Security
If you access semaphore over http, and input a private key, that's rather unsecure. So either put a https proxy in front, or do this over a trusted network.
For security reasons, you should use Semaphore via:
- VPN
- SSL
Use this option if the Semaphore server is located in a private network.
Semaphore doesn't support SSL. You should use an NGINX, or an Apache web server in front of Semaphore to serve secure connections.
NGINX server configuration example:
server {
listen 443 ssl;
server_name _;
# add Strict-Transport-Security to prevent man in the middle attacks
add_header Strict-Transport-Security "max-age=31536000" always;
# SSL
ssl_certificate /etc/nginx/cert/cert.pem;
ssl_certificate_key /etc/nginx/cert/privkey.pem;
# Recommendations from
# https://raymii.org/s/tutorials/Strong_SSL_Security_On_nginx.html
ssl_protocols TLSv1.1 TLSv1.2;
ssl_ciphers 'EECDH+AESGCM:EDH+AESGCM:AES256+EECDH:AES256+EDH';
ssl_prefer_server_ciphers on;
ssl_session_cache shared:SSL:10m;
# required to avoid HTTP 411: see Issue #1486

Sensitive data is stored in the database, in an encrypted form. You should set the configuration option
access_key_encryption in configuration file to enable Access Keys encryption. It must be generated by command:head -c32 /dev/urandom | base64
