class Bip38NoEcEncrypter

Bases: object

BIP38 encrypter class. It encrypts a private key using the algorithm specified in BIP38 without EC multiplication.

static Encrypt(priv_key: Union[bytes, IPrivateKey], passphrase: str, pub_key_mode: P2PKHPubKeyModes) → str

Encrypt the specified private key.

Parameters:

• priv_key (bytes or IPrivateKey) – Private key bytes or object

• passphrase (str) – Passphrase

• pub_key_mode (Bip38PubKeyModes) – Public key mode

Returns:

Encrypted private key

Return type:

str

Raises:

• TypeError – If the private key is not a Secp256k1PrivateKey

• ValueError – If the private key bytes are not valid

class Bip38NoEcDecrypter

Bases: object

BIP38 decrypter class. It decrypts a private key using the algorithm specified in BIP38 without EC multiplication.

static Decrypt(priv_key_enc: str, passphrase: str) → Tuple[bytes, P2PKHPubKeyModes]

Decrypt the specified private key.

Parameters:

• priv_key_enc (str) – Encrypted private key bytes

• passphrase (str) – Passphrase

Returns:

Decrypted private key (index 0), public key mode (index 1)

Return type:

tuple[bytes, Bip38PubKeyModes]

Raises:

• Base58ChecksumError – If base58 checksum is not valid

• ValueError – If the encrypted key is not valid
