Documenso needs a signing certificate to digitally sign documents. For full, up-to-date instructions on generating, converting, and configuring a certificate, see the official documentation:

- [Signing Certificate](https://docs.documenso.com/docs/self-hosting/configuration/signing-certificate): Overview and all certificate options
- [Local Certificate](https://docs.documenso.com/docs/self-hosting/configuration/signing-certificate/local): Generate a self-signed `.p12` certificate with OpenSSL
- [Google Cloud HSM](https://docs.documenso.com/docs/self-hosting/configuration/signing-certificate/google-cloud-hsm): Sign using Google Cloud KMS

For deploying Documenso with Docker, see the [Docker Deployment](https://docs.documenso.com/docs/self-hosting/deployment/docker) and [Docker Compose](https://docs.documenso.com/docs/self-hosting/deployment/docker-compose) guides.
