Part V — Applied cryptography at Koder
The payoff: every Koder Stack engineering decision tied to the right primitive. From identity to transport, from data to keys, to the discipline that keeps it all correct and ready for the post-quantum future.
| # | Section | What it covers |
|---|---|---|
| 1 | Identity and transport | Koder ID (Ed25519, Argon2id, passkeys), TLS 1.3 in Jet (AEAD + hybrid PQC + ACME), post-Terrapin SSH. |
| 2 | Data and keys | kzip (AEAD + recipient mode), key lifecycle (HSM, HKDF, rotation, Shamir), CSPRNG, multi-tenant. |
| 3 | Discipline and posture | koder_kit (misuse-resistant API), self-hosted + multi-tenant, crypto-agility, the complete picture. |
