* from a binary file
*
* Usage:
- * ./encrypt2 <xml-doc> <des-key-file>
+ * ./encrypt2 <xml-doc> <des-key-file>
*
* Example:
- * ./encrypt2 encrypt2-doc.xml deskey.bin > encrypt2-res.xml
+ * ./encrypt2 encrypt2-doc.xml deskey.bin > encrypt2-res.xml
*
* The result could be decrypted with decrypt1 example:
- * ./decrypt1 encrypt2-res.xml deskey.bin
+ * ./decrypt1 encrypt2-res.xml deskey.bin
*
* This is free software; see Copyright file in the source
