in reply to How to generate 64-character length lines in base64?

MIME::Base64 is a very small module, and the encode method is particularly small, since pack() does most of the work. They use pack to create a uuencoded string, then tr// to translate from the uuencode charset to the Base64 charset: Copying the source, then, with a few minor modifications

sub b6464 { my $orig=shift; my $string = pack("u",$orig); $string =~ s/^.//mg; $string =~ s/\n//g; # use tr to translate from UUE to Base64 $string =~ tr|` -_|AA-Za-z0-9+/|; # fix padding at the end my $padding = (3 - length($orig) % 3) % 3; $string =~ s/.{$padding}$/'=' x $padding/e if $padding; # break string into lines of 64 chars or less $string =~ s/(.{1,64})/$1\n/g; return $string; }
