💖 SAFEXCEL(4) 💖

okay bestie, gather round, because today we're talking about safexcel — the Inside Secure SafeXcel-IP-97 security packet engine driver, and she is that girl. this is a section 4 kernel interfaces manual page, so buckle up 🎀

✨ NAME ✨

safexcel — Inside Secure SafeXcel-IP-97 security packet engine 👑

✨ SYNOPSIS ✨

so like, there's two ways to get her into your life, and it's giving pick your fighter 🦋

🧚 option one: bake her right into the kernel

to compile this driver into the kernel, you drop these lines into your kernel configuration file, no cap:

device crypto
device cryptodev
device safexcel

🧚 option two: module girlie

alternatively, to load the driver as a module at boot time, you put this line in loader.conf(5) and let her arrive fashionably late:

safexcel_load="YES"

✨ DESCRIPTION ✨

okay so the safexcel driver implements crypto(4) support for the cryptographic acceleration functions of the EIP-97 device found on some Marvell systems-on-chip. translation: hardware go brrr so your crypto doesn't have to 💅

the driver can accelerate the following AES modes:

• AES-CBC 🍓
• AES-CTR ✨
• AES-XTS 🦋
• AES-GCM 🌸
• AES-CCM 🎀

safexcel also implements SHA1 and SHA2 transforms, and can combine AES-CBC and AES-CTR with SHA1-HMAC and SHA2-HMAC for encrypt-then-authenticate operations. like, she does the encryption and the authentication, in that order, together. main character energy fr fr 🔥

• ipsec(4)
• random(4)
• geli(8)
• crypto(9)

✨ HISTORY ✨

the safexcel driver first appeared in FreeBSD 13.0. iconic debut, honestly 🌈

and that's the whole page bestie, we ate and left no crumbs 💖 this was the Debian build of the SAFEXCEL(4) manual, dated June 23, 2020 — mwah, love u, go encrypt something 🫶✨
