With this change coinb.in uses the same mechanism to generate seed from a passphrase like https://bip32.org: 50000 rounds of HMAC SHA-256 encryption.
The amount of rounds is configurable and the value
0results in the same mechanism as before for compatibility. The generated seed is also shown in WIF format, which is also withbitcoin-clicompatible. It is possible now to generate the same wallet usingbitcoin-cli sethdseed true <seed_wif>command in bitcoin core.To be really fully compatible with
bitcoin-cli, the fix in #228 pull request is also required.
