NAME
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 chan‐
nel fd, and starts up encryption and message authentication as speci‐
fied in alg. The algorithms are separated by a space and either can be
first. See ssl(3) for the possible algorithms. Secin and secout con‐
tain 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. Pushssl closes the original
file descriptor fd on success.
