Encrypt a plaintext for the recipient set using olm_pk_encryption_set_recipient_key. Writes to the ciphertext, mac, and ephemeral_key buffers, whose values should be sent to the recipient. mac is a Message Authentication Code to ensure that the data is received and decrypted properly. ephemeral_key is the public part of the ephemeral key used (together with the recipient's key) to generate a symmetric encryption key. Returns olm_error() on failure. If the ciphertext, mac, or ephemeral_key buffers were too small then olm_pk_encryption_last_error() will be "OUTPUT_BUFFER_TOO_SMALL". If there weren't enough random bytes then olm_pk_encryption_last_error() will be "OLM_INPUT_BUFFER_TOO_SMALL".
