WebJan 30, 2024 · To hash a sequence of strings unambiguously, so that any two different sequences yield a different hash, you could prepend every string with its length, e.g. by using decimal representation followed by a separating character (e.g. hyphen). For the strings "abc" and "de" and "" (empty string) and "f" this would look so: hash("3-abc2-de0 … WebFeb 27, 2024 · What Is a Hash? Hashing is the method used for compressing data. Still, it’s not the typical compression everyone knows, like a .zip or .rar file. Hashing creates a code for the data using a hash algorithm. The code represents a string of characters, which act as a “fingerprint” of that file.

"WebMar 3, 2024 · A hash is just a symmetric cipher run in a loop, encrypting the input using a key also from the same input, and often with extra stuff sprinkled in as you go (e.g. prime remainders in SHA-2). I'm no expert, but whether or not any hash is quantum-resistant boils down entirely to whether or not the symmetric cipher chosen for the hash is. " - Hash computing

WebHash function coverts data of arbitrary length to a fixed length. This process is often referred to as hashing the data. In general, the hash is much smaller than the input data, hence hash functions are sometimes called compression functions. Since a hash is a smaller representation of a larger data, it is also referred to as a digest.
