Splits bitstring b into n-bit chunks.

Calculates CS for given ENT. Returns a tuple consisting of the checksum and its bit size.

Decodes unsigned integer from a binary. Bitstrings are left-padded.

Converts English mnemonic to its binary entropy. Validates the provided number of words, their existence in English wordlist and finally, the checksum.

If hex: true option is provided, the result is hex-encoded.

Generates random English mnemonic. Optional entropy length (strength) argument can be provided; defaults to 256 bits.

Retrieves index for an English word. Non-English wordlists are not implemented yet.

Generates English mnemonic for pre-existing entropy (obtained from elsehwere).

Left pads a bitstring with zeros.

Derives a hex-encoded PBKDF2 seed from mnemonic. Optional passhprase can be provided in the second argument.

Does not validate any mnemonic properties.

Returns a list of 11-bit word indices for given ENT_CS.

Retrieves English word by index. Non-English wordlists are not implemented yet.
