+CryptoServe is an open-source cryptographic platform with three layers:
+
+- **CLI** -- Scan codebases for weak crypto, generate CBOMs, enforce CI/CD gates, encrypt files. Zero dependencies, works offline.
+- **SDK** -- Python and Node.js libraries for encryption, hashing, signatures, JWT tokens, and key exchange. Context-aware algorithm selection with post-quantum support (ML-KEM, ML-DSA, SLH-DSA).
+- **Platform** -- Self-hosted server with centralized key management, automatic rotation, policy enforcement, FIPS 140-2/3 compliance, and audit logging.
