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.
