* Decrypts encrypted XML file using a single DES key from a binary file
*
* Usage:
- * ./decrypt1 <xml-enc> <des-key-file>
+ * ./decrypt1 <xml-enc> <des-key-file>
*
* Example:
- * ./decrypt1 encrypt1-res.xml deskey.bin
- * ./decrypt1 encrypt2-res.xml deskey.bin
+ * ./decrypt1 encrypt1-res.xml deskey.bin
+ * ./decrypt1 encrypt2-res.xml deskey.bin
