I have an encrypted file containing password information (via Xor encryption... and yes I know perils of using this sort of encryption).
I would like to be able to unencrypt the contents into a memory structure to manipulate the contents, rather than writing to a file.
The input file has 3 fields and is tab delimited.
serv login pass serv login pass serv login pass
Here's a snippet of the code I currently use to put the unencrypted contents into an array.
open(IN, $ARGV[2]) or die "Can't read $ARGV[2]: $!\n"; my ($in,@workarray); while( sysread(IN,$in,length($enckey)) ) { push @workarray,$in^substr($enckey,0,length($in)); }
The problem is that each element of the array does not finish on a delimiter boundary.
e.g.
print "Value is : $workarray[0]"; print "Value is : $workarray[1]"; print "Value is : $workarray[2]"; print "Value is : $workarray[3]"; print "Value is : $workarray[4]"; print "Value is : $workarray[5]";
gives me
Value is : SYB_SERV_DEV Value is : joe_blogg Value is : s nopasswor Value is : d SYB_SERV Value is : C_OTC joe_ Value is : bloggs nopa
When I was expecting
Value is : SYB_SERV_DEV Value is : joe_bloggs Value is : nopassword Value is : SYB_SERVC_OTC Value is : joe_bloggs Value is : nopassword
hence searching elements of the array is proving fruitless.
I'm sure there are better ways of doing this (I'm relatively new to perl). Any comments on how to clean this up would be useful.
