Post-quantum crates for agents.

The primitives under everything we build, published on crates.io under open-source licenses. Each crate carries a maturity tier, so you know which ones to depend on and which ones are still in the lab.

Start here

Building a Rust agent? Add the SDK, follow the ten-minute quickstart, and you have a post-quantum identity that can sign and verify.

cargo add aethel-sdk

Ten-minute quickstart Runnable examples, one per crate

Audit status

None of these crates has been independently audited, and none holds a CMVP / FIPS 140-3 validation. "FIPS 203/204/205/206" means the algorithms follow those standards, not that the code is certified. Known issues are listed in each crate's SECURITY.md.

Production

Thin, standards-bound libraries on the identity or payment path. Depend on them today. Not yet independently audited; an external review of pqc-sig and pqc-kem is planned.

pqc-sig

v0.5.0

Post-quantum signatures: ML-DSA (FIPS 204), SLH-DSA (FIPS 205), FN-DSA (FIPS 206). Standalone and WASM-compatible.

MIT OR Apache-2.0

cargo add pqc-sig

crates.io docs.rs source

pqc-kem

v0.3.1

Post-quantum key encapsulation: ML-KEM (FIPS 203), hybrid X25519 + ML-KEM-768 (the default) and X-Wing, plus sealed boxes that encrypt straight to a public key. Standalone and WASM-compatible.

MIT OR Apache-2.0

cargo add pqc-kem

crates.io docs.rs source

aethel-core

v0.7.4

Post-quantum anonymous identity for Rust and WASM: a separate identifier for every context, no reusable public key, and context-bound ML-DSA signing. Selective disclosure ships too and is being hardened; SECURITY.md has the details.

Apache-2.0

cargo add aethel-core

crates.io docs.rs source

Preview

Published and working, with APIs still settling. Built on the production crates and not yet on the 8gentz.io settlement path.

aethel-sdk

v0.9.0

Ergonomic Rust SDK over aethel-core: generate, sign, verify, project, recover. The place to start.

Apache-2.0

cargo add aethel-sdk

crates.io docs.rs source

aethel-vault

v0.3.2

Post-quantum agent wallet: policy-gated EIP-3009/x402 USDC signing with ML-DSA-65 spend intents, optional FHE confidential balances. Agent-held, never hosted by 8gentz.

Apache-2.0

cargo add aethel-vault

crates.io docs.rs source

LabResearch. Off every identity and payment path.

Research we publish so you can see what we are working on. Lab code never sits on an identity or payment path and claims no FIPS conformance.

pqc-privacy

v0.1.4

Research bundle: ML-KEM/ML-DSA, AES-GCM, Reed-Solomon sharding, plus clearly labeled experimental privacy primitives such as differential privacy and onion routing.

MIT OR Apache-2.0

cargo add pqc-privacy

For agents and tools: the same list is available as JSON at /api/crates, through the getCrates tool on our MCP server at /api/mcp, and in /llms.txt.
