Sharing sensitive data with Chalk
true

Overview

If you need to send sensitive material to Chalk, you can use asymmetric encryption to transmit your data securely. Only Chalk will be able to view the data that you encrypt with Chalk's public key.

Using GnuPG

To begin, ensure that you've installed GnuPG (Mac, Ubuntu). GnuPG provides the gpg utility, which you will use to encrypt your data using Chalk's public key.

Next, download and import Chalk's public key:

curl -s https://docs.chalk.ai/chalk-public-key.key > chalk-public-key.key
gpg --import chalk-public-key.key

Next, encrypt your plaintext using Chalk's public key:

cat <plaintext_file> | gpg -e -r Chalk > ciphertext.gpg

Now you can transmit ciphertext.gpg via email or Slack to Chalk. Only Chalk's support staff will be able to decrypt and view the contents of ciphertext.gpg.
