* Encrypts binary data using a template file and a DES key from a binary file
*
* Usage:
- * ./encrypt1 <xml-tmpl> <des-key-file>
+ * ./encrypt1 <xml-tmpl> <des-key-file>
*
* Example:
- * ./encrypt1 encrypt1-tmpl.xml deskey.bin > encrypt1-res.xml
+ * ./encrypt1 encrypt1-tmpl.xml deskey.bin > encrypt1-res.xml
*
* The result could be decrypted with decrypt1 example:
- * ./decrypt1 encrypt1-res.xml deskey.bin
+ * ./decrypt1 encrypt1-res.xml deskey.bin
*
* This is free software; see Copyright file in the source
* distribution for preciese wording.
