02Foundation · Cryptographic Enforcement
What Zero-Knowledge Architecture Actually Means
Every security guarantee is enforced by mathematics, not policy. The server stores only encrypted data — no filenames, no metadata, no content indicators, no key material.
Conventional Cloud Storage
Provider holds the keys
CryptoDrive Zero-Knowledge
Server holds only ciphertext

03Cryptographic Enforcement · Key Hierarchy
Four-Tier Key Model Limits the Blast Radius
The platform implements a four-tier key hierarchy designed to limit the cryptographic blast radius of any single key compromise. Each tier is independent — a compromise at one tier does not cascade to others.

04Data Flow · Zero-Knowledge Pipeline
Nine Steps From Plaintext to Opaque Storage
Every file traverses the same nine-step pipeline. The server never gains the cryptographic capability to decrypt — even if every other layer fails.
05The Seven Core Capabilities
What CryptoDrive Does
Every capability is built on the same foundation: client-side encryption, zero-knowledge persistence, and cryptographic enforcement of every guarantee.
06Sector Applications
Six Sectors. Same Architecture. Same Guarantee.
CryptoDrive's zero-knowledge architecture and cryptographic access controls are suitable for data protection requirements across multiple sectors. The encryption model does not change between deployments — only the access policies and integration patterns.
07Deployment Architecture
Four Models. Identical Encryption Guarantee.
All deployment models maintain the same zero-knowledge cryptographic guarantees — the encryption model is identical regardless of where the server infrastructure runs.
08Compliance & Certifications
Compliance by Architecture — Not by Policy
CryptoDrive's zero-knowledge architecture provides statutory and regulatory compliance by design. Because the platform operator cryptographically cannot access user data, CryptoDrive satisfies the most stringent data protection requirements at the architectural level.
Zero-knowledge encryption ensures ePHI is inaccessible to the platform operator. No BAA required for data content access (the platform cannot access ePHI). Cryptographic access controls enforce minimum necessary access.
Client-side encryption ensures the platform operator is not a data processor with access to personal data. Encryption keys controlled exclusively by the data subject. Data residency controls support Article 45 adequacy requirements.
Immutable encrypted audit logs with cryptographic verification. Zero-knowledge storage ensures financial records cannot be accessed by unauthorized parties. Cryptographic access controls support segregation of duties.
Personal information is de facto inaccessible to the business (platform operator) through zero-knowledge encryption. Consumer rights exercised through cryptographic access controls without platform mediation.
Client-side encryption ensures cardholder data is encrypted before transmission. The platform never possesses unencrypted PAN or sensitive authentication data.
Equivalent to GDPR compliance — zero-knowledge architecture eliminates platform operator access to personal data. Data residency controls available.

10Integration & Ecosystem · CryptoSuite Architecture
Five Protocol-Level Bindings Across the Suite
CryptoDrive is fully integrated into the CryptoSuite product ecosystem, sharing cryptographic foundations and zero-knowledge principles with every product. The integration is architectural — every product uses the same primitives.
CryptoBox
Hardware Root of Trust
Master encryption keys stored and managed in FIPS 140-3 Level 3 certified hardware security modules. Keys generated inside tamper-resistant hardware, used for cryptographic operations without ever leaving the HSM boundary. The CryptoBox serves as the cryptographic anchor for enterprise CryptoDrive deployments.
Explore integration →S3-SENTINEL
Zero-Trust Architecture
All CryptoDrive infrastructure operates under the S3-SENTINEL zero-trust security architecture with seven independent defense layers. Identity-aware access controls govern administrative access. Continuous behavioral monitoring detects and responds to anomalous access patterns. Automated threat containment isolates any detected compromise within seconds.
Explore integration →CryptoMail
Encrypted Attachments
Files sent as encrypted attachments through CryptoMail are stored in CryptoDrive and shared through cryptographic access controls. Recipients receive cryptographic pointers to the encrypted storage rather than the files themselves — eliminating attachment size limits and providing full zero-knowledge protection for all file-based communications.
Explore integration →Enterprise SSO
Identity Integration
Integration with identity management systems (SAML 2.0, OAuth 2.0, OpenID Connect, SCIM) for enterprise user authentication while maintaining zero-knowledge encryption. Identity providers handle authentication; CryptoDrive handles cryptographic authorization. User identities are mapped to cryptographic key pairs without exposing key material to the identity system.
Explore integration →REST API
Programmatic Integration
Programmatic access via RESTful API with client-side encryption SDK. Developers integrate CryptoDrive storage into custom applications while maintaining zero-knowledge guarantees. SDKs available for Python, JavaScript/TypeScript, Java, Go, and Rust. All encryption operations execute in the SDK — the API receives only encrypted data.

Source §17 — PAA-Optimized FAQ, all ten questions verbatim.
The cloud storage provider stores only encrypted data and cannot decrypt it. CryptoDrive implements this architecture where even CryptoMize cannot access user files. The encryption keys are generated, stored, and used exclusively on client devices -- never transmitted to the server.</p>
Even server-side encrypted services manage encryption keys on their servers. CryptoDrive's client-side encryption ensures encryption keys never reach our servers. The platform stores only encrypted blobs -- no filenames, no metadata, no content indicators -- and cryptographically lacks the ability to decrypt stored data.</p>
All encryption and decryption occurs on the client device through WebCrypto API (browser) or native cryptographic libraries (desktop/mobile). Optional CryptoBox HSM integration provides FIPS 140-3 Level 3 hardware-backed key management.</p>
CryptoDrive's zero-knowledge architecture makes it cryptographically impossible for CryptoMize to decrypt user files. The platform lacks the keys and the cryptographic capability. Legal demands for data produce only encrypted files that cannot be decrypted -- this is enforced through architectural design, not policy.</p>
You can set expiration dates enforced by cryptographic key destruction, revoke access at any time by rotating shared keys, and control exactly who can access each file. The server cannot grant or deny access -- it lacks the cryptographic capability.</p>
CRYSTALS-Kyber-768 and CRYSTALS-Dilithium3 were standardized by NIST in August 2024 specifically for this purpose. It matters for storage because adversaries can harvest encrypted data today and decrypt it once quantum computers become available. Post-quantum encryption ensures files stored today remain secure against future quantum decryption.</p>
All deployment options maintain identical zero-knowledge encryption guarantees.</p>
Every file version is independently encrypted with its own key. Deleted files are retained in encrypted form for a configurable retention period. Previous versions can be recovered with full cryptographic integrity verification.</p>
Optional CryptoBox HSM integration provides FIPS 140-3 Level 3 hardware-backed key management. All cryptographic primitives use NIST-standardized or NIST-recommended algorithms.</p>
