Weak cryptography does not announce itself. It waits, until someone finds it.
Cryptographic systems are the silent foundation of everything your protocol does: key generation, signature corroboration, data encryption, randomness, and trust. When that foundation has flaws, no amount of application-layer security compensates for it. At Axiomscrypt, we review the cryptographic architecture of your system with the same rigor we apply to code, because in this domain, subtle is dangerous.
A cryptography audit is a deep methodological review of the cryptographic primitives, protocols, and implementations your system relies on. It examines not just whether you are using recognized standards, but whether you are using them correctly, in the right context, and without introducing weaknesses through implementation or design choices.
Majority of the cryptographic failures are not caused by broken algorithms. They are caused by correct algorithms used incorrectly: weak entropy sources, improper key derivation, flawed signature schemes, predictable randomness, or unsafe parameter selection. These mistakes do not surface in standard code reviews. They require a specialist eye.
Our AI-assisted analysis scans your codebase and architecture for cryptographic misconfigurations and known weak patterns before our expert reviewers step in. They then examine your system at the protocol level, assessing design decisions, implementation fidelity, and the real-world security of your cryptographic choices.
How keys are generated, stored, rotated, and derived. Weak entropy, improper derivation paths, and unsafe storage are among the exploited cryptographic weaknesses in production systems.
Review of digital signature implementations including ECDSA, EdDSA, BLS, and multi-signature constructions. We examine signing logic, corroboration flows, and common pitfalls such as signature malleability and nonce reuse.
Assessment of symmetric and asymmetric encryption usage: cipher selection, mode of operation, key size, IV handling, and padding schemes. Misconfigurations here can render encrypted data trivially recoverable.
On-chain and off-chain randomness is frequently misused. We assess how randomness is generated, sourced, and consumed, identifying predictability risks that can be exploited in lotteries, gaming, key generation, and commit-reveal schemes.
Review of ZK circuit design, constraint systems, and proof corroboration logic. Soundness failures and under-constrained circuits can allow invalid proofs to pass corroboration undetected.
Evaluation of hash function selection, collision resistance assumptions, and the integrity of commitment constructions used across your protocol.
Full documentation of reviewed components, methodology, all findings by severity, and overall cryptographic security posture.
Every issue rated Critical, High, Medium, Low, or Informational with precise methodological description, real-world impact, and remediation guidance.
Where weaknesses stem from architectural decisions rather than code, we provide clear guidance on stronger cryptographic design choices.
We review your fixes and confirm that resolutions are sound and complete before the final report is issued.
A signed summary suitable for sharing with partners, shareholders, or regulators.
We identify all cryptographic components in scope: libraries, custom implementations, protocols, and key management systems.
Our engine flags known cryptographic antipatterns and misconfigurations across your codebase.
Specialist auditors assess implementation correctness, protocol design, and the security of your cryptographic assumptions.
Where applicable, we construct test cases to validate vulnerabilities and confirm the impact of findings.
Complete findings report with a dedicated debrief with your auditing team.
We verify every fix. The final, accepted report is issued and ready to publish.
Cryptographic weaknesses are rarely visible until they are exploited. The time to find them is before your system goes live, not after.
The strongest encryption means nothing if the key was predictable from the start.
