Xts aes 128 frente a aes 256
Difference on 128 bit vs 256 bit: 256 bit is more "secure" - harder to calculate.

APP_CIPHER=AES-256-CBC. It solved the issue and created a 32 character long string. Thanks for the help anyways, would not have looked here without you. I got a env file.

As already noted as a consequence of this attack an additional four rounds were added to AES-128 in order to improve its safety margins. AES-128 provides more than enough security margin for the [foreseeable] future. But if you’re already using AES-256, there’s no reason to change. people need to pay attention. But paying attention and evaluating doesn’t always mean agreeing. Briefly, there is a long-known problem with how AES deals with 256-bit AES keys. Pointer to a buffer containing a valid AES key key2 is used to encrypt the tweak (Key2 in IEEE Std 1619-2007).

Given exponential progress making quantum computing ever more a reality, I was thinking to increase the key size. I believe that AES is only defined on key sizes of 128, 192 and 256 bits, but cryptsetup/LUKS does allow me to select a key size of 384 or 512 bits. Give our aes-128-xts encrypt/decrypt tool a try! aes-128-xts encrypt or aes-128-xts decrypt any string with just one mouse click. Per Klick auf „Aktiviert“ siehst du die Standardeinstellung AES-128. BitLocker Group Policy Standardwerte: AES-128 Empfohlene BitLocker Einstellung. Natürlich empfehle ich eine Umstellung auf XTS-AES 256 bevor du deine BitLocker Verschlüsselung startest.

… AES comprises three block ciphers, AES-128, AES-192 and AES-256. Each cipher encrypts and decrypts data in blocks of 128 bits. When more than 128 bits are processed the method used is known as a mode of operation and there are different modes for … The BitLocker encryption algorithm is used when BitLocker is first enabled. The algorithm sets the strength for full volume encryption. Available encryption algorithms are: AES-CBC 128-bit, AES-CBC 256-bit, XTS-AES 128-bit, or XTS-AES 256-bit encryption. The default value is XTS-AES 128-bit encryption. La encriptación basada en hardware AES de 256 bit, con modo de cifrado por bloques XTS, que ofrece mayor protección de los datos que otros modos de cifrado por bloques, como CBC y ECB, se utiliza en las unidades flash USB DT 4000G2 y DTVP 3.0 de Kingston.

The program sets up a 256 bit key and a 128 bit IV. This is appropriate for the 256-bit AES encryption that we going to be doing in CBC mode. Make sure you use the right key and IV length for the cipher you have selected, or it will go horribly wrong!! For instance, a 128-bit AES key, which is half the current recommended size, is roughly equivalent to a 3072-bit RSA key in terms of the actual security they provide. It’s also important to understand the difference between security claim and security level.
