substrate_keys

Module for Substrate keys handling.

class SubstratePublicKey(pub_key: IPublicKey, coin_conf: SubstrateCoinConf)

Bases: object

Substrate public key class.

classmethod FromBytesOrKeyObject(pub_key: Union[bytes, IPublicKey], coin_conf: SubstrateCoinConf) → SubstratePublicKey

Get the public key from key bytes or object.

Parameters:

• pub_key (bytes or IPublicKey) – Public key

• coin_conf (SubstrateCoinConf object) – SubstrateCoinConf object

Returns:

SubstratePublicKey object

Return type:

SubstratePublicKey object

Raises:

SubstrateKeyError – If the key constructed from the bytes is not valid

classmethod FromBytes(key_bytes: bytes, coin_conf: SubstrateCoinConf) → SubstratePublicKey

Create from bytes.

Parameters:

• key_bytes (bytes) – Key bytes

• coin_conf (SubstrateCoinConf object) – SubstrateCoinConf object

Raises:

SubstrateKeyError – If the key constructed from the bytes is not valid

m_pub_key: IPublicKey

m_coin_conf: SubstrateCoinConf

KeyObject() → IPublicKey

Return the key object.

Returns:

Key object

Return type:

IPublicKey object

RawCompressed() → DataBytes

Return raw compressed public key.

Returns:

DataBytes object

Return type:

RawUncompressed() → DataBytes

Return raw uncompressed public key.

Returns:

DataBytes object

Return type:

DataBytes object

ToAddress() → str

Return the address correspondent to the public key.

Returns:

Address string

Return type:

str

class SubstratePrivateKey(priv_key: IPrivateKey, coin_conf: SubstrateCoinConf)

Bases: object
