| D | inline-encryption.rst | 10 Inline encryption hardware sits logically between memory and the disk, and can
11 en/decrypt data as it goes in/out of the disk. Inline encryption hardware has a
12 fixed number of "keyslots" - slots into which encryption contexts (i.e. the
13 encryption key, encryption algorithm, data unit size) can be programmed by the
15 of a keyslot (and also a data unit number to act as an encryption tweak), and
16 the inline encryption hardware will en/decrypt the data in the request with the
17 encryption context programmed into that keyslot. This is very different from
18 full disk encryption solutions like self encrypting drives/TCG OPAL/ATA
19 Security standards, since with inline encryption, any block on disk could be
20 encrypted with any encryption context the kernel chooses.
