base on Secure sharing of secrets, passwords and files  # Yopass - Share Secrets Securely [](https://goreportcard.com/report/github.com/jhaals/yopass) [](https://codecov.io/gh/jhaals/yopass)   Yopass is a project for sharing secrets in a quick and secure manner. The sole purpose of Yopass is to minimize passwords floating around in ticket management systems, Slack messages, and emails. Messages are encrypted/decrypted locally in the browser and sent to Yopass without the decryption key, which is only visible once during encryption. Yopass then returns a one-time URL with a specified expiry date. There is no perfect way of sharing secrets online, and there is a trade-off in every implementation. Yopass is designed to be as simple and "dumb" as possible without compromising security. There's no mapping between the generated UUID and the user who submitted the encrypted message. It's always best to send all context except the password over another channel. **[Demo available here](https://yopass.se)**. It's recommended to host yopass yourself if you care about security. - End-to-End encryption using [OpenPGP](https://openpgpjs.org/) - Secrets can only be viewed once - No accounts or user management required - Secrets self destruct after X hours - Custom password option - Limited file upload functionality ## History Yopass was first released in 2014 and has since been maintained by me and contributed to by this fantastic group of [contributors](https://github.com/jhaals/yopass/graphs/contributors). Yopass is used by many large corporations, some of which are listed below. If you are using Yopass and want to support the project beyond code contributions, you can give thanks via email, consider donating, or give consent to list your company name as a user of Yopass in this readme. ## Trusted by - [Doddle LTD](https://doddle.com) - [Spotify](https://spotify.com) - [Gumtree Australia](https://www.gumtreeforbusiness.com.au/) ## Command-line interface The main motivation of Yopass is to make it easy for everyone to share secrets quickly via a simple web interface. A command-line interface is also provided to support use cases where program output needs to be shared. ```console $ yopass --help Yopass - Secure sharing for secrets, passwords and files Flags: --api string Yopass API server location (default "https://api.yopass.se") --decrypt string Decrypt secret URL --expiration string Duration after which secret will be deleted [1h, 1d, 1w] (default "1h") --file string Read secret from file instead of stdin --key string Manual encryption/decryption key --one-time One-time download (default true) --url string Yopass public URL (default "https://yopass.se") Settings are read from flags, environment variables, or a config file located at ~/.config/yopass/defaults.<json,toml,yml,hcl,ini,...> in this order. Environment variables have to be prefixed with YOPASS_ and dashes become underscores. Examples: # Encrypt and share secret from stdin printf 'secret message' | yopass # Encrypt and share secret file yopass --file /path/to/secret.conf # Share secret multiple time a whole day cat secret-notes.md | yopass --expiration=1d --one-time=false # Decrypt secret to stdout yopass --decrypt https://yopass.se/#/... Website: https://yopass.se ``` The following options are currently available to install the CLI locally. - Compile from source (requires Go >= v1.21) ```console go install github.com/jhaals/yopass/cmd/yopass@latest ``` ## Installation / Configuration Here are the server configuration options. Command line flags: ```console $ yopass-server -h --address string listen address (default 0.0.0.0) --database string database backend ('memcached' or 'redis') (default "memcached") --max-length int max length of encrypted secret (default 10000) --memcached string Memcached address (default "localhost:11211") --metrics-port int metrics server listen port (default -1) --port int listen port (default 1337) --redis string Redis URL (default "redis://localhost:6379/0") --tls-cert string path to TLS certificate --tls-key string path to TLS key --cors-allow-origin Access-Control-Allow-Origin CORS setting (default *) --force-onetime-secrets reject non onetime secrets from being created --disable-upload disable the /file upload endpoints --prefetch-secret display information that the secret might be one time use (default true) --disable-features disable features section on frontend --no-language-switcher disable the language