signMessage

功能

将 message 根据 Everpay 实例创建时，传递的 account, ethConnectedSigner, arJWK, isSmartAccount 参数进行签名

参数

everpay.signMessage(message: string, smartAccountDirectly?: boolean): Promise<SignMessageResult>

危险

• smartAccountDirectly 可不传递，默认为 false
• smartAccountDirectly 参数仅对邮箱账户的签名有效
• 当为邮箱账户时，!!smartAccountDirectly 为 true
  • 会使用 webauthn 直接签名 message
  • message 长度必须 >= 96
  • 返回结果中的 message 字段与原 message 一致
• 当为邮箱账户时，!!smartAccountDirectly 为 false
  • everpay-js 内部会先通过 hashMessage 对 message 进行一层 hash 处理后，再使用 webauthn 签名
  • message 没有长度限制
  • 返回结果中的 message 字段为 hashMessage(message) 后的 hex string

返回

export interface SignMessageResult {
  message: string
  sig: string
}

示例

EVM 签名示例

describe('signMessage for EVM', () => {
  test('signMessage EVM should be OK', async () => {
    const message = 'verify'
    const signResult = await everpayEVM.signMessage(message)
    expect(signResult.message).toBe(message)
    return await everpayEVM.verifyMessage({
      type: 'sign',
      message,
      account: ethWalletHasUSDT.address,
      sig: signResult.sig
    }).then(result => {
      expect(result.public).toBeTruthy()
      expect(result.publicId.toLowerCase()).toBe(ethWalletHasUSDT.address.toLowerCase())
    })
  })
})

Arweave 签名示例

describe('signMessage for Arweave', () => {
  test('signMessage for Arweave should be OK', async () => {
    const account = arWallet1.address
    const message = 'verify'
    const signResult = await everpayAR.signMessage(message)
    expect(signResult.message).toBe(message)
    return await everpayAR.verifyMessage({
      type: 'sign',
      message,
      account,
      sig: signResult.sig
    }).then(result => {
      expect(result.public).toBeTruthy()
      expect(result.publicId.toLowerCase()).toBe(account.toLowerCase())
    })
  })
})

邮箱账户签名示例

危险

因浏览器窗口安全弹出限制，请勿将 smartAccountAuth 接口与 signMessage 接口在同一个函数中调用，必须要由不同的事件函数触发。以下仅为示例

const authResult = await new Everpay().smartAccountAuth()
const everpaySmartAccount = new Everpay({
  account: authResult.account,
  isSmartAccount: true
})
const signResult = await everpaySmartAccount.signMessage('Hello World')
