As OpenSSL does not support asynchronous read/write duplex, sometimes, the asynchronous read/write logic needs to be changed to consecutive processing. An interface for viewing the job status in internal objects maybe helpful for this.

ASYNC_JOB *SSL_get_job(const SSL *s)
{
    return s->job;
}

There's little information about what keys and values are in the output, what it means and how they are related to the screen output. In general that needs to be added. (special topics see #1675, #1674)

如：xxx app + www.xxx.com
