Cryptography audits that go beyond code review
De-risk ZK, MPC, FHE, and PQC changes with an audit that covers math, protocol, code, and hardware. We prioritize must-fix issues, map them to NIST/FIPS/ISO, and re-test – so partner approvals come faster and crypto-origin incidents post-release trend to zero.
Trusted by Web3 leaders, enterprises, and governments since 2017.

Your cryptography stack, verified end-to-end
What we verify
- Math: soundness of constraint systems; correct arithmetic and subgroup validation; algebraic/hybrid assumptions; collision‑resistance assumptions.
- Protocol: trusted/transparent setup correctness; constraint/gate integrity across circuits and zkVMs; execution trace correctness for zkVMs; recursive composition safety; batching security; resistance to proof forgery.
- Implementation: circuit and zkVM implementation correctness; proof generation efficiency; scalability characteristics; code integrity.
Outcomes you get
Proof integrity your partners trust → listings and bridge integrations proceed smoothly.
Reduced systemic risk from circuit or constraint-level design flaws.
What we verify
- Math: theoretical soundness.
- Protocol: QKD and QRNG protocol correctness, covering error-correction
- Implementation: implementation resilience; bias‑resistance validation.
- Hardware: entropy‑source validation.
Outcomes you get
Credible quantum posture for high-stakes systems.
Strong, testable randomness partners accept.
Simpler reviews with evidence on entropy quality.
What we verify
- Math: hardness assumptions and parameter correctness; post-quantum security of unforgeability, confidentiality, and zero-knowledge properties.
- Protocol: protocol soundness; constant‑time execution; side-channel resistance; interoperability with existing ecosystems.
- Implementation: compliance with FIPS requirements; code‑level execution checks; side‑channel resistance.
Outcomes you get
Standards-aligned PQC readiness that passes diligence.
Stronger security posture and resilience to implementation attacks.
What we verify
- Math: parameter choices and ciphertext noise growth.
- Protocol: integration into real‑world workflows; attestation flows; garbled‑circuit construction, key management, and oblivious transfer protocols.
- Implementation: correctness and efficiency; enclave isolation with resistance to side‑channel and rollback attacks, mitigation of common implementation pitfalls for garbled circuits.
- Hardware: hardware‑protected enclaves validated.
Outcomes you get
Attestation accepted by partners & auditors.
Privacy preserved without killing performance.
Fewer production escalations from rollback/side-channels.
What we verify
- Math: cryptographic proofs for multisignature/threshold schemes; common elliptic-curve pitfalls.
- Protocol: multisig/threshold‑scheme correctness and security assumptions; robustness against forgery and coordination errors; security of key-exchange protocols and hash functions.
- Implementation: best‑practice checks (nonce reuse, RNG quality, side‑channel leakage); real‑world execution checks for threshold signing; secure configuration and usage of core primitives (block ciphers, key exchange, hash functions); MAC key handling.
Outcomes you get
Alignment with current standards and resistance to known attacks.
Timing stability verified; nonce disasters avoided.
Faster sign-off for listings and enterprise deals.

Why teams choose cryptography audit by Hacken
Depth across layers
From theoretical soundness to implementation and practical adversaries protection: math → protocol → code → hardware, with real-world exploit paths and fix guidance.
Framework coverage
One audit for your full stack – ZK, ECC, MPC, FHE, PQC, etc. – so nothing falls between components.
Lower incident probability
Remove cryptography-origin failure modes before they reach production.
Standards alignment
Findings mapped to NIST/FIPS/ISO/CFRG so you can hand deliverables straight to diligence teams.
Actionable reporting & re-test
Prioritized fixes with owners/ETAs – followed by a re-test and dated certificate to close the loop.
Faster diligence
Give partners exactly what they need: standards-mapped findings (NIST/FIPS/ISO/CFRG) and a dated re-test certificate – no back-and-forth.
Cryptography code review and security analysis process
Scoping
Tailoring the scope to your cryptographic scheme and threat model.
Execution
Using a combination of formal methods, code review, and project-specific validation techniques, including but not limited to ZK constraint/circuit verification, constant-time & RNG testing, side-channel/timing probes, and TEE/HSM attestation checks.
Reporting and fixes
Actionable insights, risk assessments, and detailed recommendations.
Re-test
Validating applied fixes through focused reviews to ensure long-term robustness.
Tailoring the scope to your cryptographic scheme and threat model.
What you get after the audit
Prioritized findings
severity, exploitation path, and fix guidance.
Standards matrix
NIST/FIPS/ISO/CFRG mapping for every relevant finding.
Evidence pack
PoCs/traces, benchmarks, tests.
Re-test & certificate
remediation validation with dated attestation for your stakeholders.
Peace of mind
Must-fixes closed and re-tested, residual risks cataloged, go/no-go criteria documented.
