Hash Generator

使用方法

1. Type or paste any text into the input area。
2. Select the algorithm: SHA-1, SHA-256, SHA-384, or SHA-512。
3. Copy the hexadecimal digest from the output field。
4. All computation runs in your browser via the WebCrypto API — nothing is stored or sent anywhere。

範例

• Hashing "hello" with SHA-256 produces 2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824。
• Switching to SHA-512 for the same input produces a 128-character hex digest, twice as long。
