Pretty Secure Secret Transmissions. WordPress plugin to share encrypted expiring posts. This plugin is inspired by the great onetimesecret.com though it does not share any codebase
When you share a link with someone in Slack, the encrypted secret will be displayed to the user.
We need to lock down non browser user agents and bots, additionally, we should block the secret from being displayed at all in the previewing or if some one is using Yoast or another SEO tool.
More than likely the meta data is what is being parsed by Slack and other chat apps
