我一直都想整，但唔識

信唔過bitlocker既贊成用opensource既Veracrypt

btw, AES 128Bits同256Bits無咩分別
佢crack到128bits既話256bits都應該可以用同樣方法crack

http://www.axantum.com/AxCrypt/etc/seagate128vs256.pdf
• NIST1
has, in the reference document,
concluded and recommended that all three
key-lengths (128-bit, 192-bit and 256-bit) of
AES provide adequate encryption until beyond
calendar year 2031.
• NIST’s recommendation above includes the
threat model not only of predicting the key, but
also of cracking the encryption algorithm. The
difference between cracking AES-128 algorithm
and AES-256 algorithm is considered minimal.
Whatever breakthrough might crack 128-bit will
probably also crack 256-bit.

幾千蚊砌機無錢買正版win10?

btw bitlocker絕對係軍用級保密技術

OEM既話好平200-300

簡單黎講OEM組係你條KEY淨係可用一次
換左機唔可以用同一條KEY

bitlocker解鎖係喺入os之前喎， crack window login邊關bitlocker事？

我做咁耐未聽過有人破到
你揾到方法唔該你示範下

呢個我都唔肯定, 未試, 但寧願唔開 autounlock 個功能
想試下野
1. encrypt E drive (non-system drive)
2. enable auto unlock
3. force reset administrator password
4. login
5. 睇下 auto unlock 仲識唔識 auto unlock, 如果識的話, 係好撚大問題, 唔好用 auto unlock 個功能

係真唔係呀？ TrueCrypt 嘅死因好似一直都冇 confirm 過， 有好多陰謀輪

無可否認理論上係256bits比較安全 但實際上就無咩分別
美國佬驚人access到比依家更快super computer or even quantum computer姐
唔覺得狗有咁既能力
當然記得既話更係set 256bits 啦
但係唔記得既巴絲都唔洗咁驚比人破解到
最緊要記得出門要關機

試下 唔好用推 試下講：

AES 128 已經夠 popo 玩 48 個鐘
加埋 bios password
Windows password
再多幾個鐘
到真正入到 OS 後先開始正式屈 CP

On NIST’s recommendation, the new cipher was formally adopted by the US federal government and came into effective use in May 2002. Like DES before it, AES was awarded FIPS status. The US government considers all AES key sizes to be sufficient for classified information up to the "Secret" level, with "Top Secret" information requiring AES-192 or AES-256.

人地美國佬既TOP SECRET文件係用AES 256 bits加密。

AES 128 bits一定唔係48個鐘，但無謂因為少少peformance hit而令到個加密程度減低，反正宜家新既CPU大部份有hardware AES加/解密功能，AES 256 bits同AES 128 bits係效能上唔係太大分別。

咁痴線 ? 咁講 AES 咪已經唔安全? 不過 crypto 嘅野唔係好識想問下
如果我用記事本打 "12345678" 後 bitlocker 條 key AES 加密咗個 secret.txt
假設用記事本打返個 file 見到個 ciphertext 係 "abcdefg"
印象中理論上要破解個流程只針對 ciphertext "abcdefg" , 而唔係直接破解條 key.

簡單來說個情況係如果破解 secret.txt 要用 1 個鐘, secret2.txt 又要用1一個鐘, secret3.txt 又要用1一個鐘... 如事者應該係破到 2049
但係如果係直接對條 key 進行破解的造, 假設我破解到條 key, 條 key 可以 apply 落其他 file 度. 咁就好大問題...

實際黎講係以上邊個情況?

佢應該係講緊 硬件加速 唔係破你條KEY
姐係CPU包埋類似TPM既功能
