Hash Cracker

Educational tool: try a wordlist against MD5, SHA-1 or SHA-256 hashes to show how weak passwords fall fast.

⚠️ Educational tool. Only test hashes you own (e.g. your own old passwords). Cracking others' credentials is illegal.
Everything runs in your browser with WebCrypto — no hash is uploaded. This demonstrates why long, unique, random passwords beat dictionary words: even fast WebCrypto only gets through thousands of candidates here.
