| /*- |
| * DECnet object for servicing SSL. We accept the inbound and speak a |
| * simple protocol for multiplexing the 2 data streams (application and |
| * ssl data) over this logical link. |
| * |
| * Logical names: |
| * SSL_CIPHER Defines a list of cipher specifications the server |
| * will support in order of preference. |
| * SSL_SERVER_CERTIFICATE |
| * Points to PEM (privacy enhanced mail) file that |
| * contains the server certificate and private password. |
| * SYS$NET Logical created by netserver.exe as hook for completing |
| * DECnet logical link. |
| * |
| * Each NSP message sent over the DECnet link has the following structure: |
| * struct rpc_msg { |
| * char channel; |
| * char function; |
| * short length; |
| * char data[MAX_DATA]; |
| * } msg; |
| * |
| * The channel field designates the virtual data stream this message applies |
| * to and is one of: |
| * A - Application data (payload). |
| * R - Remote client connection that initiated the SSL connection. Encrypted |
| * data is sent over this connection. |
| * G - General data, reserved for future use. |
| * |
| * The data streams are half-duplex read/write and have following functions: |
| * G - Get, requests that up to msg.length bytes of data be returned. The |
| * data is returned in the next 'C' function response that matches the |
| * requesting channel. |
| * P - Put, requests that the first msg.length bytes of msg.data be appended |
| * to the designated stream. |
| * C - Confirms a get or put. Every get and put will get a confirm response, |
| * you cannot initiate another function on a channel until the previous |
| * operation has been confirmed. |
| * |
| * The 2 channels may interleave their operations, for example: |
| * Server msg Client msg |
| * A, Get, 4092 ----> |
| * <---- R, get, 4092 |
| * R, Confirm, {hello} ----> |
| * <---- R, put, {srv hello} |
| * R, Confirm, 0 ----> |
| * . (SSL handshake completed) |
| * . (read first app data). |
| * <---- A, confirm, {http data} |
| * A, Put, {http data} ----> |
| * <---- A, confirm, 0 |
| * |
| * The length field is not permitted to be larger that 4092 bytes. |
