Free MD5 & SHA Hash Generator

Last Updated: August 13, 2026

Generate instant cryptographic hashes (MD5, SHA-1, SHA-256, SHA-384, SHA-512) for text strings or file uploads directly using the native Web Crypto API.

What is a Cryptographic Hash Function?

A cryptographic hash function is a mathematical algorithm that maps data of arbitrary size to a bit array of a fixed size (a digest). Hash functions are deterministic, one-way processes designed so that modifying even a single character in the input completely alters the output hash (avalanche effect).

Supported Hashing Algorithms

MD5: 128-bit hash algorithm for legacy verification and checksums.
SHA-1: 160-bit hash standard used in Git commit IDs.
SHA-256: 256-bit secure hash algorithm used in SSL certificates, Bitcoin, and modern security protocols.
SHA-512: 512-bit high-security hash algorithm for maximum entropy requirement.
