Also the latter has a block property which would enable you to rebuild the stream from any place you want - that property violates a CSPRNG prerequisite that something like HASH_DRBG has - mainly that recovery of the current state should not betray the past states. That said, you can use HASH_DRBG or some variant of it to construct a stream cipher that is as secure as that hash function provided you don't screw up the implementation, it will just not be used. SSL for example, puts a big strain on the server, no one wants it worse. | |
