TSSSLSERVERCERTUPDATE(3ts)

💖 NAME 💖

TSSslServerCertUpdate — the Traffic Server TLS server cert glow-up function, bestie ✨

---

🎀 SYNOPSIS 🎀

#include <ts/ts.h>

TSReturnCode TSSslServerCertUpdate(const char *cert_path, const char *key_path)

---

🦋 DESCRIPTION 🦋

okay so TSSslServerCertUpdate() is the one that swaps in fresh server certs for the ones you already have configured in ssl_multicert.config. it figures out which mapping to touch by looking at the common name in cert_path — that's the vibe check it runs 🔍

and like, if you set key_path to nullptr? no stress, it'll just use cert_path for both the certificate and the private key. two-for-one, we love efficiency 💅

now the receipts: TSSslServerCertUpdate() returns TS_SUCCESS only when all three of these are true, no cap:

• there actually exists a mapping for that common name — if there's no match, bestie, it's not happening
• cert_path points at a valid cert
• the context gets updated to use that cert

all three or nothing. it's giving main character energy with trust issues, and honestly? fair 🫶
