beembase.account module¶
-
class
beembase.account.
Address
(*args, **kwargs)¶ Bases:
graphenebase.account.Address
Address class
This class serves as an address representation for Public Keys.
Parameters: - address (str) – Base58 encoded address (defaults to
None
) - pubkey (str) – Base58 encoded pubkey (defaults to
None
) - prefix (str) – Network prefix (defaults to
STM
)
Example:
Address("GPHFN9r6VYzBK8EKtMewfNbfiGCr56pHDBFi")
- address (str) – Base58 encoded address (defaults to
-
class
beembase.account.
BrainKey
(*args, **kwargs)¶ Bases:
graphenebase.account.BrainKey
Brainkey implementation similar to the graphene-ui web-wallet.
Parameters: - brainkey (str) – Brain Key
- sequence (int) – Sequence number for consecutive keys
Keys in Graphene are derived from a seed brain key which is a string of 16 words out of a predefined dictionary with 49744 words. It is a simple single-chain key derivation scheme that is not compatible with BIP44 but easy to use.
Given the brain key, a private key is derived as:
privkey = SHA256(SHA512(brainkey + " " + sequence))
Incrementing the sequence number yields a new key that can be regenerated given the brain key.

class
beembase.account.
PasswordKey
(*args, **kwargs)¶ Bases:
graphenebase.account.PasswordKey
This class derives a private key given the account name, the role and a password. It leverages the technology of Brainkeys and allows people to have a secure private key by providing a passphrase only.

class
beembase.account.
PrivateKey
(*args, **kwargs)¶ Bases:
graphenebase.account.PrivateKey
Derives the compressed and uncompressed public keys and constructs two instances of
PublicKey
:Parameters: - wif (str) – Base58check-encoded wif key
- prefix (str) – Network prefix (defaults to
STM
)
Example::
PrivateKey("5HqUkGuo62BfcJU5vNhTXKJRXuUi9QSE6jp8C3uBJ2BVHtB8WSd")
Compressed vs. Uncompressed:
PrivateKey("w-i-f").pubkey
:- Instance of
PublicKey
using compressed key.
PrivateKey("w-i-f").pubkey.address
:- Instance of
Address
using compressed key.
PrivateKey("w-i-f").uncompressed
:- Instance of
PublicKey
using uncompressed key.
PrivateKey("w-i-f").uncompressed.address
:- Instance of
Address
using uncompressed key.

class
beembase.account.
PublicKey
(*args, **kwargs)¶ Bases:
graphenebase.account.PublicKey
This class deals with Public Keys and inherits
Address
.Parameters: - pk (str) – Base58 encoded public key
- prefix (str) – Network prefix (defaults to
STM
)
Example::
PublicKey("GPH6UtYWWs3rkZGV8JA86qrgkG6tyFksgECefKE1MiH4HkLD8PFGL")
Note
By default, graphene-based networks deal with compressed public keys. If an uncompressed key is required, the method
unCompressed
can be used:PublicKey("xxxxx").unCompressed()
