Cryptographic hashes can be non-deterministic

WebFeb 5, 2024 · Typical hash functions are deterministic algorithms Random numbers may be used as part of an input to a hash function, depending on context Hashing is not related to encryption The two are sometimes used in conjunction, but encryption is not (typically) built from hash functions "stronger encryption" WebMay 4, 2024 · DETERMINISTIC Argument type: Case-insensitive Boolean string constant or 1 or 0. Use with ENCRYPT only. Boolean string constant values must contain one of {YES, TRUE, ON, 1, NO, FALSE, OFF, 0 }. Use this option when deterministic output is required. Controls whether encrypted value is DETERMINISTIC. The default value is FALSE.

WebFeb 25, 2024 · A salt makes a hash function look non-deterministic, which is good as we don't want to reveal duplicate passwords through our hashing. Let’s say that we have password farm1990M0O and the salt f1nd1ngn3m0. We can salt that password by either appending or prepending the salt to it. WebApr 5, 2024 · Hash functions must be Deterministic – meaning that every time you put in the same input, it will always create the same output. In other words, the output, or hash value, must be unique to the exact input. There should be no chance whatsoever that two different message inputs create the same output hash.
