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.
よくある質問
あわせて知りたいこと
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.
