Cryptography

A hands-on TypeScript tutorial for proving which agent, model, prompt, and supervisor produced a code changeset — and detecting any later tampering. You build canonical changeset hashing, ed25519-signed attestations, and an append-only chained ledger you can verify offline, with zero runtime dependencies and zero API keys.

A practitioner's guide to migrating from classical to quantum-safe cryptography. Covers NIST PQC algorithms, crypto agility architecture, cryptographic asset inventory, hybrid transition strategies, and real-world migration case studies from Google, Cloudflare, and Signal.

AWS Nitro Enclaves provide hardware-isolated compute environments where sensitive data can be processed without exposure to the parent instance, the hypervisor, or even AWS operators. This guide covers the architecture, attestation model, KMS integration, production use cases, the broader confidential computing landscape including AMD SEV-SNP, Intel TDX, and NVIDIA GPU TEEs, and practical guidance for determining when enclave-based security justifies the development complexity.

Explore the emerging quantum networking landscape from quantum key distribution to entanglement-based networks. Deep analysis of current deployments, technical challenges, investment landscape, and the timeline to a functional quantum internet connecting distributed quantum computers.

Discover how quantum-safe cryptography protects against emerging quantum threats, offering insights into strategic implementation and real-world challenges.
