curve 25519 scalar multiplication library

Question

I am porting some backend/sdk to nodejs/typescript and I came along a blocker, the source uses libsodium function crypto_scalarmult_curve25519() which has an equivalent in Go as well thru crypto/curve25519 ( ScalarMult ).

It's been hour since I was looking a similar version in nodejs/typescript, I even tried the javascript version of libsodium ; which pointed me to libsodium-wrapper , which unfortunately the function I am looking for ( crypto_scalarmult_curve25519 ) is missing and not supported. crypto library nor the node-forge does not have curve scalar multiplication as well.

Is there any alternative in javascript/typescript?

Answer 1

found a very lightweight curve25519 library for typescript. https://github.com/harveyconnor/curve25519-js/

by default the scalar multiplication functions is not exposed to outside user of the library, so i need to export it from the source to be used.

answering my question for others to use.
