I have added ConfigurationOfNacl to Pharo 3 repository. You can load it using the Configuration Browser.
Nacl is a cryptolibrary based in libsodium. The binding for Pharo/Squeak ( http://www.eighty-twenty.org/index.cgi/tech/smalltalk/nacl-for-squeak-and-pharo-20130601.html) was written by Tony-Garnock Jones. The Configuration automatically download and uncompress the compiled library file. I have tested under Windows and Linux, all tests passes. But I do not own a Mac (I'm really open to donations :) so if anyone may test the configuration under Mac it would be nice. Cheers, Hernán
