* DES key (encrypted with an RSA key).
*
* Usage:
- * ./encrypt3 <xml-doc> <rsa-pem-key-file>
+ * ./encrypt3 <xml-doc> <rsa-pem-key-file>
*
* Example:
- * ./encrypt3 encrypt3-doc.xml rsakey.pem > encrypt3-res.xml
+ * ./encrypt3 encrypt3-doc.xml rsakey.pem > encrypt3-res.xml
*
* The result could be decrypted with decrypt3 example:
- * ./decrypt3 encrypt3-res.xml
+ * ./decrypt3 encrypt3-res.xml
*
* This is free software; see Copyright file in the source
* distribution for preciese wording.
