Maybe this is a newbie question:

Stream cypher, will XOR message bits with one-time pad bits.
Suppose I have a <a href="https://en.wikipedia.org/wiki/Pseudorandom_number_generator">pseudorandom number generator</a>, like a <a href="https://en.wikipedia.org/wiki/Mersenne_Twister">Mersenne Twister</a> or something similar. I could use the pseudorandom string to XOR the message.
Use the password as the seed of the generator. Same password = same pseudorandom sequence.
Could hashing blocks of the pseudorandom sequence create a stronger one-time pad stream?
