Device encryption requirements were relaxed in Windows 11 24H2, with the Modern Standby or HSTI compliance no longer required and the DMA interfaces blocklist removed. [26] In September 2019 a new update was released (KB4516071 [27]) changing the default setting for BitLocker when encrypting a self-encrypting drive. Now, the default is to use ...

Perform encryption or decryption for eight 128-bit AES blocks at once ...
IronKey Uses AES 128-bit and 256-bit CBC-mode hardware encryption; KeePass Password Safe; LastPass [7] Linux kernel's Crypto API, now exposed to userspace; NetLib Encryptionizer supports AES 128/256 in CBC, ECB and CTR modes for file and folder encryption on the Windows platform. Pidgin (software), has a plugin that allows for AES Encryption
An AES instruction set includes instructions for key expansion, encryption, and decryption using various key sizes (128-bit, 192-bit, and 256-bit). The instruction set is often implemented as a set of instructions that can perform a single round of AES along with a special version for the last round which has a slightly different method.
This new attack, by Alex Biryukov, Orr Dunkelman, Nathan Keller, Dmitry Khovratovich, and Adi Shamir, is against AES-256 that uses only two related keys and 2 39 time to recover the complete 256-bit key of a 9-round version, or 2 45 time for a 10-round version with a stronger type of related subkey attack, or 2 70 time for an 11-round version ...
The Encrypting File System (EFS) on Microsoft Windows is a feature introduced in version 3.0 of NTFS [1] that provides filesystem-level encryption.The technology enables files to be transparently encrypted to protect confidential data from attackers with physical access to the computer.
Option to enable/disable support for the TRIM command for both system and non-system drives was added in version 1.22. [15] Erasing the system encryption keys from RAM during shutdown/reboot helps mitigate some cold boot attacks, added in version 1.24. [15] RAM encryption for keys and passwords on 64-bit systems was added in version 1.24. [15]
Key management takes place within the hard disk controller and encryption keys are 128 or 256 bit Advanced Encryption Standard (AES) keys. Authentication on power up of the drive must still take place within the CPU via either a software pre-boot authentication environment (i.e., with a software-based full disk encryption component - hybrid ...
