Mapping File
Definition
A Mapping File is a private file that serves as the only key to recover the Original Secret from the Decoy Text. It stores mapping information in the form of structured technical data, not the original sensitive data itself.
Without the correct Mapping File, recovering the Original Secret is impossible, even if the Decoy Text is fully available.
Characteristics
A Mapping File has the following key characteristics:
Stored as a
.jsonfileDoes not contain the Original Secret
Contains structured ASCII data, not secret text
Safe when standing alone
Highly sensitive as a recovery component
Deterministic and sequential
The Mapping File is designed so that it cannot be interpreted or used directly, even if the file is exposed.
What it contains
Technically, a Mapping File contains:
95 standard ASCII characters repeated in a controlled manner
The Mapping File includes all 95 standard ASCII characters (A-Z, a-z, space, 1-0, and symbols), where each character is repeated up to the highest frequency of any character found in the original seed phrase or sensitive data.
The data is arranged sequentially
This structure ensures that:
The Mapping File does not contain only the characters used in the sensitive data
There is no way to determine which characters are relevant
There is no information about the order, value, or content of the Original Secret
With this approach, the Mapping File remains safe even when standing alone, because its contents are a complete character set obscured through frequency and ordering, not a direct representation of sensitive data.
Where it can be store
A Mapping File can be stored anywhere that supports .json files, with one primary rule:
It must be stored separately from its related Decoy Text.
Example storage locations include:
Local devices (computers, mobile phones, flash drives, external drives)
Offline media
General digital storage
Permanent storage for long-term archiving or inheritance purposes
