Base64 aes编码/解码

Question

我们的图书馆使用import com.sun.org.apache.xml.internal.security.utils.Base64;

似乎鼓励我们使用别的东西  import org.apache.commons.codec.binary.Base64; （Package com.sun.org.apache.xml.internal.security.utils.Base64 does not exist）

你必须更改加密/解密代码，我不知道应该如何更改它们。
截至目前，我收到Input length must be multiple of 16 when decrypting with padded cipher错误

（Encrypt and decrypt with AES and Base64 encoding）

任何人都想表明正确的方法吗？或者我强烈怀疑应该有一个git repo这样做但却找不到它..

import sun.misc.BASE64Decoder;
 import sun.misc.BASE64Encoder;
