This is a utility function that successively calls <CODE><A href="NETSHA1Init.html">NETSHA1Init</A></CODE>, <CODE><A href="NETSHA1Update.html">NETSHA1Update</A></CODE>, and <CODE><A href="NETSHA1GetDigest.html">NETSHA1GetDigest</A></CODE>.</p> 42<p>Any size and alignment position can be used for the input data.</p> 43<p> 44Be sure to pass enough memory region in the digest argument to store the hash length to be generated.<br>Since the context structure is allocated internally, make sure that you have sufficient stack when calling the function. For details, see the "SHA-1" section of the <a href="hash_overview.html">hash algorithm</a>. 45</p> 46<h2>See Also</h2> 47<P><A href="NETCalcSHA1.html"><CODE>NETCalcSHA1</CODE></A></P> 48<H2>Revision History</H2> 49<P> 502007/02/15 Corrected incorrect links.<BR> 2006/09/01 Initial version.<BR> 51</P> 52<hr><p>CONFIDENTIAL</p></body> 53</html> 54
