Due the increasing use of online-seed-generators with hacking consequenses I want to advise against the online-seed-generators.
manual - How to create a safe seed for my IOTA wallet:
Step 1:
Search for 20 words about your private life. For example hobbies, family, password, memorys, pets...
(overall these words should have 80 letters together)
Step 2:
Write down these words in CAPSlock. All in a row (with spaces between them).
Step 3:
Now think about a pattern to modify these words.
For example: change all A´s to U´s. Also the first letter of each world would be replaced with the first letter of the following word. The same with the last letter of each word. After that you could change all O´s to M´s and change every third letter of each word to a K. And so on...
Step 4:
remove the spaces between the single words.
Step 5:
Add the number 9 on any pleace in your seed.
Step 6:
Check again if the seed has 80 letters and one 9 in it. (in total 81 symbols)
Step 7:
Took a piece of paper and a documentary pen wich you can also read in many years. (No lead pencil)
Write down the whole seed. Check 2 or 3 times if every letter you wrote is correct.
Step 8:
Now you have a very secure seed and you can start to send your IOTA to your wallet.
I think this seed is 100 times more secure than any random keyboard hit or a online-seed-generator.
Finished!
It´s easy to reconstruct a random hit on the keyboard. If you think about that every day thousand of people are creating seeds the probability that someone else generates the same seed by hitting the keyboard like u is very high.
About the seed generators: The whole generator is located on a server. We don´t know if this server would safe our generated seed. So this is absolutely unsafe!!!
I hope that this post can help you to create a very safe seed!
