Send Encoded Bytes over a Socket

See more Socket/SSL/TLS Examples

Demonstrates Socket.SendBytesENC, which decodes text using a named encoding (such as base64) and sends the resulting binary bytes.

Background. The ENC methods move raw binary data to and from printable text using a named encoding such as base64 or hex, which is convenient for logging or for handling binary data as strings.
