SHA3

The SHA-3 (Secure Hash Algorithm 3) hash functions were released by NIST on August 5, 2015. Although part of the same series of standards, SHA-3 is internally quite different from the MD5-like structure of SHA-1 and SHA-2. SHA-3 is a subset of the broader cryptographic primitive family Keccak designed by Guido Bertoni, Joan Daemen, Michaël Peeters, and Gilles Van Assche, building upon RadioGatún. SHA3 lives in the Hashing category of the fx menu. See SHA-3 for format details.

Parameters

Parameter	Type	Required	Default	Description
Input	string	yes	—	Value to transform. Previous step output or a literal.
Size	string	no	512	Choose one of: 512, 384, 256, 224.

Input is the primary value (previous step output or a literal).

Returned value

Type	Description
string	Result of the SHA3 transformation.

Limitations

• This operation treats Input as raw bytes (binary-capable). Non-text payloads may display differently after decoding.
• Wrong key, algorithm options, or malformed input typically raises an evaluation error — fix Input or options before re-running.

Example

Run SHA3

The SHA-3 (Secure Hash Algorithm 3) hash functions were released by NIST on August 5, 2015. Adjust optional parameters when the defaults do not match your payload.

1. Set Input to the value to transform (previous step output or a literal).

2. Review Size and keep defaults unless your format requires otherwise.

3. Confirm Output value shows the transformed result.
