签名

将签名从对象转换为元组格式，压缩签名。

从 @kaiachain/web3js-ext 包中导入 getSignatureTuple

要将公钥从{r, s, v}格式压缩为元组格式，请使用 getSignatureTuple 并将signature object作为参数

要将公钥从紧凑的 65 字节格式压缩成元组，请使用 getSignatureTuple 并将compact signature作为参数

signatureUtils.js


const { getSignatureTuple } = require('@kaiachain/web3js-ext')
async function main() {
  console.log(
    'signature from { v, r, s } object =',
    getSignatureTuple({
      v: 27,
      r: '0x66809fb130a6ea4ae4e823baa92573a5f1bfb4e88e64048aecfb18a2b4012b99',
      s: '0x75c2c3e5f7b0a182c767137c488649cd5104a5e747371fd922d618e328e5c508',
    })
  )
  console.log(
    'signature from compact 65 bytes =',
    getSignatureTuple(
      '0x66809fb130a6ea4ae4e823baa92573a5f1bfb4e88e64048aecfb18a2b4012b9975c2c3e5f7b0a182c767137c488649cd5104a5e747371fd922d618e328e5c5081b'
    )
  )
