PUSHSSL(2)PUSHSSL(2)
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 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.
Pushssl
closes the original file descriptor
fd
on success.
