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.
