Encrypting Channels
You can encrypt channels or conversations to ensure that messages remain secure and inaccessible to others, including administrators.
To use encryption, you need to configure a passphrase. Passphrases are used for channel encryption and will not be stored on the server.
To set your passphrase:
- Click Account > Encryption > Set passphrase.
- You can download the private key in case you forget the passphrase in the future.
- Now you can create an encrypted channel or conversation.
To create encrypted channels:
- Click the add icon in the left column next to CHANNELS.
- Click Create.
- Select Private Channel and Encrypted.
- Enter the channel name and details. Click Create.
To create encrypted conversations:
- Click the add icon in the left column next to CONVERSATIONS.
- Select the members to include in the conversation.
- Select Encrypt conversation and click Chat.
To decrypt channels or conversations:
- You can decrypt using the following methods:
- Click Account > Encryption > Decrypt channels.
- Click on an encrypted channel or conversation.
- You'll be prompted to enter your passphrase or upload the private key.
To change your passphrase:
- Click Account > Encryption > Change passphrase.
- After resetting your passphrase, you'll need to rejoin all encrypted channels. Ask other members to help you regain access to these channels.
To renew your private key:
- Click Account > Encryption > Renew private key.
- Enter your passphrase.
Note:
- Public channels can't be encrypted.
- HTTPS is required for encrypted channels.
- The maximum file upload size for an encrypted channel and conversation is 32 MB.
- When creating an encrypted channel or conversation, you can only invite members who have configured a passphrase.
- Decryption is required every time you refresh the browser.
- Indexing services are deactivated in encrypted channels and conversations. This includes mentions, hashtags, Open Graphic for URLs, search, icon previews, slash commands, bots, and webhooks.
- If encryption is deactivated by an administrator, encrypted channels and conversations become deactivated and closed, and new encrypted channels or conversations can't be created.
- Decryption is only available if you have encrypted channels or conversations.
