2022-03-25go.mod: Upgrade CertMagic to v0.16.0Matthew Holt
Includes several breaking changes; code base updated accordingly. - Added lots of context arguments - Use fs.ErrNotExist - Rename ACMEManager -> ACMEIssuer; CertificateManager -> Manager
2022-03-08caddytls: dns_challenge_override_domain for challenge delegation (#4596)Ran Chen
* Add a override_domain option to allow DNS chanllenge delegation CNAME can be used to delegate answering the chanllenge to another DNS zone. One usage is to reduce the exposure of the DNS credential [1]. Based on the discussion in caddy/certmagic#160, we are adding an option to allow the user explicitly specify the domain to delegate, instead of following the CNAME chain. This needs caddy/certmagic#160. * rename override_domain to dns_challenge_override_domain * Update CertMagic; fix spelling Co-authored-by: Matthew Holt <mholt@users.noreply.github.com>
2022-02-17caddytls: Support external certificate Managers (like Tailscale) (#4541)Matt Holt
Huge thank-you to Tailscale (https://tailscale.com) for making this change possible! This is a great feature for Caddy and Tailscale is a great fit for a standard implementation. * caddytls: GetCertificate modules; Tailscale * Caddyfile support for get_certificate Also fix AP provisioning in case of empty subject list (persist loaded module on struct, much like Issuers, to surive reprovisioning). And implement start of HTTP cert getter, still WIP. * Update modules/caddytls/automation.go Co-authored-by: Francis Lavoie <lavofr@gmail.com> * Use tsclient package, check status for name * Implement HTTP cert getter And use reuse CertMagic's PEM functions for private keys. * Remove cache option from Tailscale getter Tailscale does its own caching and we don't need the added complexity... for now, at least. * Several updates - Option to disable cert automation in auto HTTPS - Support multiple cert managers - Remove cache feature from cert manager modules - Minor improvements to auto HTTPS logging * Run go mod tidy * Try to get certificates from Tailscale implicitly Only for domains ending in .ts.net. I think this is really cool! Co-authored-by: Francis Lavoie <lavofr@gmail.com>

2021-04-21caddytls: Add `load_storage` module (#4055)Francis Lavoie
An idea that came up in https://caddy.community/t/save-internally-issued-wildcard-certificate-in-consul/11740, this a simple module that might be useful for anyone who uses storage modules that aren't filesystem, to let them load certs/keys externally issued for use by Caddy. Bit goofy, since we need to fetch the certmagic.Storage during provisioning, it needs a wrapping struct instead of just being an array like `load_files`. Future work might involve adding Caddyfile support via a subdirective of the `tls` directive maybe?
2021-04-12caddytls: Disable OCSP stapling for manual certs (#4064)Matthew Holt
2021-04-12caddytls: Configurable storage clean intervalMatthew Holt
Can drastically reduce costs on storage backends where scans are expensive. Also reduced default interval to 24h. See https://github.com/silinternational/certmagic-storage-dynamodb/issues/18

2021-02-10caddytls: Save email with account if not already specifiedMatthew Holt
I'm pretty sure this fixes a bug when the default email is used...
2021-02-02acmeserver: Support custom CAs from CaddyfileMatthew Holt
The HTTP Caddyfile adapter can now configure the PKI app, and the acme_server directive can now be used to specify a custom CA used for issuing certificates. More customization options can follow later as needed.
2021-02-02httpcaddyfile: Fix default issuers when email providedMatthew Holt
If `tls <email>` is used, we should apply that to all applicable default issuers, not drop them. This refactoring applies implicit ACME issuer settings from the tls directive to all default ACME issuers, like ZeroSSL. We also consolidate some annoying logic and improve config validity checks.

