WebQuantum computers can, in theory, reduce the effective entropy of a cryptographic key in half. Thus, if you want 128 bits of effective entropy (and the key needs to last long enough for quantum computers to reach the ability to operate on significant-length keys), you should use 256 bits of random data. Share. WebCryptographically secure hashes usually work on bitstrings of arbitrary length and output a fixed length bitstring. The secure part is being collision resistant and preimage resistant, so that you have a practical oneway function, and those are the properties you want for "scrambling"..
