chisel
v1.10.1
Chisel é um túnel TCP/UDP rápido, transportado por HTTP, protegido via SSH. Executável único, incluindo cliente e servidor. Escrito em Go (Golang). O cinzel é principalmente útil para passar pelos firewalls, embora também possa ser usado para fornecer um terminal seguro em sua rede.

sudo dnf -y install chisel$ go install github.com/jpillora/chisel@latest Um aplicativo de demonstração no Heroku está executando este chisel server :
$ chisel server --port $PORT --proxy http://example.com
# listens on $PORT, proxy web requests to http://example.com Este aplicativo de demonstração também está executando um servidor de arquivos simples em :3000 , que normalmente é inacessível devido ao firewall do Heroku. No entanto, se tocarmos com:
$ chisel client https://chisel-demo.herokuapp.com 3000
# connects to chisel server at https://chisel-demo.herokuapp.com,
# tunnels your localhost:3000 to the server's localhost:3000E depois visite localhost: 3000, devemos ver uma listagem de diretórios. Além disso, se visitarmos o aplicativo de demonstração no navegador, devemos atingir o proxy padrão do servidor e ver uma cópia do exemplo.com.

$ chisel server --help
Usage: chisel server [options]
Options:
--host, Defines the HTTP listening host – the network interface
(defaults the environment variable HOST and falls back to 0.0.0.0).
--port, -p, Defines the HTTP listening port (defaults to the environment
variable PORT and fallsback to port 8080).
--key, (deprecated use --keygen and --keyfile instead)
An optional string to seed the generation of a ECDSA public
and private key pair. All communications will be secured using this
key pair. Share the subsequent fingerprint with clients to enable detection
of man-in-the-middle attacks (defaults to the CHISEL_KEY environment
variable, otherwise a new key is generate each run).
--keygen, A path to write a newly generated PEM-encoded SSH private key file.
If users depend on your --key fingerprint, you may also include your --key to
output your existing key. Use - (dash) to output the generated key to stdout.
--keyfile, An optional path to a PEM-encoded SSH private key. When
this flag is set, the --key option is ignored, and the provided private key
is used to secure all communications. (defaults to the CHISEL_KEY_FILE
environment variable). Since ECDSA keys are short, you may also set keyfile
to an inline base64 private key (e.g. chisel server --keygen - | base64).
--authfile, An optional path to a users.json file. This file should
be an object with users defined like:
{
"<user:pass>": ["<addr-regex>","<addr-regex>"]
}
when <user> connects, their <pass> will be verified and then
each of the remote addresses will be compared against the list
of address regular expressions for a match. Addresses will
always come in the form "<remote-host>:<remote-port>" for normal remotes
and "R:<local-interface>:<local-port>" for reverse port forwarding
remotes. This file will be automatically reloaded on change.
--auth, An optional string representing a single user with full
access, in the form of <user:pass>. It is equivalent to creating an
authfile with {"<user:pass>": [""]}. If unset, it will use the
environment variable AUTH.
--keepalive, An optional keepalive interval. Since the underlying
transport is HTTP, in many instances we'll be traversing through
proxies, often these proxies will close idle connections. You must
specify a time with a unit, for example '5s' or '2m'. Defaults
to '25s' (set to 0s to disable).
--backend, Specifies another HTTP server to proxy requests to when
chisel receives a normal HTTP request. Useful for hiding chisel in
plain sight.
--socks5, Allow clients to access the internal SOCKS5 proxy. See
chisel client --help for more information.
--reverse, Allow clients to specify reverse port forwarding remotes
in addition to normal remotes.
--tls-key, Enables TLS and provides optional path to a PEM-encoded
TLS private key. When this flag is set, you must also set --tls-cert,
and you cannot set --tls-domain.
--tls-cert, Enables TLS and provides optional path to a PEM-encoded
TLS certificate. When this flag is set, you must also set --tls-key,
and you cannot set --tls-domain.
--tls-domain, Enables TLS and automatically acquires a TLS key and
certificate using LetsEncrypt. Setting --tls-domain requires port 443.
You may specify multiple --tls-domain flags to serve multiple domains.
The resulting files are cached in the "$HOME/.cache/chisel" directory.
You can modify this path by setting the CHISEL_LE_CACHE variable,
or disable caching by setting this variable to "-". You can optionally
provide a certificate notification email by setting CHISEL_LE_EMAIL.
--tls-ca, a path to a PEM encoded CA certificate bundle or a directory
holding multiple PEM encode CA certificate bundle files, which is used to
validate client connections. The provided CA certificates will be used
instead of the system roots. This is commonly used to implement mutual-TLS.

