# Private Cargo Registry | Secure Rust Crate Hosting | Cloudsmith

## Secure, private **Cargo** registry hosting for Rust teams

Cloudsmith gives your Rust teams a fully managed, private Cargo registry with enterprise-grade security, global distribution, and the policy controls to govern exactly what crates reach your builds.

## Create Your Private Cargo Crate Registry

Cargo is the package manager for Rust packages, known as Crates. Cargo helps manage dependencies and build Rust projects efficiently. Cloudsmith offers the world's first private, Cargo registry. If you use Rust, Cloudsmith is the place to store, control, and distribute all your Cargo Crates for your Rust projects.

Universal format support

## **One registry. Every format your teams need.** Cloudsmith centralises Cargo crates alongside every other artifact your software depends on.

- Use Cargo + 30 other software package formats
- Store compiled Rust binaries and raw assets alongside your crates
- Centralize dependency management across Rust, containers, and more in one platform

## How we support **Cargo**

Cloudsmith gives Rust teams a production-ready, fully managed Cargo registry that works with familiar tooling out of the box. No infrastructure to maintain, no limitations on scale.

[Read our Cargo documentation](https://docs.cloudsmith.com/formats/cargo-registry)

### Native Cargo registry support

Publish and install crates using standard cargo publish and cargo install commands. Cloudsmith is fully compatible with both sparse and Git-based registry protocols, including the high-performance sparse registry introduced in Cargo 1.68.

### Vulnerability scanning for Rust crates

Cloudsmith scans your Cargo crates for known CVEs and malicious packages, automatically flagging issues before they reach your builds. Set policies to block, quarantine, or alert based on severity.

### Governance policies and crate control

Create and enforce policies that govern which crates are permitted in your repositories. Block specific versions, require specific metadata fields, or quarantine crates that do not meet your criteria before any team member installs them.

### Global delivery via 600+ edge PoPs

Cloudsmith's CDN-backed infrastructure delivers your crates from the closest available edge node. Teams distributed across regions get fast, consistent pull speeds without any additional configuration.

### Entitlement token and OIDC authentication

Secure your private Cargo registry with entitlement tokens, API key authentication, or OIDC for CI/CD pipelines. Fine-grained access controls let you set per-team and per-repository permissions without sharing credentials.

## Why teams choose Cloudsmith for **Cargo**

Self-hosted registries and Git-based workarounds create operational drag. Cloudsmith removes the infrastructure burden and gives your Rust teams a registry that scales with them.

| Without Cloudsmith | With Cloudsmith |

| --- | --- |

| Teams fall back to Git repositories for private crates, losing proper versioning and dependency resolution. Dependency trees become fragile and hard to audit. | Cloudsmith gives you a standards-compliant Cargo registry with full semantic versioning, sparse protocol support, and fast dependency resolution that works exactly like crates.io for private code. |

| Self-hosted registry infrastructure demands ongoing maintenance, patching, and scaling work from platform teams who have higher-priority things to work on. | Cloudsmith is fully managed. There is nothing to install, patch, or scale. Your team configures a registry endpoint and ships crates - everything else is handled for you. |

| There is no visibility into which crate versions teams are pulling, no controls to block vulnerable or unapproved packages, and no audit trail when something goes wrong. | Every crate download and upload is logged. Vulnerability scanning flags CVEs automatically. Governance policies let you define exactly which crates and versions are allowed before they reach any build. |

## Signs you're ready to switch to Cloudsmith for **Cargo**

If your Rust teams are working around the limitations of Git-based registries, self-hosted tooling, or fragmented artifact stores, Cloudsmith is the upgrade your supply chain needs.

### Git repos standing in for a real registry

Using Git repositories as a Cargo registry workaround means you lose semantic versioning, structured dependency resolution, and the tooling compatibility teams expect. Cloudsmith gives you a proper registry from day one.

### Self-hosted infrastructure nobody wants to own

Standing up and maintaining a self-hosted Cargo registry requires storage backends, Git index management, and ongoing patching. Cloudsmith removes all of that so your platform team can focus on higher-value work.

### No controls on what crates reach your builds

Without governance policies, any crate version can reach any build. Cloudsmith lets you define which crates are permitted, block specific versions, and quarantine packages that fail security or quality checks.

### Crates isolated from the rest of your artifact pipeline

Managing Cargo crates in one tool, Docker images in another, and binaries in a third creates unnecessary complexity. Cloudsmith gives you a single platform for all 30+ formats your pipeline depends on.

### Slow dependency resolution hurting CI/CD speed

Git-based Cargo registries clone the entire index on every resolution, adding minutes to build times. Cloudsmith supports the sparse registry protocol, which only fetches the metadata your build actually needs.

## Frequently asked questions

### Does Cloudsmith support both sparse and Git-based Cargo registries?

Yes. Cloudsmith supports both the sparse registry protocol (recommended for Cargo 1.68 and above) and the older Git-based index protocol. The sparse protocol significantly reduces bandwidth usage and speeds up dependency resolution compared to cloning a full Git index.

### How do I authenticate with a private Cargo registry on Cloudsmith?

Cloudsmith supports entitlement token authentication and HTTP basic authentication for Cargo. You configure credentials in your .cargo/config.toml file. For CI/CD pipelines, OIDC-based authentication is available so you can avoid storing long-lived secrets.

### Can Cloudsmith scan my Cargo crates for vulnerabilities?

Yes. Cloudsmith performs vulnerability scanning on Rust crates, checking against known CVE databases. You can configure policies to automatically quarantine or block crates that exceed a defined severity threshold before they reach any developer or CI build.

### Can I enforce policies on which crates are allowed in my repositories?

Yes. Cloudsmith's policy engine lets you define governance rules for your Cargo repositories. You can block specific crate versions, require metadata fields to be present, or quarantine packages that do not meet your criteria - all before any team member installs them.

### Can I use Cloudsmith as an upstream proxy for crates.io?

Yes. You can configure Cloudsmith to proxy and cache crates from crates.io, giving your teams faster access to public crates while applying your own security and governance policies to everything that flows through. This also reduces your exposure to upstream outages.

### How does Cloudsmith compare to running a self-hosted Cargo registry?

Self-hosted registries require you to manage the Git index, storage backends, authentication, and ongoing patching. Cloudsmith is fully managed - you configure an endpoint and start pushing crates. There is no infrastructure to maintain and no scaling decisions to make.

### Can my Cargo repository store other package formats too?

Yes. Cloudsmith repositories support 30+ formats. You can store Cargo crates alongside Docker images, raw binaries, and packages from other language ecosystems in a single platform, giving your team one place to manage the entire software supply chain.

### How do teams in different regions get fast crate download speeds?

Cloudsmith delivers artifacts from 600+ edge PoPs worldwide. When a developer or CI runner pulls a crate, the request is served from the nearest available edge node. No additional configuration is required to get low-latency downloads across distributed teams.

### Does Cloudsmith provide audit logs for Cargo crate activity?

Yes. Every upload and download is captured in Cloudsmith's client and audit logs. You can see exactly which crate versions were pulled, by which users or CI tokens, and when. Logs can be exported to third-party observability tools for further analysis.

### How do I migrate existing private crates to Cloudsmith?

You can push existing .crate files to Cloudsmith using the Cloudsmith CLI or via the native cargo publish command pointed at your Cloudsmith registry. Setup instructions with pre-configured snippets for your organisation and repository are available directly in the Cloudsmith UI.
