Hash Generator

A cryptographic hash function takes an arbitrary-length input and produces a fixed-length output (the hash or digest) with three key properties: determinism (the same input always produces the same output), avalanche effect (a tiny change in input causes a dramatically different output), and one-way computation (it is computationally infeasible to reverse the hash to find the original input). Different hash algorithms produce digests of different lengths and offer different security guarantees. MD5 (128-bit) and SHA-1 (160-bit) are broken for security use but remain useful for checksums. SHA-256 (256-bit) is the current industry standard. SHA-512 (512-bit) offers the highest security margin. Computing multiple hashes at once lets you cross-verify data, satisfy requirements for systems that use different algorithms, and compare the performance characteristics of each.
