G'day, monks. I've been playing with SQLite alot lately, and I'm trying to find a way to add binary attachments to the database. The SQLite docs recommend Base64 encoding, so I thought I'd experiment with that a bit.

Here's my program to encode files in Base64:

#! /usr/bin/perl
use strict;
use MIME::Base64 qw( encode_base64 );
use IO::All;

encode_base64( io( $ARGV[0] )->slurp ) > io( $ARGV[1] );

__END__

[download]

And the matching decode program:

#! /usr/bin/perl
use strict;
use MIME::Base64 qw( decode_base64 );
use IO::All;

decode_base64( io( $ARGV[0] )->slurp ) > io( $ARGV[1] );

__END__

[download]

Here's what I tried to test it:

Z:\>perl encode_base64.pl yearsinservice.pdf yis.b64

Z:\>perl decode_base64.pl yis.b64 yis.pdf

[download]

When I try to open yis.pdf with Acrobat Reader, it says there's an error in the file. The original PDF works fine. Any suggestions?

UPDATE: I moved these PDFs to my Linux box and used hexdump -C to look at them - it looks like an endline issue (yis.pdf has Windows-style endlines). I tried adding local $/ = "\n"; to each file, but that didn't seem to help.
