There is a cpan provided Perl module MIME::Base64, using this, you can do the base64 decoding and encoding process easily.
Base64 is use exactly 64 character, and using the 64 characters one string converts into a totally different looks shape. The 64 characters are using at base64 are A-Z, a-z, 0-9, + and /
While any extra bit of padding requires, an equal(=) sign just used other than 64 characters. Below is a simple example that will just convert the timestamp integer into base64 string. And return it into integer form after decoding.
To learn more about base64 encoding and decoding, here is wikipedia http://en.wikipedia.org/wiki/Base64
Also can take a look it at from cpan http://search.cpan.org/~gaas/MIME-Base64-Perl-1.00/lib/MIME/Base64/Perl.pm

use MIME::Base64;
$base64_string = time();
$encoded = encode_base64($base64_string);
print "Encode $encoded";
## now decode this encoded data again.
$decoded = decode_base64($encoded);
print "Decode $decoded";To learn more about base64 encoding and decoding, here is wikipedia http://en.wikipedia.org/wiki/Base64
