Yopass - Share Secrets Securely
Yopass is a project for sharing secrets in a quick and secure manner*. The sole purpose of Yopass is to minimize the amount of passwords floating around in ticket management systems, Slack messages and emails. The message is encrypted/decrypted locally in the browser and then sent to yopass without the decryption key which is only visible once during encryption, yopass then returns a one-time URL with 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 on security. There's no mapping between the generated UUID and the user that submitted the encrypted message. It's always best send all the context except password over another channel.
Demo available here. It's recommended to host yopass yourself if you care about security.
- End-to-End encryption using OpenPGP
- 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
Yopass was first released in 2014 and has since then been maintained by me and contributed to by this fantastic group of contributors. Yopass is used by many large corporations which of which none are currently listed in this readme. If you are using yopass and want to support other then by code contributions. Give your thanks in an email, consider donating or by giving consent to list your company name as a user of Yopass in this readme(Trusted by)
The main motivation of Yopass is to make it easy for everyone to share secrets easily and quickly via a simple webinterface. Nevertheless, a command-line interface is provided as well to support use cases where the output of a program needs to be shared.
$ 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/#/...

The following options are currently available to install the CLI locally.
Compile from source (needs Go >= v1.15)
export GO111MODULE=on && go get github.com/jhaals/yopass/cmd/yopass && go install github.com/jhaals/yopass/cmd/yopass
Arch Linux (AUR package)
yay -S yopass
Installation / Configuration
Here are the server configuration options.
Command line flags:
$ 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
Encrypted secrets can be stored either in Memcached or Redis by changing the
Use the Docker Compose file
deploy/with-nginx-and-letsencrypt/docker-compose.yml to set up a yopass instance with TLS transport encryption and certificate auto renewal using Let's Encrypt. First point your domain to the host you want to run yopass on. Then replace the placeholder values for
deploy/with-nginx-and-letsencrypt/docker-compose.yml with your values. Afterwards change the directory to
deploy/with-nginx-and-letsencrypt and start the containers with:
docker-compose up -d
Yopass will then be available under the domain you specified through
Advanced users that already have a reverse proxy handling TLS connections can use the
cd deploy/docker/compose/insecure docker-compose up -d
Afterwards point your reverse proxy to
With TLS encryption
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
Afterwards yopass will be available on port 443 through all IP addresses of the host, including public ones. If you want to limit the availability to a specific IP address use
-p like so:
Without TLS encryption (needs a reverse proxy for transport encryption):
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
Afterwards point your reverse proxy that handles the TLS connections to
Yopass website is a separate component in this step which can be deployed to netlify for free.
You can run Yopass on AWS Lambda backed by dynamodb
cd deploy/aws-lambda && ./deploy.sh
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.
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
- 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)
Yopass has third party support for other languages. That means you can write translations for the language you'd like or use a third party language file. Please note that yopass itself is english only and any other translations are community supported.
