you cant needs private key and is in his server.
to encrypt and decrypt needs script like this:

const { generateKeyPair, CompactEncrypt, compactDecrypt } = require('jose');

const { publicKey, privateKey } = await generateKeyPair('ECDH-ES', { crv: 'P-256' })

  const payload = {
    mensaje: 'Here info you needs encrypt.this is only a example.',
    timestamp: new Date().toISOString(),
  }

  const encoder = new TextEncoder()
  const encodedPayload = encoder.encode(JSON.stringify(payload))

  const jwe = await new CompactEncrypt(encodedPayload)
    .setProtectedHeader({ alg: 'ECDH-ES', enc: 'A256GCM' })
    .encrypt(publicKey)

  console.log(jwe)


  const { plaintext, protectedHeader } = await compactDecrypt(jwe, privateKey)
  const decoded = new TextDecoder().decode(plaintext)

  console.log(protectedHeader)
  console.log(JSON.parse(decoded))

needs have installed Node.js and module jose, to install module needs use this comand:
npm install [email protected]
