Hey @tanzeelrana !

The passphrase is something different from what you may think immediately (@akegalj , @Martoon-00 , this is yet another testament that our current API is confusing). A passphrase is simply an (optional) extra password you specify when creating a wallet which will protect your private keys when spending funds. It is not the backup phrase, which is instead a 12-words mnemonic as the one you tried to post (look that you will still need to pass a 12-word mnemonic as part of the bpToList field, that in your example is simply set to the ["string"] array.

In particular, if you want to specify a passphrase (think of it as a spending password needed when generating a new address or spending funds) there are rules you need to abide to: it must be exactly 32-chars long and be encoded in base-16. You can use a tool like this one to play around.

@adinapoli-iohk

lets see if i clearly understood this. so the 12 word phrase needs to be converted into a single 32-chars long and be encoded in base-16 string and then be passed ?

[tanzeelrana]

Aha !! sweet got it !! :)

I have one more question. How do I generate a 12 word phrase that has not been used previously ???

[akegalj]

@tanzeelrana You can use some od generic tools for generatong bip39 12 word phrases like https://iancoleman.io/bip39/ (most of popular languages have this implemented)

Chances of collision are very minimal https://www.google.hr/amp/s/amp.reddit.com/r/ledgerwallet/comments/6cjvam/probability_of_seed_phrase_collisionbrute_forcing/

[alvinoktavbitcoin]

hi I don't really understand about the words that I need to enter, can you please tell me the steps more clearly ? I really hope

[adinapoli-iohk]

@alvinoktavbitcoin As @akegalj said, you can simply go to a website like https://iancoleman.io/bip39/ and use their web interface to generate a 12-words mnemonic password which you can use to initialise an HD wallet. Bear in mind if you lose this password you won't be able to restore your wallet anymore, so be careful 😉

[alvinoktavbitcoin]

yes , I have generate 12 words, now what I should I do with that 12 words ? I want to use API : https://cardanodocs.com/technical/wallet/api/#/ , but its need me to enter a passphrase that base 16-code

@alvinoktavbitcoin how are u connecting to the cardano-sl ? are you able to connect to it externally ? like is it hosted on a cloud server ? or are u doing everything locally ?

[afzydev]

@tanzeelrana

Please tell me how to run generate new address api. Thanks

[sunujacob]

I generate 12 random words using bip39 ? What should I do next? are there tools to generate passphrase that must be exactly 32-chars long and be encoded in base-16. ?

[sunujacob]

Is below api call correct? curl -k --request POST \ --url https://127.0.0.1:8090/api/wallets/new \ --header 'content-type: application/json' \ --data '{ "cwInitMeta": { "cwName": "My lovely wallet", "cwAssurance": "CWANormal", "cwUnit": 0 }, "cwBackupPhrase": { "bpToList": ["squirrel","material","silly","twice","direct","slush","pistol","razor","become","junk","kingdom","flee"] } }'

[Martoon-00]

Yes, it seems correct.

Mnemonics should be generated according to bip39, right.

Passphrase is optional; to make it complaint with Daedalus you need to first evaluate its blake2b hash, getting 32-length string, then encode to base16 before making request. See https://goo.gl/2uopZx (this process may be simplified with soon release of new version of wallet backend API)

@tanzeelrana @adinapoli-iohk Hi,friend!Could you paste your curl command about creating new wallets with passphrase and creating new addresses?I am really confused about the api docs! And which version api are u using?I tried the v1,but it didn't work,how about u?
