### 3proxy SSL/TLS plugin

Plugin can be used to transparently decypher SSL/TLS data and TLS encryption for proxy traffic.

#### For transparent certificate spoofing:

ssl_mitm - spoof certificates for services started below. Usage without ssl_client_verify is insecure.
ssl_nomitm - do not spoof certificates for services started below

#### To protect traffic to server (https:// proxy) - since 0.9.5 version

ssl_serv - require TLS connection for services below
ssl_noserv - do not require TLS connection for services below Parameters:
ssl_server_cert /path/to/cert - Server certificate (should not be selfsigned and must contain Alternative name) for ssl_serv
ssl_server_key /path/to/key - Server ceritifacte key for ssl_server_cert or generated mitm certificate
ssl_client_ciphersuites ciphersuites_list - TLS client ciphers for TLS 1.3, e.g. ssl_client_ciphersuites TLS_AES_128_GCM_SHA256
ssl_server_ciphersuites ciphersuites_list - TLS server ciphers for TLS 1.3
ssl_client_cipher_list ciphersuites_list - TLS client ciphers for TLS 1.2 and below , e.g. ssl_client_cipher_list ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:DHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384:DHE-RSA-CHACHA20-POLY1305
ssl_server_cipher_list ciphersuites_list - TLS server ciphers for TLS 1.2 and below
ssl_client_min_proto_version tls_version - TLS client min TLS version (e.g. TLSv1.2)
ssl_server_min_proto_version tls_version - TLS server min TLS version (e.g. TLSv1.2)
ssl_client_max_proto_version tls_version - TLS client max TLS version (e.g. TLSv1.2)
ssl_server_max_proto_version tls_version - TLS server max TLS version (e.g. TLSv1.2)
ssl_client_verify - verify certificate for upstream server in TLS client functionality (used with ssl_mitm)
ssl_client_no_verify - do not verify certificate for upstream server in TLS client functionality (default)
ssl_server_ca_file /path/to/cafile - CA certificate file for mitm
ssl_server_ca_key /path/to/cakey - key for ssl_server_ca_file mitm CA
ssl_client_ca_file, ssl_client_ca_dir, ssl_client_ca_store - locations for root CAs used with ssl_client_verify for TLS client
ssl_certcache /path/to/cache/ - location for generated mitm certificates cache, optional, if ssl_server_ca_file / ssl_server_ca_key are configured. Cache may contain 3 files: 3proxy.pem - public self-signed certificates (used if ssl_server_ca_file is not configured), 3proxy.key - key for public certificates, used if ssl_server_ca_keyserver.key is not configured, server.key - this key is used if ssl_server_key is not configured to generates spoofed certificates. If server.key is absent, 3proxy.key is used to generate certificates. Generated certificates are placed to the same path.

#### mitm example:

    plugin /path/to/SslPlugin.dll ssl_plugin
    ssl_server_ca_file /path/to/cafile
    ssl_server_ca_key /path/to/cakey
    ssl_mitm
    proxy -p3128
    ssl_nomitm
    proxy -p3129

mitm's traffic with spoofed ceritifacate for port 3128 proxy.

#### https:// proxy example:

    plugin /path/to/SSLPlugin.so ssl_plugin
    ssl_server_cert path_to_cert
    ssl_server_key path_to_key
    ssl_serv
    proxy -p33128
    ssl_noserv
    proxy -p3128
