Use the flag (COP_FLAG_UPDATE)structure member to mark whether it is just input data.
like this:
can do manys times,just input data
....
```
cryp.ses = session.ses;
cryp.op = COP_ENCRYPT;
cryp.src = (caddr_t) s;
cryp.len = len;
cryp.flags = COP_FLAG_UPDATE;
cryp.dst = 0;
cryp.mac = (caddr_t) out;
cryp.iv = 0;
if (ioctl(cryptodev_fd, CIOCCRYPT, &cryp) == -1)
{
warn("CIOCCRYPT");
goto err;
}
can do manys times like frist...
then,the last time
Don't use any flay structure member to mark
this is last time,need get final result
....
cryp.ses = session.ses;
cryp.op = COP_ENCRYPT;
cryp.src = (caddr_t) s;
cryp.len = len;
cryp.flags = 0;
cryp.dst = 0;
cryp.mac = (caddr_t) out;
cryp.iv = 0;
if (ioctl(cryptodev_fd, CIOCCRYPT, &cryp) == -1)
{
warn("CIOCCRYPT");
goto err;
}
....
that will get last result.
