Calculate shared-secret using X25519 and RSA keys #179

Closed xErik closed 6 months ago

xErik commented 6 months ago

I have three RSA PEMs:

I'd like to use these to calculate a Shared Key.

Is it possible to create a SimplePublicKey from RSA PEMs with this libary?

final List<int> publicKeyDataSelf = ...

SimplePublicKey publickKeySelf =
  SimplePublicKey(publicKeyDataSelf, type: KeyPairType.rsa);
