下面的vb代码在java中的确切代码是什么，因为我没有得到相同的加密值

'使用三重DES加密字符串 私有函数TripleDESEncryptByVal str作为字符串作为TripleDESEncryptResult

    ' 3DES Encryption
    ' Generate KEY/IV pair for your local 3DES encrpytion on xmlCard

    ' Create a new 3DES CryptoProvider and generate KEY/IV pair for encryption
    Dim m_cryptoProvider As New TripleDESCryptoServiceProvider
    m_cryptoProvider.GenerateIV() 
    m_cryptoProvider.GenerateKey() 

    Dim stream As System.IO.MemoryStream = New System.IO.MemoryStream
    Dim cryptoStream As CryptoStream = _
      New CryptoStream(stream, m_cryptoProvider.CreateEncryptor, _
                          CryptoStreamMode.Write)

    Dim Input() As Byte = System.Text.Encoding.Default.GetBytes(str)

    cryptoStream.Write(Input, 0, Input.Length)
    cryptoStream.FlushFinalBlock()

下面的代码是用于3DES加密和解密的java代码。请尝试使用此代码。我希望它能帮助你

无法识别GenerateKey和GenerateIV方法背后的逻辑您的问题是什么？如何将上述vb.net代码转换为java/到目前为止您是否尝试过任何操作？是的，我尝试了大量代码，但没有得到与vb.net相同的确切加密值。我尝试了您的代码Anil Reddy，但仍然没有得到相同的加密值。但是谢谢你的帮助..你有任何异常吗？没有成功执行它，但加密值与vb.net代码不同。我只需要编写代码，其中加密值应与vb.net代码加密值相同。加密值取决于你在vb.net代码中使用的密钥。在此代码中使用相同的密钥和相同的数据。您将获得相同的加密值
