I’d rather not.

Almost all *25519* code in existence is derived from DJB’s which
is labelled as being in the public domain, but lacks a fallback
licence for those jurisdictions where people cannot just waive
copyright (and DJB is notorious in not handing out those). I know
of one independent implementation under GPL, which would therefore
not be a choice.

<igli> just about the worst way you could do something like that, afaic.
<igli> it's like anti-design.  <mirabilos> that too… may I quote you on that?
<igli> sure, tho i doubt anyone will listen ;)
