 * **Bash** - It runs on virtually all unix machines, including BSD, most Linux distributions, MAC OSX.
-* **Get certificates for remote servers** - The tokens used to provide validation of domain ownership, and the certificates themselves can be automatically copied to remote servers (via ssh, sftp or ftp for tokens). The script doesn't need to run on the server itself. This can be useful if you don't have access to run such scripts on the server itself, as it's a shared server for example.

 * **Runs as a daily cron** - so certificates will be automatically renewed when required.

 * **Checks certificates are correctly loaded**. After installation of a new certificate it will test the port specified ( see [Server-Types](#server-types) for options ) that the certificate is actually being used correctly.

+Usage: `getssl -r path/to/cert path/to/key [CA_server]`
 
 You need to specify both the certificate you want to revoke, and the account or private domain key which was used to sign / obtain the original certificate.  The CA_server is an optional parameter and defaults to Let's Encrypt ( "https://acme-v01.api.letsencrypt.org" ) as that is currently the only Certificate Authority using the ACME protocol.

+## Elliptic curve keys
 You can use Elliptic curve keys for both the account key and the domain key (different of course, don't use the same key for both). prime256v1 (NIST P-256) and secp384r1 (NIST P-384) are both fully supported.  secp521r1 (NIST P-521) is included in the code, but not currently supported by Let's Encrypt).
