OpenSSL加密密钥和IV与Java程序生成的密钥不同

我正在修改Java程序以解密由OpenSSL加密的密码。现在我得到以下异常

Exception in thread "main" javax.crypto.BadPaddingException: Given final block not properly padded. Such issues can arise if a bad key is used during decryption.
    at com.sun.crypto.provider.CipherCore.doFinal(CipherCore.java:991)
    at com.sun.crypto.provider.CipherCore.doFinal(CipherCore.java:847)
    at com.sun.crypto.provider.AESCipher.engineDoFinal(AESCipher.java:446)
    at javax.crypto.Cipher.doFinal(Cipher.java:2222)
    at test.TestAesDecrypt.main(TestAesDecrypt.java:107)

通过各种链接，可以理解这是由于生成的密钥不同所致。OpenSSL和程序中使用的密钥和iv不同。这些由OpenSSL和程序在内部生成。

如果我将OpenSSL密钥硬编码并进行编程，则解密有效。

加密的密码是helloworld！

密码是TIKpasskey001002。原始程序是从这里开始的。

我该如何解决？
