44<p>Returns TRUE if the AES encryption context has been generated correctly. Otherwise, returns FALSE.</p>
45<H2>Description</H2>
46<p>This function generates an AES encryption context. Make sure that this function is called before using <A href="NETAESEncrypt.html"><CODE>NETAESEncrypt</CODE></A> and <A href="NETAESDecrypt.html"><CODE>NETAESDecrypt</CODE></A>.<BR>You must also call <A href="NETAESDelete.html"><CODE>NETAESDelete</CODE></A> to release the context after using these functions.
47</p>
48<h2>Note</h2>
49<ul>
50<li>To bolster the robustness of the encryption, the initial vector should be a random byte string, and a different value should be used for each set of plain text being encrypted.</li>
51<li>The initial vector used at the time of decryption must be the same as the initial vector that is specified by this function at the time of encryption.</li>
52</ul>
