production for a decade on almost a million iOS and Android devices, as a core component of Vault12 Guard, a mobile app that provides decentralized backup, and inheritance for crypto wallets and other sensitive data.
“Developers building self-custody and high-assurance apps need tools that won’t break the moment quantum computing becomes practical,” said Blake Commagere, co-founder and COO of Vault12. “With the Shamir Secret Sharing plugin for Capacitor, we’re making the same Shamir’s Secret Sharing engine that powers Vault12 Guard available to anyone building the next generation of secure, user-controlled applications.”
Shamir’s Secret Sharing (SSS), originally devised by Adi Shamir (the “S” in RSA), allows a secret to be mathematically split into multiple shares, with a configurable threshold required to reconstruct it. Individual shares reveal nothing about the underlying secret, ensuring that no single compromise exposes user data.
Capacitor is an open-source, cross-platform native runtime that lets developers build iOS, Android, and web apps from a single modern JavaScript/TypeScript codebase. It provides a consistent API and plugin system to bridge web frameworks (React, Vue, Angular, etc.) with native device capabilities such as secure storage, biometrics, and the filesystem.
Key features of the Shamir Secret Sharing plugin for Capacitor plugin include:
- Quantum-resistant security using Shamir’s Secret Sharing with information-theoretic guarantees
- Cross-platform support for iOS, Android, and Web via Capacitor
- Flexible storage options, including memory-based and filesystem-based operations
- Progress tracking for long-running operations and large files
- Robust recovery, supporting reconstruction of complete secrets or individual shards
- Production-proven reliability, already protecting high-value digital assets for Vault12 Guard users
Developers can access the source code, documentation, and implementation examples on GitHub and more information about potential uses can be found in this blog post.
