Xts-aes 256 frente a 128
XTS-AES 256-bit For removable drives, the same encryption algorithms can be used, however, BitLocker defaults to AES-CBC 128-bit. Here are two methods you can use to adjust the data encryption options. Please keep in mind that BitLocker applies the configured encryption method and cipher strength when you turn on BitLocker for a drive. The block size is 128-bit but the key is 256 bit key."Shown below" As such, AES-256 is medium term secure against a quantum attack, however AES-128 is broken, and AES-192 isn't looking too good. Source https://crypto.stackexchange.com/questions/6712/is-aes-256-a-post-quantum-secure-cipher-or-not AES 128 uses 10 rounds, AES 192 uses 12 rounds, and AES 256 uses 14 rounds. The more rounds, the more complex the encryption, making AES 256 the most secure AES implementation. It should be noted that with a longer key and more rounds comes higher performance requirements.

BLOWFISH. Designers Bruce Schneier First published 1993 Successors Twofish When AES_256_CM is used for encryption, AES_256_CM_PRF SHOULD be used as the key derivation function. AES-128 provides a level of security that is widely regarded as being more than sufficient for providing confidentiality.

Advanced Encryption Standard - Dr Mike Pound explains this ubiquitous encryption technique. n.b in the matrix multiplication In this tutorial, we will learn 1. What is AES 256 bit encryption, 2. 256 bit encryption example, Don't you want to be abreast of the Before the arrival of Advanced Encryption Standard (AES), information was sent over the internet using the Data Encryption Standard (DES) which was invented in 1970 with 56-bit key size. DES can rapidly transmit massive data at high speed with a symmetric key cipher. Using a powerful 256-bit encryption algorithm, AES Crypt can safely secure your most sensitive files.

Once a file is encrypted, you do not have to worry about a person reading your sensitive information, as an encrypted file is completely useless without the password.

AES is a block cipher. As with all block ciphers it MUST be used in a "mode of operation". As a result, users wanting AES-256 and AES-128 encryption must supply 512 bits and 256 bits of key respectively. On January 27, 2010, NIST released Special Publication (SP) 800-38E in final form. SP 800-38E is a recommendation for the XTS-AES mode of operation, as standardized by IEEE Std 1619-2007, for cryptographic modules. XTS-AES The Advanced Encryption Standard (AES) is a Symmetric Block Cipher.
