aes256XtsEncrypt is XTS encryption mode with AES-256 single block cipher.

The algorithm reference is : “IEEE Standard for Cryptographic Protection of Data on Block-Oriented Storage Devices” The implementation is optimized for better performance in FPGA.

Parameters:

plaintextStrm	Input block stream text to be encrypted, each block is 128 bits.
endPlaintextStrm	End flag of block stream plaintext, 1 bit.
lenStrm	Total length of plaintext in bit, 64 bits.
cipherkeyStrm	Input two cipher key used in encryption, 256 bits.
IVStrm	Initialization vector for the fisrt iteration of AES encrypition, 128 bits.
ciphertextStrm	Output encrypted block stream text, 128 bits.
endCiphertextStrm	End flag of stream ciphertext, 1 bit.
