You can use this base64 sample decoder and encoder to:
- Decode base64 strings (base64 string looks like YTM0NZomIzI2OTsmIzM0NTueYQ==)
- Decode a base64 encoded file (for example ICO files or files from MIME message)
- Convert text data from several code pages and encode them to a base64 string or a file
- New: Try CSS images to base64 - CSS data URI analyzer

This online sample demonstrates functionality of
and Huge asp file upload
You can convert texts using several code pages (using CharSet
property) from Unicode string to byte array and then convert the binary data to a Base64 string.
The sample uses a special Base64 algorithm written for the ByteArray
class. The Base64 conversion algorithm is written in C++ and works with binary (VT_ARRAY | VT_UI1) and String (BSTR) OLE data. It contains hi-speed and low-memory consumption BSTR->BSTR, BSTR->BINARY, BINARY->BSTR and BSTR->BSTR algorithms. Source code of the coding algorithm is available within distribution license
of a ScriptUtilities
class was primarily designed
to work with ASP and VBScript, but you can use it with any other language working with COM (ActiveX, OLE) objects,
such is VBA (VBA5, VBA6, Word, Excel, MS Access), VBScript and JScript in windows scripting host
(.wsh, .chm or .hta applications, Outlook or echange server-side scripts), VB.Net, C# or j# in ASP.Net and others.
