Features
Four Hash Algorithms
Generate MD5, SHA-1, SHA-256, and SHA-512 hashes simultaneously from a single input.
Web Crypto API
SHA hashes use the browser's native Web Crypto API for fast, secure computation.
Real-Time Hashing
Hashes update instantly as you type, so you always see the current result.
100% Local
All hashing is performed in your browser. Your text never leaves your device.
FAQ
どのアルゴリズムを使うべき？
SHA-256が推奨。MD5とSHA-1はセキュリティには弱いですがチェックサムには十分。
ローカルで処理されますか？
はい、SHAはWeb Crypto API、MD5はローカル実装。ブラウザ外に出ません。
