*  The HTTP component now includes a method to generate
*  the current date/time in RFC 2616 compliant format.

*  It will become available in the next new version dated after
*  18-June-2008.

*  By setting the charset = "utf-8", the string will be converted
*  to utf-8 (internal to the Chilkat component) prior to signing:
loCrypt.Charset = "utf-8"

loCrypt.EncodingMode = "base64"
