34<P>This function initializes the <CODE><A href="NETSHA1Context.html">NETSHA1Context</A></CODE> type context structure used in calculating SHA-1. Make sure that this function is called before using the <CODE><A href="NETSHA1Update.html">NETSHA1Update</A></CODE> and <CODE><A href="NETSHA1GetDigest.html">NETSHA1GetDigest</A></CODE> functions.<BR>You can re-apply this function to a context structure that is already initialized. In this case, it will return the context structure to its initial state.</p>
