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

But competition entrants face another major challenge. While encryption algorithms rely on keeping a “key” secret from attackers, cryptographic hash functions can have no such secrets.

Despite being something of a cryptography veteran, SHA-1 hash algorithm faces an uncertain future as OpenSSH and Libssh choose to block it.

The Proof of Work algorithm is not just a technical aspect of Bitcoin; it's a testament to the length's humanity will go to ensure trust in a trustless environment.

Such hash algorithms are ultimately one of the key security technologies for federal and public systems. The competition is NIST’s response to recent advances in the analysis of hash algorithms.

Because hashing algorithms works in one direction, the only way to obtain the corresponding plaintext is to guess, a process that can require large amounts of time and computational resources. The ...

The SHA-1 hashing algorithm, still used to sign almost one in three SSL certificates, can now be attacked for as little as $75,000, and should be urgently retired, researchers say ...

Proof-of-activity is the blockchain consensus algorithm that uses a combination of proof-of-work and proof-of-stake to create blocks and verify data integrity.

Researchers say the SHA-1 hashing algorithm, still used to sign almost one in three SSL certificates, should be urgently retired Researchers have found a new way to attack the SHA-1 hashing ...
