How do you store and protect your keys?

Applications based on blockchain technologies , as a guarantee of access, use, as a security and access measure, public and private keys which are stored in user wallets . These keys are essential, since they are the safeguard of correct access, that only we can manipulate the account, the keys issued by the wallet prevent third parties from fraudulently entering and eventually stealing our assets deposited there.

The importance of knowing how to keep our keys in a safe place, stored in a reliable way, whose access is private and easy to locate, is obviously deduced.

I store the passwords in my Gmail account, as it is, if you will, a storage cloud, it gives me the certainty that I will not lose it there. Unless I suffer from Alzheimer's in my old age, I will never forget my email access password. And since my email password is long and complex enough (27 characters, with alternate numbers, symbols and capital letters), I am sure of its inviolability.

I write the keys in a small notebook, kept in a place that only I can access.

Storing the passwords in a PDF document, to later compress that document, and put a password on it.

I usually associate my passwords with movies and everyday items that particularly attract me, so memory makes its cognitive association, retaining that password without the risk of forgetting it. After all, there is no more secure vault than our own brain.

What are the different types of private keys? (examples with screenshot)

Due to their characteristics, private keys are divided into:

• Private key: o private key is a set of alphanumeric characters using elliptic curves (ECC), composed in cryptographic language. This ensures that no password is the same, and that it is virtually impossible for any server to guess a key. It is through the asymmetric cryptographic process, where we obtain the public key , which will be like our public signature, visible in each transaction we carry out.

The private key will be our access key to the wallet . Only we have access to it.

• Mnemonic key: It is an identification key based on a series of words (representing an identification linked to a series of numbers), between 12 - 24 series. Every time a wallet is created, the system demands the creation of one of these keys, which serve as a backup in the event of loss of the private key and preservation of access to the wallet .
  This key, (created based on the BIP-39 protocol) like the private key, is unique; that is, the series of characters that a user receives will not be repeated in the password of another user.

In addition to this key, certain wallets require the creation of a seed phrase, as a means of second-degree authentication. this phrase, commonly a word, that prevents the situation in which a third party copies the mnemonic key and thus gains access to the user's account.

• Keystore File (JSON): O Keystore File Key , Here the private key is stored in a Java Script file (a programming data processing text format), thus generating a password that encrypts the Keystore file created, which Unlike the private key, we can choose; working as a double method of protecting our private key.

How do you store the key? (demonstrate with examples)

The password, (as it is the acronym of three musical groups), I store it in the safest place of all: in the hard disk of my memory (I have good retention, I think).

Regarding the mnemonic key , I first wrote them down in a Word document (I am wary of leaving data, such as passwords, in a note book ). Once the document is created, I auto-send it to my email account. I have also compressed the document under RAR format, with its respective password. Besides, I have left it written on paper, kept a trustworthy drawer.
