Module proxy_reencryption_lib::utils

This module provides various cryptographic utilities.

It includes functions for hashing, XOR operations, encryption, and generating random arrays.

The hash function computes the SHA-256 hash of the input data and returns the first 16 bytes.

The xor function performs a bitwise XOR operation on two arrays of the same size.

The encrypt function encrypts a 128-bit plaintext using AES-128 in ECB mode.

The new_random_arr function generates a new random array of a specified size.
