It is defined for three different block sizes: 256 bits, 512 bits, and 1024 bits. The key is the same size as the block, and the tweak value is 128 bits for all block sizes. Threefish was created in 2008 as part of the Skein hash function, a submission to NIST’s SHA-3 competition. Webstorage. XTS-AES is a tweakable block cipher that acts on data units of 128 bits or more and uses the AES block cipher as a subroutine. The key material for XTS-AES consists of a data encryption key (used by the AES block cipher) as well as a “tweak key” that is used to incorporate the logical position of the data block into the encryption. tasmania stranded pilot whales
