    Encrypt a message by authenticated-encryption scheme.

    Sender can encrypt a confidential message specifically for Recipient, using Sender's public key.
    Using Recipient's public key, Sender can compute a shared secret key.
    Using Sender's public key and his secret key, Recipient can compute the exact same shared secret key.
    That shared secret key can be used to verify that the encrypted message was not tampered with,
    before eventually decrypting it.

    Note to use DID keys with this function you can call indy_key_for_did to get key id (verkey)
    for specific DID.
