Learn how hashing secures blockchain data, powers mining, and protects crypto networks from tampering and fraud.

Hashing is a one-way cryptographic function while encryption is designed to work both ways. Encryption algorithms take input and a secret key and generate a random looking output called a ciphertext.

People have been working on perfecting hashing since computing's early days. The result has been an almost endless number of hashing methods and tables. Facebook has faced this problem as well. Within ...

Researchers have found a new way to attack the SHA-1 hashing algorithm, still used to sign almost one in three SSL certificates that secure major websites, making it more urgent than ever to retire it ...
