它是怎么工作的？

为了从记忆中创建iota种子，我们使用iota kerl函数和 用作密码和字符串的助记符句子（utf-8nfkd） “助记符”+密码短语（同样是utf-8nfkd）用作盐。

为了得到一个有效的tryte散列，我们浓缩了salt和助记语句，并且 通过from_string函数加载到iota.Hash中。from_string 将utf-8nfkd编码为字节，然后将字节转换为iota散列。

使用每个散列，然后使用散列trits和kerl吸收和挤压：

trits=[]sponge=iota.crypto.kerl.Kerl()forwordinmnemonic:hash=iota.Hash.from_string(f'mnemonic{passphrase}{word}')hash_trits=hash.as_trits()k=iota.crypto.kerl.Kerl()k.absorb(hash_trits)k.squeeze(hash_trits)sponge.absorb(hash_trits)sponge.squeeze(trits)returniota.Hash.from_trits(trits)
