There were lots more, but I really liked the ones above.When it comes to the forensic investigation of Apple devices, a Keychain analysis is of particular importance. Lecture 8: Advanced Encryption Standard (AES) by Christof Paar (Love his accent, and the whole lecture series looks great!) You Don't Want XTS (This guy is a *genius*!!) Not doing a good job tying the FileVault 2 encryption process with the AES-XTS process.įWIW, the articles and videos I studied in just encryption were very educational, including:.WTF? When you are talking about 10 moving parts, "it" is a poor choice?! Talking about decryption in one sentence and immediately flipping to encryption in the next sentence.(Things are complicated enough it is foolish to say, "Just reverse them!") Too much emphasis on "decrypting" without first explaining the "encryption" process.Why does the paper not even have a date on it?.Some of my pet peves includes things like: While I did learn some reading these two documents, the poor writing made things much more difficult than need be.

Decrypt Keychain.Plist zip file#
If an encrypted zip file is decrypted with the wrong key, then the start and end are garbage.Ĭlick to my frustration was with the authors of these documents: If that data is decrypted with the wrong key, then that structure will be incorrect.Īn example in a non-disk-encryption case is a ZIP file, which starts and ends with specific identifiable data.
Decrypt Keychain.Plist software#
The software can also rely on the fact that the header or other initial structural data of the disk volume is a "known message", in the sense that it has an expected structure and expected values. Then the encrypted known message is decrypted and hashed. Instead, a hash of it can be stored (in plaintext). The known message doesn't need to be revealed or stored anywhere in plaintext. If the message doesn't decrypt correctly, then the key is incorrect. Instead, the software can use the provided key to decrypt a known message. It's not necessary to store the key, or to compare it. These are unnecessary, and would undermine security:

Decrypt Keychain.Plist code#
(The description above is the standard way that you would code a "Log in" screen for an application/website.) If the hashed value doesn't match, then you cannot access your hard-drive or the data on it. If the hashed value matches yours "encyption key" then macOS unlocks (i.e. macOS then compares this hashed value against the stored "encryption key" on your hard-drive. salting + some algorithm) and creates a hashed value. Later on when you start up your Mac, and log in, macOS takes your login password, runs it through the same process it used earlier (e.g. macOS also stores this "encryption key" somewhere on your hard-drive. macOS uses this "encryption key" to encrypt your entire hard-drive. (Presumably it takes your login password, "salts" it, runs it through some fancy algorithm, and produces a hashed value which serves as your "encryption key".) macOS takes your login password and somehow creates an "encryption key". Can someone help me to better understand the technical details of how full-disk encryption (FDE) works with FileVault2 on a Mac?
