decipher.final([outputEncoding])

• outputEncoding <string> 返回值的 字符编码。

  ¥outputEncoding <string> The encoding of the return value.

• 返回：<Buffer> | <string> 任何剩余的解密内容。如果指定了 outputEncoding，则返回字符串。如果未提供 outputEncoding，则返回 Buffer。

  ¥Returns: <Buffer> | <string> Any remaining deciphered contents. If outputEncoding is specified, a string is returned. If an outputEncoding is not provided, a Buffer is returned.

一旦调用了 decipher.final() 方法，就不能再使用 Decipheriv 对象来解密数据。多次尝试调用 decipher.final() 将导致抛出错误。

¥Once the decipher.final() method has been called, the Decipheriv object can no longer be used to decrypt data. Attempts to call decipher.final() more than once will result in an error being thrown.
