SHA-512 Hash Generator
Generate the SHA-512 hash of any text in your browser. 512-bit digest, 128 hex characters, fully private.
Independently verified for accuracy
Calculator by Toolsloft ↗Enter any text and this tool returns its SHA-512 hash, a 512-bit value shown as 128 hexadecimal characters. SHA-512 is the largest member of the SHA-2 family and is used where a longer digest is preferred, such as certain password hashing schemes and high-integrity checksums. The work is done locally in your browser.
How this is calculated
The hash implements SHA-512 from FIPS 180-4, operating on 64-bit words: your UTF-8 text is padded to 1024-bit blocks and run through 80 compression rounds. We check the JavaScript against Python's hashlib on every build, so the output lines up with any standard SHA-512 tool.

Examples
- Text:
abc → ddaf35a193617abacc417349ae20413112e6fa4e89a97ea20a9eeee64b55d39a2192992a274fc1a836ba3c23a3feebbd454d4423643ce80e2a9ac94fa54ca49f
FAQ
- How is SHA-512 different from SHA-256?
- Both are in the SHA-2 family, but SHA-512 works with 64-bit words and produces a longer 512-bit digest (128 hex characters) instead of 256 bits. On 64-bit machines it can even be faster while giving a wider hash.
- How long is a SHA-512 hash?
- Always 128 hexadecimal characters, since SHA-512 outputs a fixed 512-bit digest no matter the input.
- Is a hash the same as encryption?
- No. A hash is a one-way fingerprint and cannot be decoded back to the original text. Encryption is reversible with a key; hashing is not.
