MD5 / SHA-256 Hash Generator

Cryptographic hash functions are algorithms that map arbitrary-sized data arrays into fixed-length checksum signatures. These hashes are strictly one-way mathematical calculations, meaning the original input text cannot be mathematically decoded or reconstructed from the hash output alone.

Cryptographic Security Criteria

A robust hash algorithm (such as SHA-256) is designed around strict operational rules:

1. Pre-image Resistance: It is computationally impossible to reverse y = H(x) to discover x.
2. Collision Resistance: Finding two discrete inputs x1 and x2 such that H(x1) = H(x2) requires exponential computing structures.
