What this tool does
Generate a 128-character hexadecimal SHA-512 hash for UTF-8 text, choose uppercase or lowercase, and copy the result.
- SHA-512 hex output is fixed at 128 characters.
- Changing the letter case does not change the digest itself.
- Hashing is suitable for integrity comparison, but is not equivalent to encryption or password storage schemes.
How to use it
- Enter any UTF-8 text.
- Select hexadecimal letter case.
- Click "Generate SHA-512".
- Copy and check the results where required.
Common uses
- Generate longer content fingerprints.
- Check whether the text has changed before or after transmission.
- Cross-validate with SHA-512 results from the command line or other implementations.

FAQ
Why is SHA-512 output 128 characters?
512 bits equals 64 bytes, each byte represented by two hexadecimal characters.
Is SHA-512 an encryption algorithm?
No. It generates irreversible digests and does not provide decryptable ciphertext.
Can I hash an empty string?
Yes. The empty string also has a standard and deterministic SHA-512 digest.
Does the tool send input?
No. Your text is processed only in your browser and is never uploaded.
