pushssl – attach SSL version 2 encryption to a communication channel |
SYNOPSIS
|
#include <u.h> #include <libc.h>
int pushssl(int fd, char *alg, char *secin, char *secout, int
*cfd) |
DESCRIPTION
|
Pushssl opens an ssl(3) device, connects it to the communications
channel fd, and starts up encryption and message authentication
as specified in alg. The algorithms are separated by a space and
either can be first. See ssl(3) for the possible algorithms. Secin
and secout contain the encryption keys for the two
directions. If either is nil, the other is used in both directions.
If cfd is non–nil, the SSL control channel is opened and its fd
returned.
Pushssl returns a file descriptor for the SSL data channel. Anything
written to this descriptor will get encrypted and authenticated
and then written to the file descriptor, fd. |
