What are cryptographic hashes?

Cryptographic hash functions are mathematical algorithms that convert an input of any length into a fixed-size string of bytes. They are designed to be one-way functions, making it computationally infeasible to reverse.

■ 02

How does it work?

Hash algorithms process input data through a series of mathematical operations that scramble and compress it into a fixed-length output. The same input always produces the same hash, but even tiny changes to the input c…
