PKCSSLOTD(8)

💖 PKCSSLOTD 💖

okay bestie, gather round, because we're talking about pkcsslotd — the shared memory manager for opencryptoki, section 8 of the manual (that's the "system administration / daemons" shelf, iykyk). 🎀

✨ NAME ✨

pkcsslotd — shared memory manager for opencryptoki 🧚

---

🌸 DESCRIPTION 🌸

So like, pkcsslotd is the daemon that manages PKCS#11 objects between PKCS#11-enabled applications. It's literally the group chat moderator for your crypto tokens. 👑

Here's the vibe: when 2 or more processes are accessing the same cryptographic token, the daemon gets notified, and then it updates each application when the token's objects change. Everyone stays in sync. No drama. No stale objects. Periodt. 💅

---

🦋 NOTES 🦋

okay so this part matters, bestie, don't scroll past it:

• Only one instance of the pkcsslotd daemon should be running on any given host. One. Singular. Not two. We are not doing that. 🫶
• If a prior instance of pkcsslotd did not shut down cleanly, then it may leave an allocated shared memory segment on the system. Messy of it, honestly. 💀
• That allocated memory segment can be identified by its key, and it can be safely removed once the daemon is stopped with the ipcrm command, such as:

ipcrm -M 0x6202AB38

⚠️ note the order pls: daemon stopped first, then ipcrm. Don't be out here removing segments while the thing is still running, that's not the move. 🙈

• The daemon creates the shared memory segment with group ownership by the pkcs11 group. 👑
• All non-root users that should be able to use openCryptoki need to be members of the group. Yes, all of them. Add them. 🌈
• Only trusted users should be assigned to the group. fr fr. See the "SECURITY NOTE" in the opencryptoki(7) manual page for details. 🧚
