Keep passwords and other sensitive information out of your inboxes and chat logs.
A one-time secret is a link that can be viewed only once. A single-use URL.
When you send people sensitive info like passwords and private links via email or chat, there are copies of that information stored in many places. If you use a one-time link instead, the information persists for a single viewing which means it can't be read by someone else later. This allows you to send sensitive information in a safe way knowing it's seen by one person only. Think of it like a self-destructing message.

The instructions above suggest cloning via the https
URI. You can also clone using the SSH URI if you have a github account (which is generally more convenient, but specific to github).
With a github account
ssh -T [email protected]
Hi delano! You've successfully authenticated, but GitHub does not provide shell access.
Without a github account
ssh -T [email protected]
Warning: Permanently added the RSA host key for IP address '0.0.0.0/0' to the list of known hosts.

NOTE: you can also use the etc directory from here instead of copying it to the system. Just be sure to secure the permissions on it

- Update your secret key
- Store it in your password manager because it's included in the secret encryption
- Add or remove locales
- Update the SMTP or SendGrid credentials
- Update the from address
- it's used for all sent emails
- Update the the limits at the bottom of the file
- These numbers refer to the number of times each action can occur for unauthenticated users.
- If you would like to increase the limits for authenticated users too, see (lib/onetime.rb](https://github.com/onetimesecret/onetimesecret/blob/main/lib/onetime.rb#L261-L279)
/etc/onetime/redis.conf
- The host, port, and password need to match
/etc/onetime/locale/*
- Optionally you can customize the text used throughout the site and emails
- You can also edit the
:broadcast
string to display a brief message at the top of every page
There are many way to run the webapp, just like any Rack-based app. The default web server we use is thin.
To run locally:
bundle exec thin -e dev -R config.ru -p 7143 start
To run on a server:
bundle exec thin -d -S /var/run/thin/thin.sock -l /var/log/thin/thin.log -P /var/run/thin/thin.pid -e prod -s 2 restart
To run with docker:
docker compose up
open http://localhost:3000/
We include a global secret in the encryption key so it needs to be long and secure. One approach for generating a secret:
dd if=/dev/urandom bs=20 count=1 | openssl sha256
