Hash & checksums
SHA-512 Generator
Create SHA-512 hashes locally in the browser using the Web Crypto API.
How to use this tool
Paste text into the input field.
The SHA-512 digest is generated locally in your browser.
Copy the digest for checksum, comparison, documentation, or systems that specifically require SHA-512.
SHA-512 versus SHA-256
SHA-512 produces a longer digest than SHA-256 and belongs to the SHA-2 family.
It can be useful where a system or policy specifically asks for SHA-512.
For many web and release-checksum workflows, SHA-256 remains the more common default.
Security boundaries
SHA-512 is a hash function, not encryption. It does not hide the original message if the input can be guessed.
For passwords, use a slow salted password hashing algorithm such as Argon2id, bcrypt, or scrypt instead of a plain SHA-512 digest.
For authenticated messages, use HMAC-SHA-512 rather than concatenating a secret with a message.
Examples
Policy-required digest
Use SHA-512 when a compliance document, API, or artifact repository specifically requests that algorithm.
Byte-level comparison
If two strings produce different SHA-512 digests, their bytes are not identical.
FAQ
Is SHA-512 stronger than SHA-256?
It has a larger digest size and different performance characteristics, but SHA-256 is already a strong default for most checksum workflows.
Can SHA-512 be decrypted?
No. Hashes are one-way digests, not encrypted messages.
Should I use SHA-512 for passwords?
Not as a plain hash. Use Argon2id, bcrypt, or scrypt for password storage.
Is the input uploaded?
No. SHA-512 generation runs locally in your browser.
