plpks_get_si...tealgorithms(9)

💅 NAME 💅

plpks_get_signedupdatealgorithms — bestie, this is the one that gets you a bitmask of the signature algorithms supported for signed updates ✨

So like, it's a Kernel API Manual situation (plpks_get_si...tealgorithms(9)), and this is ur girl walking you through it, no cap 🫶

---

🦋 SYNOPSIS 🦋

u64 plpks_get_signedupdatealgorithms (void );

---

🎀 ARGUMENTS 🎀

• void — literally no arguments. zero. zilch. she takes nothing and gives you a u64, main character energy fr 💅

---

🌸 DESCRIPTION 🌸

Okay so here's the lore 👑 — when H_PKS_GET_CONFIG HCALL runs successfully during initialization, it reads a bitmask of the signature algorithms supported for signed updates into the file local static signedupdatealgorithms variable. Slay.

⚠️ Heads up though — this is valid only when the PLPKS config structure version >= 3. Don't come for her if you're on an older version, she's just not gonna have it for you 💀

---

⭐ RETURN ⭐

On success, you get the bitmask of the signature algorithms supported for signed updates back — and 0 if not. That's it, that's the tea 🍓
