09 Feb Ethereum: Practical way to split a bip39 seed into a 2 out of 3 factor auth?
PROVIDE YOUR SEMAN ETHEREUM with the help factorotentification
As an Ethereum, you know about the importance of the arrangement of your semen in partly and immobilized. The case may be interstate as you cut your mammonic code on the more small section, the factory as “authentic factor”, which calls you to restore your cops. See three parts. This underwear is frequently referred to as the authentic factor “2 from 3”.
In this state, we will be able to do in the practical deposit of this immobility and efficient method of management of the ethereum seeds.
Ponimania of mammonic codes and factor utter
The mneumonic code is the postponant of the words, which introduce the lyric key to the Ethereum. Except he is generated with the use of phrases or the presentations of 12 words that are bound by your liner information, this as your name, the date of the Christmas or the password. The mammonic code serves the “seed” for your ethereum address.
Factor authentification – this method of breaking the mneumonic code on a more small section called “factor”. These fats are used for the restoration of a partial key from the reserve copy of paper. The authentification of the factor of the 2nd-3 factor indicates that you need two of these factors for the restoration of your Koshelka, and one of them can be a reserve copy of the paper.
Breaking your mammonic code on the factor
To cut off your mammonic code on a three-faculty of the Standard of the Ethereum Factor (EIP-1559), the powered act:
1.
- Submit the interface for Mnemonic Code : Write the walls in the tongue, which is subjected to solidno, which sets out the code of mneumonic right.
That’s the main priemer of that, as you can realize this:
`
Pragma Polidy ^0.8,0;
CONTRACT {
Public mnemonics (Address => String);
Displaymnemonic (String Memory _Mnemonic) Function Observatory Vyazvarat (String Memory, String Memory) {
for (uint256 I = 0; I <12; I ++) {
String Memory TempmneMinics = _Mnemonic;
IF (I == 6 && I == 9 || I == 12) {
Tempmnemonics += “Your Name”;
}
mnemonics [msg.sender] = tempmnemonics;
}
}
Function Gettwofactors (String Memory _Mnemonic, String Memory _input) Oblast Vytroza (String Memory) {String Memory)
uint256 I = 0;
While (I <2 && I <12) {
IF (Mnemonics [_Mnemonic] .Contains (_input)) {
return mnemonics [_mnemonic] [i] + “Your name”;
}
I ++;
}
Recruit (“”, “”);
}
GETONEFACTOR (Address _Address) Function APPLOOK APPLOOD (String Memory)
for (uint256 I = 0; I <12; I ++) {
IF (Mnemonics [_Address] .Contains (mnemonics [msg.sender])) {
return mnemonics [_address] [i];
}
}
Return “” “;
}
}
`
Reduction Your Koshka Trezor
To bother your points, use two factors, downstairs this shagi:
1.
- Insert the Odin factor from the reservoir of paper : Use the first factor to interfere with the pots and get access to your own medium.
After that, as you brought up your pot, use the three factor (from the outward code of the mammary), in order to spoil a new mamming or in the most usefulness for the more powerlessness.
conclusion
The section of your mneumonic code on the factor provides an add -on the diminishing of the Ethereum semen. The trace of the EIP-1559 standard and the Polish interface for Mnemonic Code, you can make this practical method for the provision of your semen.
