ContainsSeparator(string?)

Reports whether a value carries a character this identity separates its own fields with.

public static bool ContainsSeparator(string? value)

Parameters

value string

A rule name, a condition, or an account identifier about to become part of a rule set.

Returns

bool

true when the value would blur the boundary between two fields of the digest input.

Remarks

The remarks above say a separator cannot occur in what is hashed, and this is what lets that be true rather than hoped for: whatever binds a rule set asks first and refuses a value that answers yes. Without the check the claim rests on the expression language's grammar, which is somebody else's decision and can change under this one — and a rule set that renders identically to a different rule set is exactly the collision this identity exists to make impossible.
