Cosign Keyless Signing
Cosign Keyless Signing governs OIDC based signing, shaping system behavior under specific failure modes and workloads.
Definition
Cosign Keyless Signing is a design property concerning OIDC based signing. It defines how the system behaves under specific conditions — what guarantees hold, what trade-offs apply, and how the mechanism interacts with related techniques. The property is only meaningful when its preconditions are met; outside those conditions it provides no benefit and may add cost.
Context and scope
Apply Cosign Keyless Signing when designing systems where OIDC based signing matters. It is most useful under partial failure, high load, or correctness requirements. Pair it with observability to verify the claimed behavior in production. Do not assume the property holds without testing the specific configuration and workload.
Common misconceptions
- Cosign Keyless Signing eliminates all problems in its domain — it only bounds or shapes specific failure modes, not all pathologies.
- Cosign Keyless Signing is free once you adopt the right tool — the property depends on configuration, workload, and failure pattern, not the product label alone.
Anti-patterns
- Enabling Cosign Keyless Signing without measuring its cost in latency, availability, or operational complexity under production-like conditions.
- Assuming Cosign Keyless Signing composes safely with other guarantees — combining mechanisms can introduce new failure modes or negate benefits.
