The ultra-compact, cryptographic data transport & identity layer
DTL (Domain Transport Language) combines ultra-compact serialization, cryptographic security, and Web3 integration for AI systems, critical infrastructure, and decentralized identity. DTLAuth replaces JWT, SAML, and OIDC with deterministic, cryptographically sealed tokens.

Core Features
Built for the modern era of AI, Web3, and critical infrastructure
Schema-First Design
Every table declares its schema inline. Self-describing, strongly typed, and deterministic validation without ambiguity or parsing tricks.
Learn more →Cryptographically Sealed
BLAKE3 hashing, Ed25519/secp256k1 signatures, and row-chain integrity built-in. One bit changes? Verification fails instantly.
Learn more →Web3-Native Architecture
Wallet-bound signatures, chain anchoring, and verifiable file hashes. Perfect for decentralized identity and blockchain integration.
Learn more →Ultra-Compact Serialization
Line-based format with minimal overhead. Typically 40-60% smaller than JSON or SAML equivalents, ideal for bandwidth-constrained systems.
Learn more →No Ambiguity Attacks
Unlike XML/SAML, DTL has a single canonical form. No namespace tricks, no whitespace exploits, no alg=none vulnerabilities.
Learn more →Easy Integration
Simple to parse in any language. Python SDK, TypeScript SDK, Go SDK, CLI tool, and FastAPI gateway included. Zero vulnerable dependencies.

Replace JWT, SAML, and OIDC with deterministic, cryptographically sealed tokens
ID Tokens (dtID)
User identity information, roles, audiences, and metadata encoded as pure DTL. Deterministic, hashed, signed, and verifiable.
Learn more →Access Tokens (dtAC)
Scope and resource-based permissions for APIs, gateways, and microservices. Run across clouds, blockchains, and edge networks.
Learn more →DTLAuth Gateway
Reference FastAPI microservice for token issuance, verification, and federation. Drop-in replacement for Keycloak, Auth0, or Okta.
