地址

用於轉換公共地址和公共密鑰的工具。

從 @kaiachain/web3js-ext 軟件包導入 getCompressedPublicKey

要將公鑰從{x, y}格式壓縮為十六進制，請使用 getCompressedPublicKey 並將公鑰對象作為參數

否則，如果要壓縮未壓縮十六進制的公鑰**，請使用 getCompressedPublicKey 並將未壓縮公鑰作為參數

addressUtils.js

const { getCompressedPublicKey } = require('@kaiachain/web3js-ext')

async function main() {

const publicKeyObject = {

x: '0xdc9dccbd788c00fa98f7f4082f2f714e799bc0c29d63f04d48b54fe6250453cd',

y: '0xaf06ca34ae8714cf3dae06bacdb78c7c2d4054bd38961d40853cd5f15955da79',

}

console.log(

'pubkey from { x, y } object =',

getCompressedPublicKey(publicKeyObject)

)

const uncompressedPublicKeyString =

'0x04dc9dccbd788c00fa98f7f4082f2f714e799bc0c29d63f04d48b54fe6250453cdaf06ca34ae8714cf3dae06bacdb78c7c2d4054bd38961d40853cd5f15955da79'

console.log(

'pubkey from uncompressed format =',

getCompressedPublicKey(uncompressedPublicKeyString)

)

}

main()

output
