NVMe and ATA Sanitize Explained: Crypto Erase, Block Erase, Overwrite
Sanitize makes an SSD erase user data everywhere, spare blocks and caches included. How crypto erase, block erase and overwrite differ, with commands.
Deep dives, practical guides, and incident analyses from engineers who build Safeguard. No fluff, no vendor FUD — just what you need to ship secure software.

A lost device broadcasts a rotating public key over Bluetooth; strangers' phones encrypt their location to it, and only the owner holds the key to read it.
5G hides your SIM identity with SUCI and lets your home network confirm logins via 5G-AKA, only on standalone 5G. Your hotspot is still a small router.
Quantum error correction spreads one logical qubit over many noisy ones and fixes errors without reading the data. How surface codes and thresholds work.
PCIe 6.0 doubles to 64 GT/s with PAM4, fixed 256 byte FLITs, light FEC plus strong CRC, and IDE link encryption keyed over SPDM. Here is how each works.
Undersea cables carry light through fiber pairs, boosted every 70 km or so by repeaters powered with up to 18 kV fed from shore, and are fixed by ship.
USB PD starts with resistors on the CC wire, then Source_Capabilities, Request, Accept and PS_RDY. How EPR reaches 240 W and what authentication adds.
Back up PK, KEK, db and dbx, put firmware in Setup Mode, enrol your own keys with sbctl or efitools, then sign the kernel, UKI and modules safely on Linux.
Fiber starts as ultra pure glass soot built into a preform, is drawn to 125 microns, coated, proof tested, cabled, then laid, spliced and tested.
