    • The seed created by HMAC hashing the recovery mnemonic is the output of BIP39 and the input to BIP32 https://github.com/bitcoin/bips/blob/master/bip-0032.mediawiki

    • I created a mnemonics and it is hashed using pbdkf2 function and I got a root seed. So this root seed should be hashed again with HMAC-SHA512 to get the master key (Master private key and chain code). So for a HMAC-SAH512 we need a key and data, so in this case what should be the key? Data should be the root seed and what should I give as key in hmac function. I gave "Bitcoin Seed" as key and generated a hash, but it is not matching the output showed in https://iancoleman.io/bip39/ website
