Java和vb.net中的SHA-256不同值

Question

重新开始并不是一个选项，因为已经运行的项目使用SHA-256

这里是java代码---＆gt;＆gt;＆gt;只是一个简单的代码来散列任何字符串

    public static String SHA256 (String text) throws NoSuchAlgorithmException,    UnsupportedEncodingException
    {
textByte = text.getBytes("UTF-8");  
MessageDigest md = MessageDigest.getInstance("SHA-256");
textByte = md.digest(textByte);
return Base64.encodeToString(textByte,Base64.NO_CLOSE);
}

和VB代码如下

 Public Function EncryptPassword(ByVal password As String) As String
        Dim hashedPassword As String = Nothing
        Dim hashProvider As SHA256Managed = Nothing
        Try
            Dim passwordBytes() As Byte
            passwordBytes = System.Text.Encoding.Unicode.GetBytes(password)
            hashProvider = New SHA256Managed
            hashProvider.Initialize()
            passwordBytes = hashProvider.ComputeHash(passwordBytes)
            hashedPassword = Convert.ToBase64String(passwordBytes)
        Catch ex As Exception
        Finally
            If Not hashProvider Is Nothing Then
                hashProvider.Clear()
                hashProvider = Nothing
            End If
        End Try
        Return hashedPassword
    End Function

嗯，它可能不是唯一的问题，但VB中的System.Text.Encoding.Unicode是UTF-16LE，而您的Java代码使用的是UTF-8。
