must_update_salt

Determines if a salt needs updating by calculating its current entropy based on length and character set, then comparing it against a required entropy threshold.

def must_update_salt(
    salt: string,
    expected_entropy: float
) - > boolean

Determines if the current salt provides insufficient entropy based on a required threshold.

Parameters

Name	Type	Description
salt	string	The existing salt string whose entropy is being evaluated.
expected_entropy	float	The minimum required bits of entropy the salt must satisfy.

Returns

Type	Description
boolean	True if the calculated entropy of the salt is less than the expected entropy, indicating an update is necessary.
