skcp

SKCP

SKCP is a library of encapsulation of KCP, it has the function of connection management and encryption.

state

"It's not that it can't be used", applied in SKCPTUN

characteristic

• The encrypted transmitted data has no characteristics
• Have basic connection management capabilities

environment

Operating environment: Linux, MacOS

Dependent libraries: OpenSSL, libev

use

The client code needs to implement the following in skcp_conf_t:

 void (*on_recv_cid)(skcp_t *skcp, uint32_t cid);
void (*on_recv_data)(skcp_t *skcp, uint32_t cid, char *buf, int len);
void (*on_close)(skcp_t *skcp, uint32_t cid);

The server code needs to implement the following in skcp_conf_t:

 void (*on_accept)(skcp_t *skcp, uint32_t cid);
int (*on_check_ticket)(skcp_t *skcp, char *ticket, int len);
void (*on_recv_data)(skcp_t *skcp, uint32_t cid, char *buf, int len);
void (*on_close)(skcp_t *skcp, uint32_t cid);

Compile the test code:

 cd skcp
mkdir build
make

test

Run the test server:

 cd build
./skcp_server

Currently, the test server command can only serve one client, which is a point-to-point service. If more than one are needed, multiple skcp_server processes need to be started, like "netcat". Get help via the "-h" parameter. By default, it listens to port 6060 at the 127.0.0.1 address. You can specify the listening network interface and port as well as the encryption key through parameters:

 ./skcp_server -a 0.0.0.0 -p 8080 -k yourpassword

Run the test client:

 cd build
./skcp_client

Get help via the "-h" parameter. By default, port 6060 of the 127.0.0.1 address is connected. You can specify the network interface and port to be connected and the encryption key through parameters:

 ./skcp_client -a 127.0.0.1 -p 8080 -k yourpassword
