Method Detail

calculateSeed

public byte[] calculateSeed(java.util.Collection<? extends java.lang.CharSequence> mnemonic,
                            java.lang.String passphrase)

Calculate the seed given a mnemonic and corresponding passphrase. The phrase is not checked for validity here, for that use a MnemonicValidator.

The purpose of this method is to avoid constructing a mnemonic String if you have gathered a list of words from the user and also to avoid having to normalize it, all words in the WordList are normalized instead.

Due to normalization, the passphrase still needs to be String, and not CharSequence, this is an open issue: https://github.com/NovaCrypto/BIP39/issues/7

Parameters:

mnemonic - The memorable list of words, ideally selected from the word list that was supplied while creating this object.

passphrase - An optional passphrase, use "" if not required

Returns:

a seed for HD wallet generation
