A cryptographic hash function is a mathematical algorithm that takes an input (or 'message') and returns a fixed-length string of characters, which is typically a sequence of alphanumeric symbols.

No matter how large or small the input, the output of a hash algorithm is fixed in size; for example, Bitcoin hashes are 256 bits long. See SHA.

With a strong hash function it is almost impossible to reverse the hash value to its original content. The National Security Agency (NSA) designed the SHA-1 cryptographic hash function 10 years ago.

Hash Function: A computational algorithm that transforms an input (or 'message') into a fixed-size string of characters, commonly known as a digest, structured to be computationally infeasible to ...

Hash functions too use cryptography. A hash function is a mathematical algorithm that generates a fixed-length output based on the input data.

Schneier is part of the team of cryptographers who created Skein, a family of cryptographic hash functions that has been selected as one of the competition’s five finalists. The idea of ...

The vulnerability in the SHA-1 one-way hash function, which recently rocked the cryptographic world, is not seen as a threat to a new generation of one-time password products based on the ...

This hash function, named “Troika,” was developed by CYBERCRYPT’s expert cryptographers, and will lay a strong cryptographic foundation for the final IOTA protocol.

Chaotic hash functions represent a cutting‐edge convergence between nonlinear dynamics and cryptographic science. These functions employ chaotic maps—mathematical systems that exhibit extreme ...

Cryptographer Bruce Schneier says the upcoming SHA-3 cryptographic hash algorithm is not much better than the current one As the U.S. Department of Commerce’s National Institute of Standards and ...
