Hello friends today I'll be doing my homework on the beginners' fixed task 9. I have chosen to answer question 1, which says;

How do you store/secure your keys? What are the different forms of Private Key(Examples/Screenshot)? Download & Install TronLink Wallet(Android/iOS/Extension)? How do you store the key(Hint- write it down on a notepad, demonstrate it with examples)? Which form of the key are you comfortable with to handle your TronLink Wallet? Include Screenshots & hide/blur the sensitive information.

How do you store/secure your keys?

Sometimes we wonder where and how to store our blockchain wallet keys. It is important and good to store your wallet keys in a secure and trusted place. And I believe the best way to store and secure a digital wallet key is by writing. Write it down a paper, and put it in a trusted and secure place, it is adviced you do not write it on one particular paper alone, write it on separate papers.
In the case of the Keystore file (JSON file), which only works when mixer with a password, you're not to disclose or let any other person find out the password, and also try to write the password down because the human memory cannot be trusted.
Please note that it is not ideal to save digital keys on a cloud service or an email. It is also not adviced to take screenshots of the keys and store it as an image in your mobile/pc because you may no be the only one who has access to images on your mobile/pc.

What are the different forms of Private Key(Examples/Screenshot)?

The private key for a digital wallet can come in different forms, which are ;
•Private Keys (Alphanumeric character)
•Mnemonic Key
•Keystore File (JSON file)

1. Private Key(alphanumeric):

The private key is a string which contains letters and numbers. It is gotten/downloaded immediately after creating a blockchain wallet. This kind of key is not readable due to its alphanumeric nature, it helps users protect whatever fund or coins they have in their wallet.

2. Mnemonic Key:

In literal terms a mnemonic, otherwise called memory aid, is something which that helps a person easily remember something. It consists of phrases properly arranged in a pattern. It can be a phrase of numbers or words.
The mnemonic key, which is also called "Seed" is a key consisting of 12 or 24 words. Unlike others, it is readable because the words which makes up an mnemonic key, consists of the random words which is already familiar to us. It is used to unlock a wallet, generate and restore wallet addresses.

3. Key Store File (JSON file):

The third form of a private key is the Keystore File. In order for this key to work, it is backed up or combined with a password made from an created by the user. TheKeystore/JSON file contains an encrypted version of the private key, this means that the private key will be encoded into a string of characters, which sometimes makes no sense. For an example, the word *table", If it is encrypted with a 5-character difference down the English alphabets/letters, it would become 'xefpi'. A person would never know what xefpi meant, unless it is explained.

During the registration process, I carefully wrote down my mnemonic keyand the password I used on a paper and put it in a secure and trusted place. Below is a picture of the paper I wrote it on.

Which form of the key are you comfortable with to handle your TronLink Wallet?

I am comfortable with the mnemonic key and I love it. It is so easy to write down and understand, because the phrases are already familiar. Below is a screenshot of my mnemonic key

It consists of 12 phrases. I have hidden some in the picture for security reasons, because it is a personal and private key. It should not be made public.
