Jul 26	comment	Can hash functions be used with CTR or OFB mode? @Tie-fighter I have found an interesting encryption system: Snuffle. link. That's just my idea.

Jul 18	comment	Can hash functions be used with CTR or OFB mode? I have included an example in my question. Hope this will make it clear. In CTR mode, I do not need to decrypt anything. To decrypt, one only need to regenerate the correct keystream(then bitwise XOR with the ciphertext).
Jul 17	revised	Can hash functions be used with CTR or OFB mode? Add an example(see p.s.2)

Jul 17	comment	Can hash functions be used with CTR or OFB mode? Block cipher mess up the input block with a key, so can a hash function. Another fact: CTR is plaintext independent, so as long as we can generate and reproduce a keystream, we can encrypt and decrypt, with no relation to a cipher's decrypt method. This is odd to me.
Jul 17	comment	Can hash functions be used with CTR or OFB mode? I don't think I have made concepts wrong. Block ciphers can be used as stream ciphers when combined with certain modes of operation, e.g. CTR, OFB. Please refer to link.
Jul 17	answered	Why are hash functions one way? If I know the algorithm, why can't I calculate the input from it?
