SSHL/SSLH is a VPN app that can tunnel SSH via DNS SSL HTTP and SOCKS Proxies. This app lets you send customized HTTP Request Message to the server.

What are the advantages on using this app?
1. Minimalistic no exaggerations
2. Low RAM usage.
3. Low Battery usage.
4. File size is under 1 mb

Troubleshooting

Connected but cannot browse?
You can try to remove DNS from route by un-toggling include_dns.

DNS Leaking?
Un-toggling include_dns will prevent DNS leaks.

Routing
[Address]SLASH[Length]SPACE[Address]SLASH[Length]

Where;
SLASH = / is a delimiter of [Address] = IP Address
[Length] = Prefix Length
SPACE = is a delimiter of routes.

e.g. 1.1.1.1/32 8.8.8.8/32


HTTP Message Generator Syntax

[request_line] = CONNECT[sp][request_uri][sp]HTTP/1.0[crlf][crlf]
[request_uri] = [userfinfo]@[authority]
[userfinfo] = [http_username][c][http_password]
[authority] = [host][c][port]
[http_username] = http proxy username
[http_password] = http proxy password
[host] = ssh remote host
[port] = ssh remote port
[crlf] = Carriage Return (US-ASCII 13 r) Line Feed (US-ASCII 10 n)
[lf] = Line Feed (US-ASCII 10 n)
[cr] = Carriage Return (US-ASCII 13 r)

[ff] = Form Feed (FF) character (0x0C f)

[sp] = US-ASCII SP space character (32)

[c] = Colon (US-ASCII 58 :)

[eol] = (End of Line) Carriage Return (US-ASCII 13 r) Line Feed (US-ASCII 10 n)

String Split and Collection - Manipulation
[shuffle] = works by randomly permuting the specified list elements.
[reverse] = It reverses the order of elements in a list passed as an argument.
[rotate] = is used to rotate the elements present in the specified list of Collection by a given distance.
[split] = is used for splitting a String into its substrings based on the given delimiter or regular expression.
[delay_split] = is used for splitting a string which is delayed by a Thread (1000ms * number of delimiter).
[""] = do nothing.


The two Generator Buttons
Traditional (left) and the Simplified (right).
Those buttons will assist you in creating customized HTTP Request Message to the server examples are given by tapping the dropdown arrows in the text fields.


NB: When using HTTP Proxy with username and password a Proxy-Authorization Request Header will be generated automatically after tapping the Generate button.

- "show_*" (toggle to allow recipients to show all crucial information from config file)
- "lock_type" locks the proxy type.
- "lock_ports" locks the ports.
- "file_name" the file name of the config.
- "expiry" the expiry date of the config.
