# Sovereign Security: Why Local-first RSA Encryption with 0 Dependencies is the New Standard

### Introduction

Industry standards like Doppler and AWS Secrets Manager have revolutionized secret management, but they introduce two critical vulnerabilities for the modern engineer: **Cloud Dependency and Supply-Chain Bloat**

This is a security failure, since restricted SSH-only/Air-gapped sovereign environments cannot rely on an outbound connection to a third-party cloud. If they did, it is not just a latency issue -- it's a security failure.

And even if you use an SSH-only RSA encryption solution, it has dependencies. Each dependency is a backdoor to a vulnerability. This leads to **Supply-Chain Attacks** with runtime dependencies.

### The Solution

Cortlet has made a solution to fix this, called: `@cortlet-org/env-vault`

`@cortlet-org/env-vault` is an SSH-only, local RSA encryption vault. No cloud dependency, only local, no-network solution.

It has low-friction installation + setup steps, making it easy to use and easy to get started. The tool is also air-gapped and offline-first, making it a good solution for restricted SSH-only/Air-gapped environments.

### Comparison

| Metric | Traditional Secret Managers | @cortlet-org/env-vault |
| --- | --- | --- |
| Connectivity | Requires persistent WAN | Air-gapped / Offline-first |
| Dependencies | Dozens of packages, used at runtime | Zero packages, only few for the CLI. |
| Security Model | Shared Responsibility (Cloud) | Sovereign (Local Keys) |
| Architecture | Cloud-sync / SaaS | Local RSA Vault |

### Under the Hood

To maintain performance parity without sacrificing security, this tool leverages native system-level RSA Handshakes. Unlike traditional secret managers which use heavy runtime libraries, ours is built for:

*   Atomic Performance: We don't use runtime libraries. We use built-in NodeJS modules.
    

By maintaining zero runtime dependencies, we eliminate the primary vector for NodeJS supply chain attacks.

### Conclusion

The industry's move toward centralized cloud secrets was a compromise for convenience that cost us our security autonomy. For engineers operating in restricted sovereign environments, SSH-only, or air-gapped environments, that compromise is no longer acceptable.

`@cortlet-org/env-vault` is more than a tool; it is a return to a "Local-First" engineering standard. Secure your environment today without the cloud-sync tax.
