  3. import EasyCrypt
    keystring = "SixteenByteKey!!"
    inpstring = "Some super secret string, that I don't want you to see."
    # This is the initialisation vector/nonce. I generated it with the below code. As you
    # will need it to decrypt later on, you might want to store it and not just generate it each time
    # I just generated it like this and printed this one out to store it.
    #
    # import os
    # from binascii import hexlify, unhexlify
    # ivstring = hexlify(os.urandom(16)).decode()

    ivstring = "aba0a3bde34a03487eda3ec96d5736a8"

    crypted = EasyCrypt.encrypt_string(keystring, inpstring, ivstring)
    print(crypted)

    decrypted = EasyCrypt.decrypt_string(keystring, crypted, ivstring)
    print(decrypted)
