SHA3-512
Calculate a SHA3-512 hash from text using UTF-8, Hex, Base64, and other input encodings. Read more
What is SHA3-512?
SHA3-512 is a fixed 512-bit cryptographic hash standardized in NIST FIPS 202. It uses the SHA-3 sponge construction, unlike SHA-512 from the SHA-2 family. It also differs from the original Keccak-512 submission because standardized SHA-3 uses a different domain-separation suffix.
How to use this hash calculator
Enter the text, select how it should be encoded into bytes, and choose the output format. A SHA3-512 digest is always 64 bytes, displayed as 128 characters in Hex.
Result example
SHA3-512 of UTF-8 abc is b751850b1a57168a5693cd924b6b096e08f621827444f70d884f5d0240d2712e10e116e9192af3c91a7ec57647e3934057340b4cf408d5a56592f8274eec53f0 in Hex.
Important limitations
SHA3-512 is not encryption and an unkeyed digest does not authenticate the message. A large output does not make a fast hash appropriate for password storage; use a password-hashing function designed for that purpose.
Frequently asked questions
Why does my result differ from another tool?
Verify the algorithm is SHA3-512—not SHA-512 or Keccak-512—then check the input bytes, encoding, and line endings.
Can I use the result to verify data?
Yes, if the expected SHA3-512 digest is obtained from a trusted source. For raw file bytes, use SHA3-512 File Hash.
