61 * DECnet object for servicing SSL. We accept the inbound and speak a
62 * simple protocol for multiplexing the 2 data streams (application and
63 * ssl data) over this logical link.
66 * SSL_CIPHER Defines a list of cipher specifications the server
67 * will support in order of preference.
68 * SSL_SERVER_CERTIFICATE
69 * Points to PEM (privacy enhanced mail) file that
70 * contains the server certificate and private password.
71 * SYS$NET Logical created by netserver.exe as hook for completing
72 * DECnet logical link.
74 * Each NSP message sent over the DECnet link has the following structure:
79 * char data[MAX_DATA];
82 * The channel field designates the virtual data stream this message applies
84 * A - Application data (payload).
85 * R - Remote client connection that initiated the SSL connection. Encrypted
86 * data is sent over this connection.
87 * G - General data, reserved for future use.
89 * The data streams are half-duplex read/write and have following functions:
90 * G - Get, requests that up to msg.length bytes of data be returned. The
91 * data is returned in the next 'C' function response that matches the
93 * P - Put, requests that the first msg.length bytes of msg.data be appended
94 * to the designated stream.
95 * C - Confirms a get or put. Every get and put will get a confirm response,
96 * you cannot initiate another function on a channel until the previous
97 * operation has been confirmed.
99 * The 2 channels may interleave their operations, for example:
100 * Server msg Client msg
103 * R, Confirm, {hello} ---->
104 * <---- R, put, {srv hello}
105 * R, Confirm, 0 ---->
106 * . (SSL handshake completed)
107 * . (read first app data).
108 * <---- A, confirm, {http data}
109 * A, Put, {http data} ---->
110 * <---- A, confirm, 0
112 * The length field is not permitted to be larger that 4092 bytes.
