SHA-3, originally known as Keccak is a cryptographic hash function/algorithms designed by Guido Bertoni, Joan Daemen, Michaël Peeters, and Gilles Van Assche, building upon RadioGatún. SHA-3 uses the sponge construction in which message blocks are XORed into the initial bits of the state, which is ...
On the 2nd of October NIST decided that SHA-3 is the new standard hashing algorithm, does this mean we need to stop using SHA-2 as it is not secure? What is this SHA-3 anyway?
Keccak is the winner of the SHA3 competition. Since Keccak is highly customizable (presumably for security/memory/time/speed tradeoffs) there does seem to be some controversy around how Keccak ...
Possible Duplicate: What is SHA-3 and why did we change it? SHA-3 has been finalized! So, what does secuirty.se think about the new hash funciton? Should we start replacing all uses of md5/...
I noticed in the new SHA-3 standard that it has a variable output size. Knowing that longer output is obviously better (higher entropy), what is theoretical the lower limit of the output size? Can my ...
Bitcoin stores its addresses as a combined SHA256 + RIPE-MD160 hash. Is it correct to assume this is done to prevent a failure in the algorithm? Since SHA3 was designed to be an alternative to SHA256,...
