insanum / ecies Goto Github PK

Which version of openssl did you use? Does this solution works in latest version? I am failing to compile with 1.1.1g version.

ECIES requires a KDF to ensure random distribution of the entropy in the shared secret, or you void the AES security contract. See https://crypto.stackexchange.com/a/60898/349.

while ephemeral crypto is nice for PFS in communication, sometimes you want to encrypt for storage, and you dont want a pure symmetric encryption, as obviously whatever doing the backup would need the symmetric key.

and you dont really have a seperate transmitter and reciever, so the question is basically whether one cannot just use the public key to encrypt a random secret for symmetric encryption similar to RSA?
