WebJul 18, 2024 · SHA-1 is a cryptographic hashing algorithm. This means that, in addition to the basic transformation operation, SHA-1 also guarantees certain security properties. Cryptographic hashing algorithms have two core characteristics: (1) Hash digests are unique. (2) Hashes cannot be reversed. WebOct 2, 2024 · A hash function can never be reversible because it is not lossless (perhaps with the exception of extremely short plain texts). That's why hash collisions are possible: two hashes may represent more than one plain text. The word "encoded" is often mixed up with "encrypted", but that's yet another story, to be told in another Stackexchange question. csusm arcgis
