I have searched for McEliece in PHP and found nothing. In JavaScript, there are several implementations but they are either with fixed parameters or just “proof-of-concept” without appropriate usability, crypto-resistance, performance etc. In Blueprints, there is also nothing.

I want to create a game server that one connect to from Unreal Engine and browser (game client and player cabinet). So I need secure, fast and suitable for novice implementation of McEliece with user-defined m and t, and n equal to 2^m in above-mentioned programming languages. But if I have badly searched and such implementation has already been existing, the link to it is also acceptable.
