Add man pages Documentation is a crucial point for every project, and the most effective and traditional way to document a program is to write man page. Here, the mdoc is used because it is simple. Because the documentation is quite different from the project itself, the man pages and others helpful files are distributed under a different license. For this usage, the GNU All-Permissive License is adequate. https://www.gnu.org/prep/maintain/html_node/License-Notices-for-Other-Files.html man 7 groff_mdoc

Allow to reuse a key pair instead of creating a new one at each renewal The default behavior of most ACME clients is to generate a new key pair at each renewal. While this choice is respectable and perfectly justified in most configuration, it is also quite incompatible with the use of HTTP Public Key Pinning (HPKP). Although HPKP is not wildly supported and sometimes deprecated, users wishing to use it should not be blocked. https://tools.ietf.org/html/rfc7469 https://en.wikipedia.org/wiki/HTTP_Public_Key_Pinning

Stop to require the `orders` field on account creation RFC 8555 states that: - when an account is successfully created, the server "returns this account object" (section 7.3); - the `orders` field in account objects is mandatory (section 7.1.2). Despite that, Boulder does not returns the `orders` field when an account is created. This non-standard behavior prevented ACMEd from creating account and testing them for existence. In order to allow ACMEd to retrieve certificates from CAs using Boulder, the `orders` field is no longer mandatory and the account existence is tested when the order is requested. https://github.com/letsencrypt/boulder/issues/3335

ACMEd v0.11.0
4 years ago
Refactor the account management Until now, the account management was archaic and it was impossible to improve it without this heavy refactoring. Accounts are now disjoint from both certificates and endpoints. They have their own hooks and their own environment variables. They are stored in a binary file instead of the PEM exports of the private and public keys. This refactoring will allow account management to evolve into something more serious, with real key rollover, contact information update and so on.

Refactor the certificate key type management The previous system used a duplicated enum (`acmed::certificate::Algorithm`) and an imprecise identifier name (algorithm) for both the certificate configuration and post operation hook variable. The first one has been replaced by the `acme_common::crypto::KeyType` enum and the second renames `key_type`.

Allow to give a file path in a hook's stdin There is use-cases where a command's standard input should be filled with a file's content.

Remove the `acme-lib` dependency Although the `acme-lib` crate comes very handy when creating a simple ACME client, a more advanced one may not want to use it. First of all, `acme-lib` does not support all of the ACME specification, some very interesting one are not implemented. Also, it does not store the account public key, which does not allow to revoke certificates. In addition to those two critical points, I would also add `acme-lib` has some troubles with its own dependencies: it uses both `openssl` and `ring`, which is redundant and contribute to inflate the size of the binary. Some of the dependencies also makes an excessive use of logging: even if logging is very useful, in some cases it really is too much and debugging becomes a nightmare. ref #1

Use account objects instead of an email field Defining an account solely by an email address is not the best strategy since the ACME protocol does not require it and also allows for more contacts information.

Change the hook and domains definitions The previous system was too limited when it comes to flexibility using hooks. This limitation came from the false idea that, for a given certificate, all challenges must be validated with the same method. In order to prove that false, domains in a certificate can now make use of any challenge type available. In order to be more flexible, hooks are now given a type and are defined in the same registry (instead of 6). Each one will be called when considered relevant based on its type.

Retry request rejected with a recoverable error Some errors, like the badNonce one, are recoverable. Hence, the client is expected to retry. ACMEd will now re-send the associated request until it succeed or the max retries number is reached. Each retry is preceded by a small waiting time in order to let the server recover in case it was faulty.

  158. - Failure recovery: HTTPS requests rejected by the server that are recoverable, like the badNonce error, are now retried several times before being considered a hard failure.
  159. - The TLS-ALPN-01 challenge is now supported. The proof is a string representation of the acmeIdentifier extension. The self-signed certificate itself has to be built by a hook.

  163. - The format of the `domain` configuration variable has changed and now includes the challenge type.
  164. - The `token` challenge hook variable has been renamed `file_name`.
  165. - The `challenge_hooks`, `post_operation_hooks`, `file_pre_create_hooks`, `file_post_create_hooks`, `file_pre_edit_hooks` and `file_post_edit_hooks` certificate variables has been replaced by `hooks`.
  166. - The logs has been purged from many useless debug and trace entries.
  168. ### Removed
  169. - The DER storage format has been removed.

  183. - It is now possible to define hook groups that can reference either hooks or other hook groups.
  184. - Hooks can be defined when before and after a file is created or edited (`file_pre_create_hooks`, `file_post_create_hooks`, `file_pre_edit_hooks` and `file_post_edit_hooks`).
  185. - It is now possible to send logs either to syslog or stderr using the `--to-syslog` and `--to-stderr` arguments.
  187. ### Changed
  188. - `post_operation_hook` has been renamed `post_operation_hooks`.
  189. - By default, logs are now sent to syslog instead of stderr.
  190. - The process is now daemonized by default. It is possible to still run it in the foreground using the `--foregroung` flag.
