If you have been surfing the web since its inception, you know how important it is to have an effective password. A password like "123456" would be cracked in seconds, without any difficulty.
These are the password cracking times and you can see that by entering random characters and symbols it becomes more and more difficult to find the password.
There are online sites that allow you to calculate how secure your password is () and how long it takes to crack it (Password Strength Checker
It is also possible to generate more secure passwords using dice and thus exploiting the concept of "entropy". Entropy in a physical system is the degree of disorder. In computer science, as entropy increases, the amount of information decreases. Generating a password with entropy (completely random) is very simple:
1) Download the dictionary (word list) Diceware
2) Choose how many words you would like for your password
3) Roll some dice. For each word, roll the dice 5 times. If you have chosen 6 words you will have to roll the dice 30 times. For each word you will get 5 numbers (then check in the dictionary which word they correspond to)
4) Use symbols like .!,$? to make your password more complex
GENERATE SEED FOR BITCOIN WITH ENTROPY
The first issue you need to pay attention to is the number of words that will make up your seed. There are 12 or 24 word seeds. Word number 12 and 24 is a check word called a "checksum".
First we download Ian Coleman's tool which we will then use offline:Ian Coleman (BIP39)
What we need are:
-physical coin (heads/tails)
-4 dice (with 6 sides)
If I toss the coin and get heads I will have "h", then I roll the 4 dice and read from left to right (or vice versa) the 4 numbers that come out, then I go to look for them in the table (Diceware Entropy BIP39) which contains 2048 words (raised to 12 they show me the possible combinations). I will get for each word for example h2345 or t1425. I repeat this procedure for the 12 words. Then I insert the 12 words found in Coleman's tool (offline), the 12th must be changed (because it is a checksum, ie a control word). For example, if my 12th word is "Black" (image below), I will manually enter the 16 words above until I find the right one (I always use Ian Coleman's tool, entering the first 11, then the 12th by trial and error).
Once the seed is reported right, I can put it in my hardware wallet or software (like Electrum) with 12 words (128 bit). If it is not reported as valid, press on "options" and tick the box on beep39.
If the seed has 24 words (256 bit), I can use the dice and the coin by finding the 23 words and then the 24th using this checksum finding tool: Bip39checksum
For a PaperWallet you can use:
For the bip85 (seed also at 18 and 24 words):
Another procedure exploits the entropy of the binary numbers, assigning the 0 to the numbers 1, 3 and 5 and the binary 1 to the numbers 2, 4 and 6. Then I carry out the calculation following this scheme (I carry it out 23 times for the 23 words of the my seed, for the 24th the same argument applies before):
In this case I use this BIP39 dictionary which is different in syntax (it doesn't contain "h" or "t" but the words are always the same).
The seed must then be finalized/imported into a software/hardware wallet, remember that it is always important to carry out these operations offline. Once imported you can connect the device online. These are just a few examples. You can use any method you want. The most important thing is to do everything offline!
