Cryptography hash meaning
WebSHA1 is a cryptographic hash function that takes input data and produces a fixed-size output, known as a hash or message digest. It was developed by the United States National Security Agency (NSA) and published as a federal standard in 1995. ...

WebMay 27, 2024 · A hash function has a specific output size while the function can handle any sized messages. So if you argue from that point of view, a hash is always irreversible as there are many messages that have the same hash. However I wonder if this is the correct definition of "irreversible". In cryptography, would irreversible mean that we cannot ...
