Hi,

I have a Visual Basic application which uses Xceed Binary Endocing library v1.1, Encryption library v1,1 and Streaming compression library v1.1.

Using the Xceed components, the data is compressed, encrypted, encoded to base 64 then sent by an email. I am writing a new web service

to read the data, decode from Base64, decrypt then uncompress. Streaming compression and binary encoding seems to be discountinued

on .NET. Is there a way to decode from Base64, decrypt then uncompress the data without using ActiveX Xceed components (using Interops)?

Following is the current process which uses ActiveX components.

Source Data: Binary

1. Compress the binary data using XceedStreamingCompression. Compression format is standard.

2. Encrypt the compressed data using XceedEncryption. Method is Rijndael with SHA hashing method.

3. Encode using XceedBinaryEncoding to base 64.

Thanks in advance.
