javax.crypto.BadPaddingException: Given final block not properly padded. Such issues can arise if a bad key is used during decryption.

回答: 引发javax.crypto.BadPaddingException异常的原因是在解密过程中使用了错误的密钥。\[1\]根据引用\[2\]的分析，当进行3DES加密时，如果最后一位不足64位，会自动补上，导致解密时报错。而引用\[3\]提供了一个DES解密的代码，其中在执行cipher.doFinal()时报错BadPaddingException。为了解决这个问题，有两种方法可供选择。一种是不使用openjdk，另一种是检查密钥是否正确。
