    ...ASCII or ISO text, certain parts of the input range -- many of the control characters <32; and characters >126 -- will not appear...
I hadn't thought about it but since the files were encrypted, more character sequences might appear.

As far as the 'SimCRC64' algorithm, it was just a simple CRC routine. I don't have the actual code, but it was something like this.

my $crc = crc64(\$output); ## Add crc check to output data sub crc64 ## Add crc check to output data { my $data = shift; my $crc = ""; my $len = length($$data); my $pos + = 0; while ( $pos < $len ) { $crc = $crc ^ ( substr($$data,$pos,8) ); $pos += 8; } return ( $crc ); }

It was part of the test to see what the worst case would be. As I previously said, I didn't expect the results.

Thank you
