[Click] Encryption Functions

[Eddie Kohler]

Hi Jason,

Sorry for not responding earlier.  First off, we'd love to host a copy of your 
elements once they are ready; or add a link to them off our packages page on 
the wiki.  Second off, it just sounds like you've called cp_va_parse with 
incorrect arguments.  Unfortunately cp_va_parse, as a varargs function, 
baffles the compiler, which is unable to generate useful warnings.  If this is 
still a problem (& I bet it's not) feel free to send the cp_va_parse call to 
the list.

Eddie
