Using hashing, We can easily access or search the values from database. Part 2 will describe the accelerated implementation of AES encryption using hardware instructions that are part of the same instruction set. AES is a 128 bit / 16 byte block cipher and it is therefore not possible to use PKCS#5 compatible padding, as it is only defined for 64 bit / 8 byte block ciphers.
