in reply to Best technique to code/decode binary data for inter-machine communication?

Is there something better than MIME::Base64?

Since we are just talking about making printable characters for transmission, you would want to shorten the length of the string, so how about using Math::BaseCnv to go from Base64 to Base128? Or use compression on the file, before doing the base conversion, with something like

#!/usr/bin/perl use Compress::Zlib; use MIME::Base64; my $str = "Hello World! " x 3; my $gzip = Compress::Zlib::memGzip( $str ); my $hex = unpack 'H*', $gzip; my $base64 = encode_base64('Aladdin:open sesame'); my $str_len = length($str); my $gzip_len = length($gzip); my $hex_len = length($hex); my $base64_len = length($base64); # make binary printable ;-) $gzip = '#' x $gzip_len; printf "%3d: %s\n%3d: %s\n%3d: %s\n%3d: %s\n", $str_len, $str, $gzip_len, $gzip, $hex_len, $hex, $base64_len, $bas +e64; __DATA__ 39: Hello World! Hello World! Hello World! 36: #################################### 72: 1f8b0800000000000003f348cdc9c95708cf2fca495154f0c0c90100b9a8ae3827 +000000 29: QWxhZGRpbjpvcGVuIHNlc2FtZQ==
