Hash Generator

Generate MD5, SHA1, SHA256, and SHA512 hashes for text and files!
MD5: 128-bit hash (32 hex chars). Fast but cryptographically broken. Use only for checksums.
SHA-1: 160-bit hash (40 hex chars). Deprecated for security. Avoid for new applications.
SHA-256: 256-bit hash (64 hex chars). Secure and widely used. Recommended for most applications.
SHA-512: 512-bit hash (128 hex chars). More secure than SHA-256 but slower.

What are Hash Functions?

A hash function is a mathematical algorithm that transforms input data of any size into a fixed-size string of characters. The output, called a hash or digest, is unique to the input data - even a small change in input produces a completely different hash.

Hash functions are one-way operations, meaning you cannot reverse the process to get the original input from the hash. This makes them perfect for data integrity verification and password storage.
