class Bip39MnemonicDecoder(lang: Optional[Bip39Languages] = None)

Bases: MnemonicDecoderBase

BIP39 mnemonic decoder class. It decodes a mnemonic phrase to bytes.

Decode(mnemonic: Union[str, Mnemonic]) → bytes

Decode a mnemonic phrase to bytes (no checksum).

Parameters:

mnemonic (str or Mnemonic object) – Mnemonic

Returns:

Decoded bytes (no checksum)

Return type:

bytes

Raises:

• MnemonicChecksumError – If checksum is not valid

• ValueError – If mnemonic is not valid

DecodeWithChecksum(mnemonic: Union[str, Mnemonic]) → bytes

Decode a mnemonic phrase to bytes (with checksum).

Parameters:

mnemonic (str or Mnemonic object) – Mnemonic

Returns:

Decoded bytes (with checksum)

Return type:

bytes

Raises:

• MnemonicChecksumError – If checksum is not valid

• ValueError – If mnemonic is not valid
