Up to 1 MiB of UTF-8 text. Processing stays in your browser.
Enter text to generate a digest.
SHA-512 is a one-way hash, not encryption. It cannot decrypt or reliably recover the original text.
使用步骤
如何使用
- Enter or paste text into the input field.
- Click Generate SHA-512.
- Copy the hexadecimal digest if needed.
Runs locally in your browser
The page uses the browser Web Crypto API. Your input is encoded as UTF-8 and is not uploaded or sent to a third-party service.
A 512-bit one-way digest
SHA-512 is designed to be one-way. The digest is useful for comparison and integrity checks, but it cannot decrypt or reliably recover the original text.
Fixed output length
Every SHA-512 result is 512 bits, shown as 128 lowercase hexadecimal characters.
常见问题
你可能还想知道
Can SHA-512 decrypt text?
No. SHA-512 is a one-way hash, not encryption, so it cannot be reversed to recover the original input.
Is my text uploaded?
No. Hashing happens locally in your browser through the Web Crypto API.
Why is the result 128 characters?
SHA-512 produces 512 bits. Written as two hexadecimal characters per byte, that is 128 characters.
