2020-06-20Windows: Fix issue when RAM encryption used, AES selected and AES-NI not ↵Mounir IDRASSI1-0/+5
supported by CPU that caused the free space of newly created volumes not filled with random data even if "quick format" is not selected by user.
2019-10-01Windows Driver: Disable Hibernation when RAM encryption is enabled since we ↵Mounir IDRASSI1-0/+6
can't resume from Hibernation without RAM encryption keys (a chicken and egg situation)
2019-02-28Windows driver: call VcProtectKeys only when RAM encryption enabled although ↵Mounir IDRASSI1-2/+5
this function does nothing when RAM encryption is disabled.
2019-02-28Windows: use specific order for EFI boot arguments memory regions that ↵Mounir IDRASSI1-8/+11
matches the one used by EFI bootloader.
2019-02-28Windows: Implement RAM encryption for keys on 64-bit machines using ChaCha12 ↵Mounir IDRASSI1-6/+48
cipher and t1ha non-cryptographic fast hash (https://github.com/leo-yuriev/t1ha)
2019-02-08Windows: Add implementation of ChaCha20 based random generator. Use it for ↵Mounir IDRASSI1-33/+9
driver need of random bytes (currently only wipe bytes but more to come later).
2019-02-08Windows: Add option to enable use of CPU RDRAND/RDSEED as source of entropy ↵Mounir IDRASSI1-3/+4
which is now disabled by default
2019-01-31Windows driver: better randomness for wipe bytes by always using Whirlpool ↵Mounir IDRASSI1-19/+28
hash of current time and random bytes retrieved using CPU RDRAND/RDSEED if available.
2019-01-28Increase password maximum length to 128 bytes from 64 bytesMounir IDRASSI1-5/+11
2019-01-20Windows driver: remove volumes master keys from CRYPTO_INFO since they are ↵Mounir IDRASSI1-3/+1
not needed after their key schedule is created
2019-01-20Windows: remove unused fields from CRYPTO_INFO structureMounir IDRASSI1-2/+1
2019-01-08Windows Security: Add new entry point in driver that allows emergency ↵Mounir IDRASSI1-2/+59
clearing of all encryption keys from memory. This entry point requires administrative privileges and it will caused BSDO when system encryption is active. It can be useful for example to applications that monitors physical access to the machine and which need to erase sensitive key material from RAM when unauthorized access is detected.
2019-01-08Windows Driver: erase system encryption keys from memory during ↵Mounir IDRASSI1-2/+2
shutdown/reboot to help mitigate some cold boot attacks
2018-03-05Windows: Add option to block TRIM command on system encryption SSD drives.Mounir IDRASSI1-0/+43
2017-07-04Windows Driver: correctly save and restore extended processor state when ↵Mounir IDRASSI1-6/+12
performing AVX operations on Windows 7 and later. Enhance readability of code handling save/restore of floating point state.
2017-06-23Update IDRIX copyright yearMounir IDRASSI1-1/+1
2017-06-23Crypto: Add optimized SHA-512 and SHA-256 assembly implementations for ↵Mounir IDRASSI1-2/+2
x86_64 and x86. This improves speed by 30%.
2016-12-25Windows driver: fix reading of boot PRF after latest EFI hidden OS changes. ↵Mounir IDRASSI1-37/+32
Better memory cleanup and changes for code clarity.

2016-10-17Windows: Fix false-positive detection of Evil-Maid attack during creation ↵Mounir IDRASSI1-2/+0
process of hidden OS by excluding the configuration byte in the boot sector whose value changes depending on the content.

2016-07-25Windows: solve benchmark issue for Whirlpool which caused wrong numbers when ↵Mounir IDRASSI1-4/+4
a 1GB buffer is chosen.

2016-04-19Windows: Add option to avoid PIM prompt in pre-boot authentication by ↵Mounir IDRASSI1-2/+3
storing PIM value unencrypted in MBR.
2016-02-07Windows Driver: if saving volume header fails, don't mark operation as ↵Mounir IDRASSI1-3/+5
successful so that it will be retried later.
2016-01-19Copyright: update dates to include 2016.Mounir IDRASSI1-1/+1
2015-12-21Windows: Implement PIM caching, both for system encryption and for normal ↵Mounir IDRASSI1-1/+4

2015-05-14Windows driver: avoid race condition by using ↵Mounir IDRASSI1-6/+10
IoAttachDeviceToDeviceStackSafe instead IoAttachDeviceToDeviceStack. Set BootArgs.CryptoInfoLength to 0 after clearing boot memory.
2015-02-09Static Code Analysis: in Windows Driver, avoid using uninitialized stack ↵Mounir IDRASSI1-0/+39
memory as random and use proper random value for wipe operation. Solve potential double-free issue.
2015-01-03Windows: change cascade encryption naming format to reflex mathematical ↵Mounir IDRASSI1-1/+1
composition of the encryption algorithm, thus being more clear. For example AES(Twofish(Serpent)) instead of AES-Twofish-Serpent.
2014-12-30Windows driver: don't fail if the PRF recovered from boot memory is not ↵Mounir IDRASSI1-7/+0
