Hash Generator

What is a Hash Function?

A hash function takes an input of any size and produces a fixed-size string of characters, called a hash or digest. The same input always produces the same hash, but even a tiny change in the input produces a completely different hash. Hash functions are one-way — you cannot reverse a hash back to the original input.

Hash Algorithm Comparison

MD5 produces a 128-bit (32 character) hash and is fast but considered cryptographically broken. SHA-1 produces a 160-bit (40 character) hash and is also deprecated for security use. SHA-256 (part of SHA-2 family) produces a 256-bit (64 character) hash and is widely used for data integrity verification and blockchain. SHA-512 produces a 512-bit (128 character) hash and offers the highest security among these algorithms.
