We will be implementing sha256 which comes under the shah-2 series which is a robust hashing algorithm for now. WitrynaSince python's build-in hash function is randomly seeded (and applies to a few data types only) it is not suited for persistent caching. Alternatively, standard hash functions, as provided by the hashlib library, can be used. As they relay on byte sequences as input, python objects need to be converted to such a sequence first. highland ag services
