Snefru

Snefru is a cryptographic hash function invented by Ralph Merkle in 1990 while working at Xerox PARC. The function supports 128-bit and 256-bit output. It was named after the Egyptian Pharaoh Sneferu, continuing the tradition of the Khufu and Khafre block ciphers. Snefru lives in the Hashing category of the fx menu.

Parameters

Parameter	Type	Required	Default	Description
Input	string	yes	—	Value to transform. Previous step output or a literal.
Size	number	no	128	Numeric value. Default 128.
Rounds	string	no	8	Choose one of: 8, 4, 2.

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

Returned value

Type	Description
string	Result of the Snefru transformation.

Limitations

• This operation treats Input as raw bytes (binary-capable). Non-text payloads may display differently after decoding.

Example

Run Snefru

Snefru is a cryptographic hash function invented by Ralph Merkle in 1990 while working at Xerox PARC. 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, Rounds and keep defaults unless your format requires otherwise.

3. Confirm Output value shows the transformed result.
