I have a series of binary strings, such as: 
$str = "00000001001000110100010101100111100010011010101111001101111011
+11"

I want to create a base64 representation of this for compression and storage in text format.

I've tried using Mime::Base64 with 

encode_base64(pack("B64", $str))

[download]
However, with that the result is 13 characters long starting from my 64 bit example. I'd rather get compression down to 4 characters in this case. How can I go about that? Also, is there a good solution for a base32 representation?

Update: As Grandfather politely points out, I am an idiot. :-). The minimum would be 11, not 4.