switcher in the UI --trusted-proxies strings trusted proxy IP addresses or CIDR blocks for X-Forwarded-For header validation --privacy-notice-url string URL to privacy notice page --imprint-url string URL to imprint/legal notice page ``` Encrypted secrets can be stored either in Memcached or Redis by changing the `--database` flag. ### Proxy Configuration When Yopass is deployed behind a reverse proxy or load balancer (such as Nginx, Caddy, Cloudflare, or AWS ALB), you may want to log the real client IP addresses instead of the proxy's IP. Yopass supports trusted proxy configuration for secure handling of `X-Forwarded-For` headers. **Security Note**: X-Forwarded-For headers are only trusted when requests come from explicitly configured trusted proxies. This prevents IP spoofing from untrusted sources. #### Examples: ```bash # Trust a single proxy IP yopass-server --trusted-proxies 192.168.1.100 # Trust multiple proxy IPs yopass-server --trusted-proxies 192.168.1.100,10.0.0.50 # Trust proxy subnets (CIDR notation) yopass-server --trusted-proxies 192.168.1.0/24,10.0.0.0/8 # Environment variable (useful for Docker) export TRUSTED_PROXIES="192.168.1.0/24,10.0.0.0/8" yopass-server ``` #### Common Proxy Scenarios: - **Nginx/Apache**: Use the IP address of your reverse proxy server - **Cloudflare**: Use Cloudflare's IP ranges (available from their documentation) - **AWS ALB/ELB**: Use your VPC's CIDR block or the load balancer's subnet - **Docker networks**: Use the Docker network's gateway IP or subnet Without trusted proxies configured, Yopass will always use the direct connection IP for security, which is the recommended default behavior. ### Docker Compose Use the Docker Compose file `deploy/with-nginx-proxy-and-letsencrypt/docker-compose.yml` to set up a Yopass instance with TLS transport encryption and automatic certificate renewal using [Let's Encrypt](https://letsencrypt.org/). First, point your domain to the host where you want to run Yopass. Then replace the placeholder values for `VIRTUAL_HOST`, `LETSENCRYPT_HOST`, and `LETSENCRYPT_EMAIL` in the docker-compose.yml file with your values. Change to the deployment directory and start the containers: ```console docker-compose up -d ``` Yopass will then be available under the domain you specified through `VIRTUAL_HOST` / `LETSENCRYPT_HOST`. Advanced users who already have a reverse proxy handling TLS connections can use the `insecure` setup: ```console cd deploy/docker-compose/insecure docker-compose up -d ``` Then point your reverse proxy to `127.0.0.1:80`. ### Docker With TLS encryption ```console docker run --name memcached_yopass -d memcached docker run -p 443:1337 -v /local/certs/:/certs \ --link memcached_yopass:memcached -d jhaals/yopass --memcached=memcached:11211 --tls-key=/certs/tls.key --tls-cert=/certs/tls.crt ``` Yopass will then be available on port 443 through all IP addresses of the host, including public ones. To limit availability to a specific IP address, use `-p 127.0.0.1:443:1337`. Without TLS encryption (needs a reverse proxy for transport encryption): ```console docker run --name memcached_yopass -d memcached docker run -p 127.0.0.1:80:1337 --link memcached_yopass:memcached -d jhaals/yopass --memcached=memcached:11211 ``` Then point your reverse proxy that handles TLS connections to `127.0.0.1:80`. ### Kubernetes ```console kubectl apply -f deploy/yopass-k8.yaml kubectl port-forward service/yopass 1337:1337 ``` _This is meant to get you started, please configure TLS when running yopass for real._ ## Monitoring Yopass optionally provides metrics in the [OpenMetrics][] / [Prometheus][] text format. Use flag `--metrics-port <port>` to let Yopass start a second HTTP server on that port making the metrics available on path `/metrics`. Supported metrics: - Basic [process metrics][] with prefix `process_` (e.g. CPU, memory, and file descriptor usage) - Go runtime metrics with prefix `go_` (e.g. Go memory usage, garbage collection statistics, etc.) - HTTP request metrics with prefix `yopass_http_` (HTTP request counter, and HTTP request latency histogram) [openmetrics]: https://openmetrics.io/ [prometheus]: https://prometheus.io/ [process metrics]: https://prometheus.io/docs/instrumenting/writing_clientlibs/#process-metrics ## Translations Yopass accepts translations for additional languages. The modern frontend includes built-in internationalization support using react-i18next, with English and Swedish currently available.
