Generate Keypair

The :pyKeypair <stellar_sdk.keypair.Keypair> object represents a key pair used to sign transactions in a Stellar network. The :pyKeypair <stellar_sdk.keypair.Keypair> object can contain both a public and a private key, or only a public key.

If a :pyKeypair <stellar_sdk.keypair.Keypair> object does not contain a private key it can't be used to sign transactions. The most convenient method of creating a new keypair is by passing the account's secret seed:

from stellar_sdk import Keypair

secret = "SBK2VIYYSVG76E7VC3QHYARNFLY2EAQXDHRC7BMXBBGIFG74ARPRMNQM"
keypair = Keypair.from_secret(secret)

# GDHMW6QZOL73SHKG2JA3YHXFDHM46SS5ZRWEYF5BCYHX2C5TVO6KZBYL
public_key = keypair.public_key

can_sign = keypair.can_sign()  # True

You can create a keypair from public key, but its function is limited:

from stellar_sdk import Keypair

public_key = "GDHMW6QZOL73SHKG2JA3YHXFDHM46SS5ZRWEYF5BCYHX2C5TVO6KZBYL"
keypair = Keypair.from_public_key(public_key)
can_sign = keypair.can_sign()  # False

You can also create a randomly generated keypair:

from stellar_sdk import Keypair

keypair = Keypair.random()
print("Public Key: " + keypair.public_key)
print("Secret Seed: " + keypair.secret)
