Function encode_secured_submessage 

pub fn encode_secured_submessage(
    plugin: &dyn CryptographicPlugin,
    local: CryptoHandle,
    remote_list: &[CryptoHandle],
    plaintext: &[u8],
) -> Result<Vec<u8>, SecurityRtpsError>

Encodes a plain submessage blob as a secured submessage sequence (SEC_PREFIX + SEC_BODY + SEC_POSTFIX).

The crypto plugin produces the actual ciphertext; this module only takes care of the wire framing.

Errors

A passed-through crypto error or a length overflow (u16).
