# Signing Commits
Signing a commit means adding a digital signature to your commits.
This allows someone who has your certificate to verify that you made
the signature. Signing commits is a prerequisite to using `sq-git`.
If you are using Sequoia, you can create a certificate as follows:
```shell
$ sq key generate --name "Iliana" --email iliana@example.org --own-key
Please enter the password to protect key (press enter to not use a password):
Please repeat the password:
- ┌ 5D4142463C04ADCF7372231DC06A1E7BD5E115DC
└ Iliana
- certification created
- ┌ 5D4142463C04ADCF7372231DC06A1E7BD5E115DC
└ <iliana@example.org>
- certification created
...
```
Then you need to configure `git` to use it:
```shell
$ git config --global gpg.gpgsign true
$ git config --global user.signingKey 5D4142463C04ADCF7372231DC06A1E7BD5E115DC
```
