sign_hash gives different from web3.sign last byte of the result signature

[dtaipov]

Piece of code to prepare hash for KeyChain

const keyname = 'test1@76de427d42c38be4';
const message = '12345';
const prefix = "\x19Ethereum Signed Message:\n" + message.length;
const messageHash = web3.utils.sha3(prefix + message).substr(2);
const result = await keychain.signHash(messageHash, keyname);

Example messageHash: 0xffdc74e2c931e2639c9642e818d04d9e13ce814360876d99c8738521cb0502bf

KeyChain result: f9d5c73b846d85b13ca588338a98002babaf5581c3bcea87b71cc811ee31d85b58cc4ed45bcb5a4c902f9b2b246c3caefa33138e97dbc4fd446c4b7d0df65bfc01

Web3 const privateKey = '0xb3d3427eea7867c243baaf2f4c67a9551eea2ea96556acfb0051dffa18d182d4'; web3.eth.accounts.sign('12345', privateKey) result:

{ message: '12345',
  messageHash:
   '0xffdc74e2c931e2639c9642e818d04d9e13ce814360876d99c8738521cb0502bf',
  v: '0x1c',
  r: '0xf9d5c73b846d85b13ca588338a98002babaf5581c3bcea87b71cc811ee31d85b',
  s: '0x58cc4ed45bcb5a4c902f9b2b246c3caefa33138e97dbc4fd446c4b7d0df65bfc',
  signature: '0xf9d5c73b846d85b13ca588338a98002babaf5581c3bcea87b71cc811ee31d85b58cc4ed45bcb5a4c902f9b2b246c3caefa33138e97dbc4fd446c4b7d0df65bfc1c' }

Web3 result: '0xf9d5c73b846d85b13ca588338a98002babaf5581c3bcea87b71cc811ee31d85b58cc4ed45bcb5a4c902f9b2b246c3caefa33138e97dbc4fd446c4b7d0df65bfc1c'

The last byte in signature is different What can be done to make the last bytes the same?
