Address

用于转换公共地址和公共密钥的工具。

从**@kaiachain/ethers-ext软件包中导入getCompressedPublicKey**。

从 "账户 "对象中，您可以使用 "address_from_private_key "获取公共地址，或使用 "compressed_key "获取压缩公共密钥。

根据未压缩公钥的 x 和 y 坐标，可以使用 compressed_key_from_xy 和 compressed_key_and_address_from_xy 获取公钥和地址。

from eth_account import Account

from web3py_ext.klaytn_account.utils import compressed_key_from_xy, address_from_private_key, compressed_key, \

compressed_key_and_address_from_xy

def main():

private_key=Account.from_key("0x0e4ca6d38096ad99324de0dde108587e5d7c600165ae4cd6c2462c597458c2b8")

print("Public key from private key",address_from_private_key(private_key))

print("Compress key from private key"、compressed_key(private_key))

x = "0xdc9dccbd788c00fa98f7f4082f2f714e799bc0c29d63f04d48b54fe6250453cd"

y = "0xaf06ca34ae8714cf3dae06bacdb78c7c2d4054bd38961d40853cd5f15955da79"

print("Compress public key from x、y", compressed_key_from_xy(x, y))

print("Compress public key and address from x,y", compressed_key_and_address_from_xy(x, y))
