Hash Generator

Generate MD5, SHA-1, SHA-256, SHA-384, SHA-512 hashes from text.

Input Text

Compare Hash (optional)

What is a Hash Function?

A cryptographic hash function takes any input and produces a fixed-size output (the hash or digest). The same input always produces the same hash, but even a tiny change in the input creates a completely different output. This property is called the avalanche effect.

Algorithm Comparison

Algorithm	Output Size	Security	Use Case
MD5	128 bits	Broken	Checksums, cache keys only
SHA-1	160 bits	Deprecated	Legacy systems only
SHA-256	256 bits	Secure	Digital signatures, SSL, blockchain
SHA-384	384 bits	Secure	Government, high-security systems
SHA-512	512 bits	Secure	Maximum security requirements

Common Use Cases

Verifying file integrity after downloads
Generating checksums for data deduplication
Creating cache keys for APIs and databases
Comparing file contents without reading entire files
Git commit hashes (SHA-1, migrating to SHA-256)

Features

5 algorithms: MD5, SHA-1, SHA-256, SHA-384, SHA-512
Real-time hashing as you type
Hash comparison to verify integrity
Security indicators for each algorithm
