The complete story of designing a licensing and backup encryption system for a product shipped to customer sites. Ed25519 digital signatures, dual-envelope AES-256-GCM encryption, SHA-256 key derivation, and the master key trust trade-off.
Filesystem encryption, database TDE, column-level encryption, S3 server-side vs client-side - what each layer actually protects, the gaps between them, and how to choose. Drawn from real customer conversations.
A practitioner’s walkthrough of encryption fundamentals - symmetric, asymmetric, hashing - with real algorithm comparisons, a decision framework, and common mistakes from two decades of building production systems.
Most enterprises are buying the F-35s of software - full-scale platforms engineered for extreme scenarios they will never face. The future belongs to composable, modular architectures. A perspective on capability thinking vs platform thinking.
BitLocker encryption didn’t fail—trust boundaries shifted. When recovery keys are escrowed by default, control becomes conditional. Linux LUKS, VeraCrypt alternatives, and key management strategies for conscious trust decisions.
When geopolitics enters the infrastructure layer, convenience without control becomes fragile. Real incidents, technical alternatives, and why sovereignty requires deliberate architecture.
A real-world journey with HashiCorp Vault, HA Raft, and multi-cluster secret injection, built from production lessons, not lab demos.
A security audit exposed access control gaps in our SaaS GitLab. Here’s how we migrated to self-hosted GitLab, integrated with our corporate IDAM, and took control of our DevOps destiny.
