Unverifiedca-certificates is the package used in Linux distributions to manage trusted CA certificates, containing the root and intermediate certificates in the system trust store.69% similarUnverifiedShort-lived certificates are a type of cryptographic credential with an extremely short validity period, usually automatically issued and frequently rotated by an internal CA, with common validity periods ranging from a few minutes to a few hours.65% similarUnverifiedThe certificate chain consists of a root certificate (Root CA) → intermediate certificate (Sub-CA/Intermediate CA) → developer end-entity certificate forming a chain of trust, and if any node in the chain is invalid, the entire chain verification will fail.63% similarUnverifiedWith the spread of certificate transparency, short-lived certificates and automated rotation mechanisms, the certificate ecosystem's ability to respond to CA compromise is gradually improving, but the timeliness of disclosure and the reliability of revocation mechanisms remain areas that need continuous hardening.60% similar
