Using double hashing schema to reduce short hash handle collisions and improve memory allocation in content-addressable storage systemsExample embodiments of the present invention relate and a method and an apparatus for double hashing. The method including receiving a hash signature, including a short ...

Is hashing a password twice before storage any more or less secure than just hashing it once? What I'm talking about is doing this: $hashed_password = hash(hash($plaintext_password)); instead of just this: $hashed_password = hash($plaintext_password); If it is less secure, ...
All of these derive the requisite Bloom filter indices (often 6 of them for ~1% FP @ 10 bits/key) from a single 32-bit hash value using variations on double hashing. The original leveldb implementation cites [Kirsch,Mitzenmacher 2006] ("Less Hashing, Same Performance: Building a Better Blo...
The data which is gathered by means of this technology is encrypted using a non-reversible one-way function ( “hashing”). The data is directly pseudonymised and is not used in order to achieve personal identification of the users of this website. However, there is identification of the ...