$ chisel client --help
Usage: chisel client [options] <server> <remote> [remote] [remote] ...
<server> is the URL to the chisel server.
<remote>s are remote connections tunneled through the server, each of
which come in the form:
<local-host>:<local-port>:<remote-host>:<remote-port>/<protocol>
■ local-host defaults to 0.0.0.0 (all interfaces).
■ local-port defaults to remote-port.
■ remote-port is required*.
■ remote-host defaults to 0.0.0.0 (server localhost).
■ protocol defaults to tcp.
which shares <remote-host>:<remote-port> from the server to the client
as <local-host>:<local-port>, or:
R:<local-interface>:<local-port>:<remote-host>:<remote-port>/<protocol>
which does reverse port forwarding, sharing <remote-host>:<remote-port>
from the client to the server's <local-interface>:<local-port>.

stdio:example.com:22
1.1.1.1:53/udp
When the chisel server has --socks5 enabled, remotes can
specify "socks" in place of remote-host and remote-port.
The default local host and port for a "socks" remote is
127.0.0.1:1080. Connections to this remote will terminate
at the server's internal SOCKS5 proxy.
When the chisel server has --reverse enabled, remotes can
be prefixed with R to denote that they are reversed. That
is, the server will listen and accept connections, and they
will be proxied through the client which specified the remote.
Reverse remotes specifying "R:socks" will listen on the server's
default socks port (1080) and terminate the connection at the
client's internal SOCKS5 proxy.
When stdio is used as local-host, the tunnel will connect standard
input/output of this program with the remote. This is useful when
combined with ssh ProxyCommand. You can use
ssh -o ProxyCommand='chisel client chiselserver stdio:%h:%p'
[email protected]
to connect to an SSH server through the tunnel.
Options:
--fingerprint, A *strongly recommended* fingerprint string
to perform host-key validation against the server's public key.
Fingerprint mismatches will close the connection.
Fingerprints are generated by hashing the ECDSA public key using
SHA256 and encoding the result in base64.
Fingerprints must be 44 characters containing a trailing equals (=).
--auth, An optional username and password (client authentication)
in the form: "<user>:<pass>". These credentials are compared to
the credentials inside the server's --authfile. defaults to the
AUTH environment variable.
--keepalive, An optional keepalive interval. Since the underlying
transport is HTTP, in many instances we'll be traversing through
proxies, often these proxies will close idle connections. You must
specify a time with a unit, for example '5s' or '2m'. Defaults
to '25s' (set to 0s to disable).
--max-retry-count, Maximum number of times to retry before exiting.
Defaults to unlimited.
--max-retry-interval, Maximum wait time before retrying after a
disconnection. Defaults to 5 minutes.
--proxy, An optional HTTP CONNECT or SOCKS5 proxy which will be
used to reach the chisel server. Authentication can be specified
inside the URL.
For example, http://admin:[email protected]:8081
or: socks://admin:[email protected]:1080
--header, Set a custom header in the form "HeaderName: HeaderContent".
Can be used multiple times. (e.g --header "Foo: Bar" --header "Hello: World")
--hostname, Optionally set the 'Host' header (defaults to the host
found in the server url).
--sni, Override the ServerName when using TLS (defaults to the
hostname).
--tls-ca, An optional root certificate bundle used to verify the
chisel server. Only valid when connecting to the server with
"https" or "wss". By default, the operating system CAs will be used.
--tls-skip-verify, Skip server TLS certificate verification of
chain and host name (if TLS is used for transport connections to
server). If set, client accepts any TLS certificate presented by
the server and any host name in that certificate. This only affects
transport https (wss) connection. Chisel server's public key
may be still verified (see --fingerprint) after inner connection
is established.
--tls-key, a path to a PEM encoded private key used for client
authentication (mutual-TLS).
--tls-cert, a path to a PEM encoded certificate matching the provided
private key. The certificate must have client authentication
enabled (mutual-TLS).

A criptografia está sempre ativada. Quando você inicia um servidor de cinzel, ele gera um par de chaves públicas/privadas da ECDSA na memória. A impressão digital de chave pública (Base64 codificada SHA256) será exibida à medida que o servidor inicia. Em vez de gerar uma chave aleatória, o servidor pode opcionalmente especificar um arquivo -chave, usando a opção --keyfile . Quando os clientes se conectarem, eles também exibirão a impressão digital pública do servidor. O cliente pode forçar uma impressão digital específica usando a opção --fingerprint . Veja o --help acima para obter mais informações.
Usando a opção --authfile , o servidor pode opcionalmente fornecer um arquivo de configuração user.json para criar uma lista de usuários aceitos. O cliente então autentica usando a opção --auth . Consulte o users.json para um exemplo de arquivo de configuração de autenticação. Veja o --help acima para obter mais informações.
Internamente, isso é feito usando o método de autenticação de senha fornecido pelo SSH. Saiba mais sobre crypto/ssh aqui http://blog.gopheracademy.com/go-andsh/.
Imprima uma nova chave privada para o terminal
chisel server --keygen -
# or save it to disk --keygen /path/to/mykeyInicie seu servidor de cinzel
jpillora/chisel server --keyfile ' <ck-base64 string or file path> ' -p 9312 --socks5Conecte seu cliente cinzel (usando a impressão digital do servidor)
chisel client --fingerprint ' <see server output> ' < server-address > :9312 socksAponte seus clientes Socks5 (por exemplo, OS/navegador) para:
<client-address>:1080
Agora você tem uma conexão Socks5 criptografada e autenticada sobre HTTP
