In this post, we consider a simple way to create/restore and manage virtual offline crypto wallets and seeds with public DPGs.
Step 1. Select easy memorable key, date and salt. For example, key=”MyName”, date=2026/1/1 salt=”book111”. Using a public DPG, generate 20 output strings with the key and date.
Step 2. Go to this URL https://www.dynpass.online/tools/bip39/offline/12w.html
Disconnect from internet!!!
Create a passphrase using an easy to remember formula. For example, we use this formula: passphrase=string 1+salt+string 5, where string 1 is the first string in the output of the public DPG https://www.dynpass.online/ and string 5 is the fifth string in the output of the public DPG.
passphrase=”ndn_{5z$_dGqbyEW@sZ_book111NXVF#=dPrxZ6b7[J37oA”
Enter this passphrase into the corresponding field and click on the “Generate 12 Words” button.
You will see your 12 words at the bottom. For the reason that your device is offline, hackers can not access your device via internet, now. You can import this 12 words list as a seed phrase to create a crypto hardware/software wallet with a set of blockchain addresses and private keys to manage your crypto. You can use your private keys to send crypto and your blockchain addresses to receive crypto. After sending crypto, you can completely delete/remove/reset your hardware/software crypto wallets and the corresponding seed phrases. When you close your web browser, assuming the web browser does not save data to caches or any other place, your seed phrase disappear from the real world. For the reason that your seed phrase does not exist in the real world, it can not be hacked, stolen, broken, lost, confiscated, forgotten, etc. When you need your seed phrases and private keys again to send crypto, you use the same procedure to recover your seed phrases and private keys. With public DPGs it is easy to manage up to 20 virtual offline crypto wallets and seeds. With private DPGs it is easy to manage up to 100 virtual offline crypto wallets and seeds.
P.S. 1. If you want to have a local personal copy of this seed phrase generator/converter then you can save it as a html page on your local computing device/USB drive/SD card/etc. and use it offline, anytime.
2. If you need a 24 words list/seed phrase then use this generator/converter https://www.dynpass.online/tools/bip39/offline/24w.html
3. If you can not access the URLs above then you can use these backup URLs:

4. Virtual offline crypto wallets are the most secure crypto wallets, contrary to the popular false myth that hardware wallets are the most secure crypto wallets.
5. Before usage of virtual wallets, check that the generated crypto addresses do not have any historical transactions. You can use any online crypto address explorer, like:
https://www.blockchain.com/en/explorer
https://www.blockexplorer.com/
6. Take into account, that some companies claim that their AI agents use virtual wallets, but those wallets are not virtual, they are software wallets with programmable interfaces. They use random number generators for keys generation, which may have the “low entropy problem”. Virtual wallets use dynamical generators, which do not have such problem, with private DPGs.
