ConvertPublicKey + SharedKey #14

Closed redDwarf03 closed 3 years ago

redDwarf03 commented 3 years ago

Hello thanks for your work

I would like to use your library to translate this js code:

const { public: ephemeralPublicKey, private: ephemeralPrivateKey} = curve25519.generateKeyPair(randomBytes(32))  
const curve25519pub = ed2curve.convertPublicKey(pubBuf)

var sharedKey = curve25519.sharedKey(ephemeralPrivateKey, curve25519pub)

But I don't know how. Is it possible with your library ?

Best

Hi,

There is a conversion utility to use ed25519 for encryption/decryption, that you can use to achieve what you want.
