As advances in quantum computing accelerate, so does the urgency to protect data that must remain confidential for years, even decades. Much of today’s encryption relies on mathematical problems that can be solved by future quantum computers, creating a “steal now, decrypt later” risk for sensitive information.
This week Vault12 Open source capacitor plugin that brings Quantum safe data storage For mobile developers. The plugin is built on: Sharing Shamir’s Secret (SSS) is a method of splitting a secret into mathematically independent pieces. This provides information-theoretic security, that is, protection based on mathematical certainty rather than computational difficulty.
MoveTheNeedle.news said: Blake ComagereThe co-founder and COO of Vault12 explains the company’s reasons for open sourcing its technology and the capabilities it brings to developers.
Open source as the foundation of security
For Vault12, open source is a core security principle, not a marketing position.
“The best way to ensure the best security and privacy solutions is to use an open source approach. This makes security transparent, has the advantage of allowing many experts to review and improve the code, and security flaws rarely survive this kind of scrutiny.”
Commagere points out that when dealing with sophisticated attackers, relying on the reputation of a proprietary vendor is not enough.
“In a world with serious malicious actors, the transparency and collaboration provided by open source is the best approach to achieving the highest level of security.”
The Company’s records reflect that view. The first component, a P2P relay jackwas open sourced in 2015. Vault12 has continued to contribute to open source and support independent developers ever since.
Why Capacitors?
Plugins are created for: capacitorIonic’s cross-platform framework that runs on iOS, Android, and the web.
“It provides a fast and efficient way to create mobile apps. So when we decided to open source Shamir’s secret-sharing quantum-safe approach, the Capacitor stack was the obvious way to proceed.”
This lowers the barrier for consumer and enterprise app builders by bringing quantum-resistant data protection to widely adopted mainstream development environments.
Use Cases: Inheritance, Collaboration, and Secure Storage
Vault12 has developed plugins to support a wide range of security workflows. Comagere highlights several scenarios:
family digital inheritance
“Parents can ensure that their digital assets are transferred seamlessly without exposing sensitive information throughout their lives.”
Several family members each share a secret. Only a threshold can reconstruct this.
Collaboration Certification
Teams can distribute access to critical systems to ensure no one person has full control. This reduces both the risk of external attacks and the risk of insider misuse.
gradual disclosure
Applications can only unlock information when required conditions are met, such as multi-party agreements or time-based triggers.
redundant backup
Encrypted shares can be stored on cloud providers, devices, or physical locations without providing complete information to a single provider.
The plugin works across iOS, Android, and web environments, so these workflows can work consistently across devices.
How Shamir’s Secret Sharing Differs from Other Approaches
Commagere makes a clear distinction between SSS and the common key storage methods used on mobile devices.
“There is no single key material stored anywhere. The secret is mathematically divided into pieces, and the pieces themselves do not reveal anything.”
This avoids inherent single points of failure, such as:
device keychain
secure enclave
cloud key storage
centralized server
He also briefly explains the differences from Multi-Party Computation/Threshold Signature Schemes (MPC/TSS).
“Compared to the MPC/TSS scheme, SSS is simpler and offline-friendly. It is better suited for long-term backup, recovery, and inheritance use cases.”
In the plugin:
Heavy computation runs natively on iOS and Android for performance reasons.
Large file operations do not block the UI and
JavaScript fallback supports web usage.
Production-level security and performance
The plugin uses the same SSS engine Vault 12 Guard This application has been in production since 2017.
“Used to protect sensitive secrets on many iOS and Android devices.”
Vault12 highlights several measures taken to ensure reliability.
Completely open source codebase
Automated Test Coverage
Base implementation for performance-critical tasks
Long-term cross-platform interoperability testing
Encourage public review and contributions
This positions the plugin as a production-ready component rather than an experimental library.
Performance Leading to Public Launch
The new modules are not new in this release. Vault12 has been doing this for almost a decade.
“We have been developing our Vault12 Guard product since 2015. Having been battle-tested in commercial environments, we believe it is an easy step to launch it to the wider community as concerns grow about using quantum computing to access encrypted data.”
This launch coincides with growing industry interest in quantum-proof methods for long-term data protection.
Future-proofing against quantum attacks
Many cryptographic schemes rely on the difficulty of factorization or discrete logarithms. Quantum algorithms threaten these assumptions.
“Quantum computers can solve problems like this in hours.”
Shamir’s secret sharing works differently.
“Security depends on mathematical impossibility, not computational difficulty.”
Using fewer shares than necessary makes it impossible for an attacker to reconstruct the secret. Because there are infinitely many mathematically valid solutions, partial information represents nothing. This is true whether attackers use existing systems or future quantum computers.
“Applications built today with the Shamir Secret Sharing plugin for Capacitor will remain secure no matter what computing revolution comes next.”
Who can use it?
The plugin is available to any developer using Capacitor. While Vault12 supports digital wallets, it also targets developers who:
Quantum-safe designs are often considered technical and difficult to implement. Vault12 aims to be accessible with standard components.
What’s next
The SSS plugin is part of a broader effort by Vault12.
“We are working to release more components as we discover new opportunities to protect your data.”
One of the future areas of focus will be security modules for: desktop applicationIt has historically lagged mobile and web environments in adopting modern encryption methods.
conclusion
Vault12’s open source Capacitor plugin represents a practical step toward developing quantum-safe applications. By making Shamir’s production-tested Secret Sharing implementation available to mobile and web developers, the company is expanding access to one of the few data protection technologies that resist current and future computing threats.
This release fits into Vault12’s long-running patterns. That means being committed to open source, building for real-world use cases, and preparing developers for a future where quantum-enabled adversaries are a realistic consideration. The building blocks for secure, distributed, and long-lasting data protection are now widely available, although the impact will depend on adoption.
