class Bip39EntropyGenerator(bit_len: Union[int, Bip39EntropyBitLen])

Bases: EntropyGenerator

BIP39 entropy generator class. It generates random entropy bytes with the specified length.

static IsValidEntropyBitLen(bit_len: Union[int, Bip39EntropyBitLen]) → bool

Get if the specified entropy bit length is valid.

Parameters:

bit_len (int or Bip39EntropyBitLen) – Entropy length in bits

Returns:

True if valid, false otherwise

Return type:

bool

static IsValidEntropyByteLen(byte_len: int) → bool

Get if the specified entropy byte length is valid.

Parameters:

byte_len (int) – Entropy length in bytes

Returns:

True if valid, false otherwise

Return type:

bool

m_bit_len: int
