The base64 encoding is designed to represent -arbitrary sequences of octets in a form that need not be humanly -readable. A 65-character subset ([A-Za-z0-9+/=]) of US-ASCII is used, -enabling 6 bits to be represented per printable character. - -The following functions are provided: - -=over 4 - -=item encode_base64($str) - -=item encode_base64($str, $eol); - -Encode data by calling the encode_base64() function. The first -argument is the string to encode. The second argument is the -line-ending sequence to use. It is optional and defaults to "\n". The -returned encoded string is broken into lines of no more than 76 -characters each and it will end with $eol unless it is empty. Pass an -empty string as second argument if you do not want the encoded string -to be broken into lines. - -=item decode_base64($str) - -Decode a base64 string by calling the decode_base64() function. This -function takes a single argument which is the string to decode and -returns the decoded data. - -Any character not part of the 65-character base64 subset is -silently ignored. Characters occurring after a '=' padding character -are never decoded. - -If the length of the string to decode, after ignoring -non-base64 chars, is not a multiple of 4 or if padding occurs too early, -then a warning is generated if perl is running under C<-w>. - -=back - -If you prefer not to import these routines into your namespace, you can -call them as: - - use MIME::Base64 (); - $encoded = MIME::Base64::encode($decoded); - $decoded = MIME::Base64::decode($encoded); - -=head1 DIAGNOSTICS - -The following warnings can be generated if perl is invoked with the -C<-w> switch: - -=over 4 - -=item Premature end of base64 data - -The number of characters to decode is not a multiple of 4. Legal -base64 data should be padded with one or two "=" characters to make -its length a multiple of 4. The decoded result will be the same -whether the padding is present or not. - -=item Premature padding of base64 data - -The '=' padding character occurs as the first or second character -in a base64 quartet. - -=back - -The following exception can be raised: - -=over 4 - -=item Wide character in subroutine entry - -The string passed to encode_base64() contains characters with code -above 255. The base64 encoding is only defined for single-byte -characters. Use the Encode module to select the byte encoding you -want. - -=back - -=head1 EXAMPLES - -If you want to encode a large file, you should encode it in chunks -that are a multiple of 57 bytes. This ensures that the base64 lines -line up and that you do not end up with padding in the middle. 57 -bytes of data fills one complete base64 line (76 == 57*4/3): - - use MIME::Base64 qw(encode_base64); - - open(FILE, "/var/log/wtmp") or die "$!"; - while (read(FILE, $buf, 60*57)) { - print encode_base64($buf); - } - -or if you know you have enough memory - - use MIME::Base64 qw(encode_base64); - local($/) = undef; # slurp - print encode_base64(<STDIN>); - -The same approach as a command line: - - perl -MMIME::Base64 -0777 -ne 'print encode_base64($_)' <file - -Decoding does not need slurp mode if every line contains a multiple -of four base64 chars: - - perl -MMIME::Base64 -ne 'print decode_base64($_)' <file - -Perl v5.8 and better allow extended Unicode characters in strings. -Such strings cannot be encoded directly, as the base64 -encoding is only defined for single-byte characters. The solution is -to use the Encode module to select the byte encoding you want. For -example: - - use MIME::Base64 qw(encode_base64); - use Encode qw(encode); - - $encoded = encode_base64(encode("UTF-8", "\x{FFFF}\n")); - print $encoded; - -=head1 COPYRIGHT - -Copyright 1995-1999, 2001-2004 Gisle Aas. - -This library is free software; you can redistribute it and/or -modify it under the same terms as Perl itself. - -Distantly based on LWP::Base64 written by Martijn Koster -<m.koster@nexor.co.uk> and Joerg Reichelt <j.reichelt@nexor.co.uk> and -code posted to comp.lang.perl <3pd2lp$6gf@wsinti07.win.tue.nl> by Hans -Mulder <hansm@wsinti07.win.tue.nl> - -The XS implementation uses code from metamail.
