Hindu keys in the HD structure of the portfolio: best practice

Ethereum determined hierarchical portfolios (HD) provide a safe way to preserve and manage private keys. A critical aspect of safety maintenance is the protection of the main private keys, more special in the structure of the HD portfolio. In this article, we will explore the best practices for the use of hardened keys in the HD portfolio.

Understanding Hindu keys

Harden keys are encrypted versions of Ethereum's normal private keys. Unlike normal keys, which can be easily restored by an attacker, unusual, without the key to decrystography, hardened keys require a separate and strong key to unlock them. This is especially important in the structure of the HD portfolio, in which more baby keys show the extended key on the main one.

General guidelines for Hindu keys

When building a HD portfolio structure with hardened keys, consider the following best practices:

• 
  Extended key chief : Make sure all the child's keys to the extended key to the teacher are also hardened.

2 Genilic keys that show children's keys can usually remain without construction.

• 
  Stranging layers : Divide the HD portfolio into layers:

* Main extended key: This is usually the highest key in the wallet and should always harden.

* Child keys: These are keys for children showing the extended basic key.

* Subchild of keys: they are even more specific, the baby's keys within one key.

• 
  Avoid hardened genille keys : As mentioned above, genille keys should usually not be left without coasts unless necessary.

Additional Considerations

When building an HD portfolio structure with hardened keys:

• 
  Regular maintenance : Periodically experience the keys to make sure they remain safe over time.

• 
  Return key
  
  
  
  : Rotate the keys regularly (for example every 12 months) to minimize the impact of the compromise or losing of keys.

Conclusion

Proper implementation of the hardened keys in the HD portfolio structure is crucial to maintaining safety and integrity of Ethereum private keys. Following these best practices, you can make sure that your keys remain protected and difficult to compromise. Remember to prioritize the basic maintenance and backup procedures to minimize potential risks.

Example for use:

Suppose we have an HD portfolio with an extended main button that is hardened. You also have baby keys pointing this extensive key. The following structure would be appropriate:

`

Master Extended Key (Hindu)

/

Child1

/

Child2

`

In this example, all the keys of the children are hardened (ie their private keys are encrypted and protected), while the extended key of the master remains without hardening.

Following these guidelines and best practices, you can effectively protect your private Ethereum keys in an HD portfolio structure.
