Fixed keys in HD Wallet Structure Structure: Best Practice
Ethereum’s hierarchical determined (HD) wallets provide a safe way to store and manage private keys. One of the critical aspects of safety maintenance is the protection of fundamental private keys, especially in the structure of the HD wallet tree. In this article, we will explore the best practices to use hardened keys within HD wallets.
Understanding the harden keys
The solidified keys are encrypted versions of regular Ethereum of private keys. Unlike regular keys, which the striker can easily recover without a key to deciphering, harden keys require a separate, strong unlock key. This is especially important in the structure of the Wallet Wallet tree, where more children’s keys indicate the main extended button.
General Guidelines for hardening keys
When constructing the structure of the HD wallet tree with hardy keys, consider the following best practices:
- Master Extended Key : Ensure that all children’s keys to the main extended key are also solidified.
- Parental keys to the child’s keys : usually the children’s keys should not be hardened unless absolutely necessary (eg in administrative or audit purposes). Parental keys, which refer to children’s keys, can usually remain uninformed.
- Layered Key Structure
: Divide the HD wallet into layers:
* The main extended key: this is usually the biggest key in your wallet and should always be hardened.
* Baby keys: These are children’s keys referring to the main extended button.
* Subhild keys: these are even more specific, children’s keys inside one children’s keys.
- Avoid hardening parental keys : As mentioned earlier, parental keys should usually remain unauthorized if necessary.
Additional considerations
When building a construction of an HD wallet with hardened keys:
- regular maintenance : periodically re -install keys to ensure that they remain safe over time.
- Kyles Rotation : Roll the keys regularly (eg every 12 months) to reduce the effect of compromise or the loss of the key.
- Back and recovery
: ensure you have a reliable spare plan, including a secondary storage mode for your HD wallet.
Conclusion
Proper implementation of hardening keys within the structure of the Wallet Wallet tree is crucial to maintaining the safety and integrity of your private keys to Ethereum. Following these best practices, you can ensure that your keys remain protected and difficult to compromise. Remember that you always set priority with key maintenance and backups to reduce potential risks.
Example uses the case:
Suppose you have an HD wallet with the main extended key, which is solidified. You also have children’s keys to refer to this main key. The next structure would be appropriate:
`
Main extended key (solidified)
/ \ \ \ \ \ \ \ \ It
Child11
/ \ \ \ \ \ \ \ \ It
Child22
`
In this example, all children’s keys are hardened (ie their private keys are encrypted and protected), while the master extended key remains unauthorized.
Following these guidelines and best practices, you can effectively protect your private keys to the Ethereum within the structure of the HD wallet.
