Can't base64 (or even Math::Base85 ) do chunks?

Untested, and I don't remember what the 57 * 60 is all about. :-) Probably something to do with ideal chunk size for base64. 

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

#encode
open INFILE, '<', $ARGV[0];
binmode INFILE;
open OUTFILE, '>', $ARGV[1];
my $buf;
while ( read( INFILE, $buf, 60 * 57 ) ) {
    print OUTFILE encode_base64($buf);
}

close OUTFILE;
close INFILE;

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

open INFILE,  '<', $ARGV[0];
open OUTFILE, '>', $ARGV[1];
binmode OUTFILE;
my $buf;
while ( $buf = <INFILE> ) {
    print OUTFILE decode_base64($buf);
}

close OUTFILE;
close INFILE;
