Seed Tag Files

seed_tag v4 (2025-10-08): new algorithm 

how it works (in the program, this process occurs automatically, 
but the entire packaging/unpacking process can be reproduced manually, 
this will require a hash512 calculation site from a string and a calculator in programmer mode):

default settings (for example):

Number — 123123
Password — 123
Email — 123
Seed phrase (first 24 words from bip39 dictionary) — 
abandon  ability  able    about  above    absent  
absorb   abstract absurd  abuse  access   accident  
account  accuse   achieve acid   acoustic acquire  
across    act      action  actor  actress  actual

(Instead of the words of the seed phrase,
 it is allowed to use the numbers of their position 
 in the bip39 dictionary.)

when you press  button «Pack original seed»
1. string s=Number+Password+Email
s=123123123123
 (NumberPswEml)
e.g. if Number=123456
        Password=password
        Email=email@server
     then s=123456passwordemail@server  
 
2. string hash512=HASH512(s)
use https://sha512.online/ to get hash512 for any string

for default s=123123123123
  hash512=158911a3463559821b81c9d7bb29ebf3a8d6a8d33a3bc0dc45c44ac4af6ebe500ae7df8f96b9570fa615286bb161a74ab1d0ac0f01354e21fd597b45bff0f73b
  
for s=123456passwordemail@server

3. Generate fake seed
3.1 For each word of the seed phrase, three characters from hash512 are taken. 

for default hash512=158911a3463559821b81c9d7bb29ebf3a8d6a8d33a3bc0dc45c44ac4af6ebe500ae7df8f96b9570fa615286bb161a74ab1d0ac0f01354e21fd597b45bff0f73b
158      911      a34     635    598      21b 
abandon  ability  able    about  above    absent  

81c      9d7      bb2     9eb    f3a      8d6   
absorb   abstract absurd  abuse  access   accident  

a8d      33a      3bc     0dc    45c      44a 
account  accuse   achieve acid   acoustic acquire  

c4a      f6e      be5     00a    e7d      f8f 
across   act      action  actor  actress  actual


3.2 Then the hex value of these three characters is converted to a number, 
which is truncated by the mask 0x7ff (this number corresponds to the size of the big39 dictionary)

3.3 For each word of seed-phrase, a number is taken, the number of the word's position in the bip39 dictionary.

abandon  ability  able    about  above    absent 
1        2        3       4      5        6     

absorb   abstract absurd  abuse  access   accident  
7        8        9       10     11       12 

account  accuse   achieve acid   acoustic acquire  
13       14       15      16     17       18

19       20       21      22     23       24 

3.4 Using the XOR bit operation, the word number is added to the number 
obtained from the three letters hash512 and the resulting value 
(which is located within the bip39 dictionary) is the word number of the fake seed phrase,
each word of which is truncated to 4 letters

5. If you need to get the original seed phrase, 
then you need to enter the words (or numbers of their positions 
in bip39 dictionary) of the fake seed phrase, 
as well as the number, password, and email address (the same ones 
that were used to create the fake seed phrase) 
and click the "Unpack packed seed" button
