WebSipHash - a short input PRF. ¶. SipHash is a cryptographically secure PRF – a keyed hash function – that performs very well for short inputs, hence the name. It was designed by cryptographers Daniel J. Bernstein and Jean-Philippe Aumasson. It is intended as a replacement for some uses of: jhash, md5_transform, sha1_transform , and so forth.

Why should I hash a random number when generating a secret?

WebRandomization is a family of techniques that alters the veracity of the data in order to remove the strong link between the data and the individual. If the data are sufficiently uncertain then they can no longer be associated with a specific individual. WebApr 26, 2013 · Hashing a non-cryptograpically secure random number is a form of security by obscurity, not a real security measure. It adds a step to figuring out the secret, which is probably why it's done, but it doesn't make the secret safe.
