SHA0

SHA-0 is a retronym applied to the original version of the 160-bit hash function published in 1993 under the name ‘SHA’. It was withdrawn shortly after publication due to an undisclosed ‘significant flaw’ and replaced by the slightly revised version SHA-1. The message digest algorithm consists, by default, of 80 rounds. SHA0 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.
Rounds	number	no	80	Numeric value. Default 80.

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

Returned value

Type	Description
string	Result of the SHA0 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 SHA0

SHA-0 is a retronym applied to the original version of the 160-bit hash function published in 1993 under the name ‘SHA’. 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 Rounds and keep defaults unless your format requires otherwise.

3. Confirm Output value shows the transformed result.
