.TH PUSHSSL 2.SH NAMEpushssl \- attach SSL version 2 encryption to a communication channel.SH SYNOPSIS.B #include <u.h>.br.B #include <libc.h>.PP.Bint pushssl(int fd, char *alg, char *secin, char *secout, int *cfd).SH DESCRIPTION.I Pushsslopens an.IR ssl (3)device, connects it to the communications channel.IR fd ,and starts up encryption and message authentication as specifiedin.IR alg .The algorithms are separated by a space and either can be first.See.IR ssl (3)for the possible algorithms..I Secinand.I secoutcontain the encryption keys for the two directions.If either is nil, the other is used in both directions.If.I cfdis non-nil, the SSL control channel is opened and its fdreturned..PP.I Pushsslreturns a file descriptor for the SSL data channel.  Anything written to thisdescriptor will get encrypted and authenticated and then written to thefile descriptor,.IR fd ..SH SOURCE.B /sys/src/libc/9sys.SH "SEE ALSO".IR dial (2),.IR ssl (3),.SH DIAGNOSTICSreturn \-1 on failure.
