If I lose my external HDD and somebody finds it and tries to hack, will he succeed?Is it possible to get data from encrypted disk by disassembling it and working with platters?
HDD is APFS AES 256 encrypted and has strong password.

I’m using a MacBook and want to store confidential data (financial documents, passwords, private photos, etc.) on an external HDD disk.
How safe is setting up APFS AES 256 encryption with disk utility?
Does HDD brand and model matter for … Continue reading Is it safe to store data on APFS 256 AES encrypted external HDD disk?
This is a dumb crypto mistake I had not previously encountered:
A developer says it was possible to run their own software on the car infotainment hardware after discovering the vehicle’s manufacturer had secured its system using keys that were not only publicly known but had been lifted from programming examples.
[…]
“Turns out the [AES] encryption key in that script is the first AES 128-bit CBC example key listed in the NIST document SP800-38A [PDF]”.
[…]
Luck held out, in a way. “Greenluigi1” found within the firmware image the RSA public key used by the updater, and searched online for a portion of that key. The search results pointed to a common public key that shows up in online tutorials like “…

I use hybrid encryption. AES CBC as a symmetric cipher. The key is derived from shared secret using curve25519 (receiver’s public key is known). The sender’s private key is randomly generated, the public key is sent along with the encrypte… Continue reading Is it secure to have constant initialization vector for symmetric block cipher when using hybrid encryption scheme?
so as the title describes, i am trying to get the IV using the key, encrypted data, and plaintext data.
According to wiki, AES CBC uses the IV to XOR the first block of plaintext data with the IV, then encrypts the xor’d data, and doesnt u… Continue reading Getting AES-CBC IV using key, encrypted data, and plaintext data [closed]

I’m trying to create a tool to create secure passwords and sends them to the client – previously I’ve used passwordsgenerator and pwpush.com for this. Unlike pwpush I don’t want to store passwords in a db to delete later. My application wo… Continue reading Is my use of AES for password sharing secure?

I am rewriting a php code in Java 8 where Rijndael-128 cipher (AES) is being used for encryption decryption. The IV being used is 16 characters (128 bit) long, but the key being used is 18 characters (144 bit) long.
I have tried to write e… Continue reading Using random block size for Rijndael-128 with CBC mode [migrated]
