Hi, The requirements are quite clear and straightforward to implement. What you're asking is not possible with php, not without relying on extensions, namely openssl and gmp. I'm not well versed in perl but I think same limitations apply. We could have used python but any pure python crypto implementation is susceptible to side channel attacks, e.g python-ecdsa. Assuming you'll be on shared hosting I think that's a serious concern. As a result you'll need external tools like openssl with python too. In light of the above, I think one of the best options is golang. It's clear, concise and performant. Once built it has no dependency so you can run it just fine in cgi-bin context.
