I was reading how AES can be used for 64 bit data. Than i came to this answer :Is it possible to implement AES with a 64-bit I/O block size?
The answer here is given that by running AES in counter stream mode 64 bit plain text produce the 64 bit cipher text. But i can't under this point when 128 bit cipher text produced by AES block cipher is
XOR with 64 bit plain text. How it produce 64 bit output?
