@ -96,6 +96,16 @@ Copay also implements [BIP32](https://github.com/bitcoin/bips/blob/master/bip-00
For more information regarding how addresses are generated using this procedure, see: [Structure for Deterministic P2SH Multisignature Wallets](https://github.com/bitcoin/bips/blob/master/bip-0045.mediawiki).
## Backup format
Copay encrypts the backup with the Stanford JS Cryto Library (https://crypto.stanford.edu/sjcl/). To extract the private keys you can use https://bitwiseshiftleft.github.io/sjcl/demo/ , copy the backup to 'ciphertext' and enter your password. The resulting JSON will have a key named: `xPrivKey`, that is the extended private key of your wallet. That information is enought to sign any transaction of your wallet, so be careful handling it.
Also in the backup there is also key `publicKeyRing`. That hold the extended public keys of the Copayers. Using a tool like [Bitcore PlayGround](http://bitcore.io/playground/#/multisig), and following [BIP45](https://github.com/bitcoin/bips/blob/master/bip-0045.mediawiki) it is possible to generate all wallet address. Note that addresses generated at BWS use the 'shared cosigner index' (2147483647) so Copay address index look like:
`m/45'/2147483647/0/x` for main addresses and
`m/45'/2147483647/1/y` for change addresses, where `x` and `y` and integers starting from `0`. To generate the wallet addresses it is also needed to specify the required number of signatures. That is present in the backup also with the key `n`.
## Bitcore Wallet Service
Copay depends on [Bitcore Wallet Service](https://github.com/bitpay/bitcore-wallet-service) (BWS) for blockchain information, networking and copayer synchronization. A BWS instance can be setup and operational within minutes or you can use a public instance like `https://bws.bitpay.com`. Switching between BWS instances is very simple and can be done with a click from within Copay. BWS also allows Copay to interoperate with others wallet like [Bitcore Wallet CLI] (https://github.com/bitpay/bitcore-wallet).
