  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)
