Greetings Experts! <br />
<br />
Will you send me an example of how to create the RijndaelManaged key and the vector and then how to convert it to a format I can save on the web.config, you see, I created it using RijndaelManaged.GenerateKe<wbr />y() and RijndaelManaged.GenerateIV<wbr />() then converted to a string and saved it on the web.config . However when I retrieve the value from the web.config and then use Encoding.ASCII.GetBytes(&quot;K<wbr />ey&quot;) to pass the value to RijndaelManged.Key I get error: &quot;Specified key is not a valid size for this algorithm&quot;. I hope this is clear, I really appreciate your help with this, I am stuck. I am using VS 2010, ASP.NET 4.0 with VB.NET 4.0,

The .NET Framework is not specific to any one programming language; rather, it includes a library of functions that allows developers to rapidly build applications. Several supported languages include C#, VB.NET, C++ or ASP.NET.

.NET Programming

Network security consists of the policies adopted to prevent and monitor authorized access, misuse, modification, or denial of a computer network and network-accessible resources. Network security involves the authorization of access to data in a network, and covers a variety of computer networks; conducting transactions and communications among businesses, government agencies and individuals. Networks can be private, such as within a company, and others which might be open to public access.

Network Security

Encryption is the process of encoding messages or information in such a way that only authorized parties can read it. In an encryption scheme, the intended communication information or message, referred to as plaintext, is encrypted using an encryption algorithm, generating ciphertext that can only be read if decrypted. For technical reasons, an encryption scheme usually uses a pseudo-random encryption key generated by an algorithm. An authorized recipient can easily decrypt the message with the key provided by the originator to recipients, but not to unauthorized interceptors.
