Don't use reserved name "_encrypt" for parameters;
instead I've picked "enc", because that's what's in the prototypes. ("_encrypt" is reserved only as an external name, but still using it in an application doesn't look like good style to me -- and it certainly isn't if the point is just avoiding shadowing, which is apparently why the previous name "encrypt" was changed.)
