A new Slack extension promises to let you send memes to your coworkers in peace.
Aptly called 'Shhlack,' the tool allows you encrypt and decrypt messages 'on the fly' so that only the sender and the receiver are able to read them.
Shhlack was created by information security company MindedSecurity and can be installed as a web browser extension or as an add-on to the Slack app.

Information security company MindedSecurity created a tool called 'Shhlack' that allows you to encrypt messages sent on Slack. Only the sender and the receiver are able to view them
Slack is used by millions of employees as a messaging app in the workplace.
The tool relies on pre-shared keys, or passwords, that are exchanged between users.
However, it's recommended that you send someone a pre-shared key outside of Slack, as doing it in the app defeats the purpose of establishing a secret message.
After Shhlack is installed, users can begin an encrypted message by clicking on a colorful lock icon that appears next to the dialog box in Slack.
They can also hold down the Alt and S keys to open an encrypted exchange.
Slack servers and Slack Bots won't be able to see any messages in clear text, according to MindedSecurity.

Only users and bots that have the correct pre-shared key will be able to view unencrypted content. For users who don't have the key, messages will show up as gibberish
Only users and bots that have the correct pre-shared key will be able to view unencrypted content.
For people without the pre-shared key, any encrypted messages will show up as 'encoded garbage', the firm added.
The tool also works in group chats with other users.
For example, if only two users in the group have been notified of the pre-shared key, they'll be the only two people who can view encrypted messages.
Users with the passkey will see messages that are labeled 'Encrypted: (First Passphrase)' and in a distinctive dialog box.
Again, all other users in the chat will see gibberish if someone sends an encrypted message to the group.
Shhlack also supports multiple keys so that users can have more than one key that can be shared with other users, MindedSecurity noted
Software firm Slack has rolled out the ability for the owner of the Slack network (the boss) to gather all data from other users (employees).
For the Plus and Enterprise Grid plans, the feature is now automatically included.
