DESCRIPTION

   pg_hmac.pl implements functionality to seal a file to
   be sent to Nordea PlusGirot
   See the following urls
   http://www.plusgirot.se/Programleverantörer/Kommunikation+och+säkerhet/HMAC/1088002.html
   
   
   This is similar to the BGC HMAC
   For more information about BGC HMAC, 
   visit the website www.bgc.se/hmac 
   
   The source code is in charset encoding ISO-8859-1
   
   The files that should be sealed should be in 
   charset encoding ISO-8859-1
   
   The line separator should be CRLF for the files to be sealed
   The command "cpanp" (CPANPLUS) may be used in cygwin 
   to install the Digest::SHA perl module
   Tripple check your keyfile, it should not contain CRLF 
   and have the correct length
   Note that this program doesn't add the 
   %001 Transmissopn header
   %002 Transmission trailer

EXIT CODES

   0 success
   anything else indicates failure

EXAMPLES

 if executed from within Eclipse
 using EPIC
 using cygwin perl
 the arguments may look like this
 --infile /cygdrive/c/Users/frost/workspace/bgc_hmac/src/pgin.txt 
 --keyfile /cygdrive/c/Users/frost/workspace/bgc_hmac/src/key.txt 
 --outfile /cygdrive/c/Users/frost/workspace/bgc_hmac/src/pgout.txt
