As of Python 3.10 another quick way of hashing string to an 8 hexadecimal digit digest is to use shake.hexdigest (4) : import hashlib h=hashlib.shake_128 (b"my ascii string").hexdigest (4) #34c0150b. Mind the 4 instead of 8 because the digest is twice as long as the number given as parameter. WebMay 23, 2024 · Hashing is a transformation of an object into a numerical value. Functions that perform these transformations are called hash functions. For the sake of simplicity, let's consider hash functions that transform strings into array indexes, that is, into integers from the range [0, N] with a finite N.
