Stream ciphers, where plaintext bits are combined with a cipher bit stream by an exclusive-or operation (xor), can be very secure if used properly[citation needed]. However, they are vulnerable to attacks if certain precautions are not followed:
keys must never be used twice
valid decryption should never be relied on to indicate authenticity
