base64 coding for zsh ?

[Marc Chantreux <marc.chantreux@xxxxxxxxxxxxxxxxxx>]

Hi all, 

I wrote a function that read ldif entry from a stream and store
attributes in an associative array.

so i can write :

ldapsearch uid=mc | while { ldif_entry_read } {
     for oc (  ${(P)u[objectClass]} ) { print $u[uid] is a $oc }
}

ldif_entry_free u

Now i want my function to deal with base64. The fact is, i don't know
how to do it.

Someone can help ? 

regards,
mc
