Why is it necessary to minimize redundancy in the ciphertext of a stream cipher?

I am utterly confused about this. I understand why you would want to minimize redundancy if you’re using a substitution cipher, but why is this necessary when using a stream cipher such as RC4? Since the attacker does not h… Continue reading Why is it necessary to minimize redundancy in the ciphertext of a stream cipher?
