Our app uses ECIES encryption to encrypt offers. Currently our biggest bottleneck when encrypting offers is generating ECDH shared secret.
Meaning that we need the following methods to be implemented:
❌ ecdh.computeSecret(otherPublicKey[, inputEncoding][, outputEncoding])
❌ ecdh.generateKeys([encoding[, format]])
❌ ecdh.getPrivateKey([encoding])
❌ ecdh.getPublicKey([encoding][, format])
❌ ecdh.setPrivateKey(privateKey[, encoding])
Curves that need to be supported: secp224r1 (P-224) and secp256k1 (P-256K).
We are using this library: https://github.com/margelo/react-native-quick-crypto/tree/main

secp224r1 (P-224)andsecp256k1 (P-256K).Also the implementation of ECDH is already done in Node: https://github.com/nodejs/node/blob/main/src/crypto/crypto_dh.cc
Also, there are tests inside the app and in TS: https://github.com/vexl-it/vexl-next/blob/main/packages/cryptography/src/operations/eciesLegacy.test.ts
