I have a question, which Unicode encoding to use while encoding .NET string into base64? I know strings are UTF-16 encoded on Windows, so is my way of encoding is the right one? public static String ToBase64String(this String source) { return Convert.ToBase64String(Encoding.Unicode.GetBytes(source)); } ...
I am trying to decode a base64 encoded EMF image from an XML document in my application and render it on screen, however, it never seems to appear. If I copy/paste the data from the XML document into Notepad++ and use the Base64 Decode option and save the file as a .emf it opens fine in mspaint. So I think the issue is how I am decoding...
I'm trying to code a simple base64 encoder/decoder (to test my programming skill). I can compile it, but it doesn't link, I've this message error: C:\Documents and Settings\Facon\Escritorio>g++ base64.o main.o -o prueba.exe main.o:main.cpp:(.text+0x24a): undefined reference to `Base64Encode(std::vector > const&)' collect2:...

Just found the MIG Base 64 utility but its over 6 years old since its last release. It would appear to be quicker than the Apache commons equivalent but I have yet to confirm by writing up an actual test. Has anyone verified its correctness which is always a worry. If someone takes a look at the methods, please note i a referring to the ...
Well, not my server. My friend found it and sent it to me, trying to make sense of it. What it appears to be is a PHP IRC bot, but I have no idea how to decode it and make any sense of it. Here is the code: <?eval(gzinflate(base64_decode('some base 64 code here')))?> So I decoded the base64, and it output a ton of strange characters, ...
My knowledge about base64 is pretty limited. I am using it as an alternative to string escaping in a content management system, for I had been warned about how weaknesses have been found in mysql_real_escape_string(); and quite sheepishly so, as I am aware of how it buffs text size up. PHP seems to truncate everything after an instance ...
This is a string (see below, after the dashed line) in a database.inf file for a free program I downloaded that lists some websites. The file is plain text as you can see , but there is a string after it that looks base64 encoded (due to the end chars of ==). But b64_decoding it gives giberish. I wanted to decode it so I could add to t...
Is it possible to display a base64 encrypted image into a JTextPane ? Here my code JTextPane jTextPane = new JTextPane(); javax.swing.text.html.HTMLEditorKit eKit = new javax.swing.text.html.HTMLEditorKit(); jTextPane.setEditorKit(eKit); jTextPane.setContentType("text/html"); // my base64 image, used then in the img tag in the html...
I have an application, currently written in C#, which can take a Base64-encoded string and turn it into an Image (a TIFF image in this case), and vice versa. In C# this is actually pretty simple. private byte[] ImageToByteArray(Image img) { MemoryStream ms = new MemoryStream(); img.Save(ms, System.Drawing.Imaging...
Hello, I am trying to get the base64 content of a MimePart in a MimeMultiPart, but I'm struggling with the Javamail package. I simply want the base64 encoded String of a certain inline image, there doesn't seem to be an easy way to do this though. I wrote a method that will take the mime content (as a string) and an image name as a para...
I am receiving a BASE64 encoded string from a WebService. The string represents an HTML page, and I can use built-in ColdFusion functions to convert and display it. However, I need a GIF representation of the HTML page, and I'm wondering if there's any way to do this using ColdFusion. NOTE: The website I'm working on is ColdFusion 8. U...
I am passing a byte array from a java server to an iPad client in XML. The server is using xstream to convert the byte array to XML with the EncodedByteArrayConverter, which should convert the array to Base 64. Using xstream, I can decode the xml back to the proper byte array in a java client, but in the iPad client, I'm getting an inv...

In my ASP.NET MVC app I'm using jQuery Treeview with Async node expansion to build a tree of Active Directory objects. I'm encoding id's of each node with Base64 due to request length issue. For example in response for http://devel.local:49210/Domain/LeafExpand?root=source I get the following: [{"text":"DC=anusiewicz,DC=pl","id":"REM9YW...
I asked a question recently, How can I create an Image in GDI+ from a Base64-Encoded string in C++?, which got a response that led me to the answer. Now I need to do the opposite - I have an Image in GDI+ whose image data I need to turn into a Base64-Encoded string. Due to its nature, it's not straightforward. The crux of the issue is ...
