- In cryptography, a
keystream is a
stream of
random or
pseudorandom characters that are
combined with a
plaintext message to
produce an

digit stream (
keystream). In a
stream cipher, each
plaintext digit is
encrypted one at a time with the
corresponding digit of the
keystream, to give a digit...
- insecure. It is
especially vulnerable when the
beginning of the
output keystream is not discarded, or when
nonrandom or
related keys are used. Particularly...
