具有AES192的无效IV长度

Question

由于createCipher已弃用，我正在更新旧功能以加密密码。这是我的旧功能：

  encrypt(payload) {
    let AES192 = crypto.createCipher('aes192', Buffer.from(config.secret))
    let crypted = AES192.update(payload, 'utf8', 'hex')
    crypted += AES192.final('hex')
    return crypted
  },
  decrypt(payload) {
    let AES192 = crypto.createDecipher('aes192', Buffer.from(config.secret))
    let decrypted = AES192.update(payload, 'hex', 'utf8')
    decrypted += AES192.final('utf8')
    return decrypted
  }

这是我试图做的：

  encrypt(payload) {
    const iv = crypto.randomBytes(96)
    const cipher = crypto.createCipheriv('aes192', Buffer.from(config.secret, 'hex'), iv)
    const encrypted = cipher.update(payload)
    encrypted = Buffer.concat([encrypted, cipher.final()])
    return iv.toString('hex') + ':' + encrypted.toString('hex')
  },
  decrypt(payload) {
    let textParts = payload.split(':')
    let iv = Buffer.from(textParts.shift(), 'hex')
    let encryptedText = Buffer.from(textParts.join(':'), 'hex')
    let decipher = crypto.createDecipheriv('aes192', Buffer.from(config.secret, 'hex'), iv)
    let decrypted = decipher.update(encryptedText)
    decrypted = Buffer.concat([decrypted, decipher.final()])
    return decrypted.toString()
  }

但是尝试执行此操作时出现此错误：

Error: Invalid IV length
    at Cipheriv.createCipherBase (internal/crypto/cipher.js:103:19)
    at Cipheriv.createCipherWithIV (internal/crypto/cipher.js:121:20)
    at new Cipheriv (internal/crypto/cipher.js:225:22)
    at Object.createCipheriv (crypto.js:119:10)

对于这一行，我尝试了多个值，例如12、16、32、124等。但是没有一个起作用const iv = crypto.randomBytes（96）
