+.IP \(bu 2
+If you want to login with your system accounts on the web browser, run \fB\fCttyd login\fR\&.
+.IP \(bu 2
+You can even run a none shell command like vim, try: \fB\fCttyd vim\fR, the web browser will show you a vim editor.

+
+.SH SSL how\-to
+.PP
+Generate SSL CA and self signed server/client certificates:
+
+.PP
+.RS
+
+.nf
+# CA certificate (FQDN must be different from server/client)
+openssl genrsa \-out ca.key 4096
+openssl req \-new \-x509 \-days 365 \-key ca.key \-out ca.crt
+# server certificate
+openssl req \-newkey rsa:2048 \-nodes \-keyout server.key \-out server.csr
+openssl x509 \-req \-days 365 \-in server.csr \-CA ca.crt \-CAkey ca.key \-set\_serial 01 \-out server.crt
+# client certificate (the p12/pem format may be useful for some clients)
+openssl req \-newkey rsa:2048 \-nodes \-keyout client.key \-out client.csr
+openssl x509 \-req \-days 365 \-in client.csr \-CA ca.crt \-CAkey ca.key \-set\_serial 02 \-out client.crt

+openssl pkcs12 \-in client.p12 \-out client.pem \-clcerts
+
+.fi
+.RE
+

+Then start ttyd:

+
+.nf
+ttyd \-\-ssl \-\-ssl\-cert server.crt \-\-ssl\-key server.key \-\-ssl\-ca ca.crt bash
+
+.fi
+.RE
+

+You may want to test the client certificate verification with \fIcurl\fP(1):

+curl \-\-insecure \-\-cert client.p12[:password] \-v https://localhost:7681
+
+.fi
+.RE
+
+.PP
+If you don't want to enable client certificate verification, remove the \fB\fC\-\-ssl\-ca\fR option.
+
+
+.SH Docker and ttyd
+.PP
+Docker containers are jailed environments which are more secure, this is useful for protecting the host system, you may use ttyd with docker like this:
+.IP \(bu 2
+Sharing single docker container with multiple clients: docker run \-it \-\-rm \-p 7681:7681 tsl0922/ttyd.
+.IP \(bu 2
+Creating new docker container for each client: ttyd docker run \-it \-\-rm ubuntu.

+# Examples

+```  
+ttyd -p 8080 bash -x

+  - If you want to login with your system accounts on the web browser, run `ttyd login`.

+  - Sharing single process with multiple clients: `ttyd tmux new -A -s ttyd vim`, run `tmux new -A -s ttyd` to connect to the tmux session from terminal.
+
+# SSL how-to
+  Generate SSL CA and self signed server/client certificates:
+
+```
+# CA certificate (FQDN must be different from server/client)
+openssl genrsa -out ca.key 4096
+openssl req -new -x509 -days 365 -key ca.key -out ca.crt
+# server certificate

+openssl pkcs12 -export -clcerts -in client.crt -inkey client.key -out client.p12
+openssl pkcs12 -in client.p12 -out client.pem -clcerts
+```
+
+  Then start ttyd:
+
+```
+ttyd --ssl --ssl-cert server.crt --ssl-key server.key --ssl-ca ca.crt bash
+```
+
+  You may want to test the client certificate verification with *curl*(1):
+
+```
+curl --insecure --cert client.p12[:password] -v https://localhost:7681
+```
+
+  If you don't want to enable client certificate verification, remove the `--ssl-ca` option.
+
+# Docker and ttyd
+  Docker containers are jailed environments which are more secure, this is useful for protecting the host system, you may use ttyd with docker like this:
+
+  - Sharing single docker container with multiple clients: docker run -it --rm -p 7681:7681 tsl0922/ttyd.
+  - Creating new docker container for each client: ttyd docker run -it --rm ubuntu.
