public file format

Suppose we want to transmit data that describes the details of a wire transfer. To do so, we use a public file format with
adequately sized fixed-length fields that specify the transaction details (account numbers involved, names of sender and
recipient, purpose of the transaction, amount to be transferred, time and date, a sequence number for the transaction). To
protect the data during transmission we encrypt it by means of a stream cipher: We produce a secret pseudo-random sequence
that is XORed bit-by-bit with the plaintext data specifying the wire transfer.
Why is this cryptographic protection inadequate, even if the stream cipher is accepted as being strong?
