WebHashing or hash is a common term when discussing blockchain technology. Hashing refers to the transformation and generation of input data of any length into a string of a fixed size, which is performed by a specific algorithm. In particular, the Bitcoin hash algorithm is SHA-256 or Secure Hashing Algorithm 256 bits. WebHash tables are used to quickly store and retrieve data (or records). Records are stored in buckets using hash keys Hash keys are calculated by applying a hashing algorithm to a chosen value (the key value) contained within the record. This chosen value must be a common value to all the records.

WebCRC24 Hash works by performing a series of bitwise operations on the input data, using a polynomial function to generate a binary sequence, and applying the CRC algorithm to each chunk of the binary sequence to generate a 24-bit output. The bitwise operations involve XORing the input byte with a predefined value and shifting the result to the left.
