simp_le

Build Status

Simple Let’s Encrypt client.

simp_le --email you@example.com -f account_key.json \
  -f fullchain.pem -f key.pem \
  -d example.com -d www.example.com --default_root /var/www/html \
  -d example.net:/var/www/other_html

For more info see simp_le --help.

Manifest

  1. UNIX philosophy: Do one thing and do it well!
  2. simp_le --valid_min ${seconds?} -f cert.pem implies that cert.pem is valid for at at least valid_min. Register new ACME CA account if necessary. Issue new certificate if no previous key/certificate/chain found. Renew only if necessary.
  3. (Sophisticated) “manager” for ${webroot?}/.well-known/acme-challenge only. No challenges other than http-01. Existing web-server must be running already.
  4. No magical webserver auto-configuration.
  5. Owner of ${webroot?}/.well-known/acme-challenge must be able to run the script, without privilege escalation (sudo, root, etc.).
  6. crontab friendly: fully automatable - no prompts, etc.
  7. No configuration files. CLI flags as the sole interface! Users should write their own wrapper scripts or use shell aliases if necessary.
  8. Support multiple domains with multiple roots. Always create single SAN certificate per simp_le run.
  9. Flexible storage capabilities. Built-in simp_le -f fullchain.pem -f key.pem, simp_le -f chain.pem -f cert.pem -f key.pem, etc. Extensions through simp_le -f external.sh.
  10. Do not allow specifying output file paths. Users should symlink if necessary!
  11. No need to allow specifying an arbitrary command when renewal has happened, just check the exit code:
    • 0 if certificate data was created or updated;
    • 1 if renewal not necessary;
    • 2 in case of errors.
  12. --server (support multiple CAs).
  13. Support for revocation.