2021-01-27admin: Identity management, remote admin, config loaders (#3994)Matt Holt
This commits dds 3 separate, but very related features: 1. Automated server identity management How do you know you're connecting to the server you think you are? How do you know the server connecting to you is the server instance you think it is? Mutually-authenticated TLS (mTLS) answers both of these questions. Using TLS to authenticate requires a public/private key pair (and the peer must trust the certificate you present to it). Fortunately, Caddy is really good at managing certificates by now. We tap into that power to make it possible for Caddy to obtain and renew its own identity credentials, or in other words, a certificate that can be used for both server verification when clients connect to it, and client verification when it connects to other servers. Its associated private key is essentially its identity, and TLS takes care of possession proofs. This configuration is simply a list of identifiers and an optional list of custom certificate issuers. Identifiers are things like IP addresses or DNS names that can be used to access the Caddy instance. The default issuers are ZeroSSL and Let's Encrypt, but these are public CAs, so they won't issue certs for private identifiers. Caddy will simply manage credentials for these, which other parts of Caddy can use, for example: remote administration or dynamic config loading (described below). 2. Remote administration over secure connection This feature adds generic remote admin functionality that is safe to expose on a public interface. - The "remote" (or "secure") endpoint is optional. It does not affect the standard/local/plaintext endpoint. - It's the same as the [API endpoint on localhost:2019](https://caddyserver.com/docs/api), but over TLS. - TLS cannot be disabled on this endpoint. - TLS mutual auth is required, and cannot be disabled. - The server's certificate _must_ be obtained and renewed via automated means, such as ACME. It cannot be manually loaded. - The TLS server takes care of verifying the client. - The admin handler takes care of application-layer permissions (methods and paths that each client is allowed to use).\ - Sensible defaults are still WIP. - Config fields subject to change/renaming. 3. Dyanmic config loading at startup Since this feature was planned in tandem with remote admin, and depends on its changes, I am combining them into one PR. Dynamic config loading is where you tell Caddy how to load its config, and then it loads and runs that. First, it will load the config you give it (and persist that so it can be optionally resumed later). Then, it will try pulling its _actual_ config using the module you've specified (dynamically loaded configs are _not_ persisted to storage, since resuming them doesn't make sense). This PR comes with a standard config loader module called `caddy.config_loaders.http`. Caddyfile config for all of this can probably be added later. COMMITS: * admin: Secure socket for remote management Functional, but still WIP. Optional secure socket for the admin endpoint is designed for remote management, i.e. to be exposed on a public port. It enforces TLS mutual authentication which cannot be disabled. The default port for this is :2021. The server certificate cannot be specified manually, it MUST be obtained from a certificate issuer (i.e. ACME). More polish and sensible defaults are still in development. Also cleaned up and consolidated the code related to quitting the process. * Happy lint * Implement dynamic config loading; HTTP config loader module This allows Caddy to load a dynamic config when it starts. Dynamically-loaded configs are intentionally not persisted to storage. Includes an implementation of the standard config loader, HTTPLoader. Can be used to download configs over HTTP(S). * Refactor and cleanup; prevent recursive config pulls Identity management is now separated from remote administration. There is no need to enable remote administration if all you want is identity management, but you will need to configure identity management if you want remote administration. * Fix lint warnings * Rename identities->identifiers for consistency
2021-01-07caddytls: Configurable OCSP stapling; global option (closes #3714)Matthew Holt
Allows user to disable OCSP stapling (including support in the Caddyfile via the ocsp_stapling global option) or overriding responder URLs. Useful in environments where responders are not reachable due to firewalls.
2021-01-07httpcaddyfile: Support repeated use of cert_issuer global optionMatthew Holt
This changes the signature of UnmarshalGlobalFunc but this is probably OK since it's only used by this repo as far as we know. We need this change in order to "remember" the previous value in case a global option appears more than once, which is now a possibility with the cert_issuer option since Caddy now supports multiple issuers in the order defined by the user. Bonus: the issuer subdirective of tls now supports one-liner for "acme" when all you need to set is the directory: issuer acme <dir>
2021-01-05caddyfile: Refactor unmarshaling of module tokensMatthew Holt
Eliminates a fair amount of repeated code
2020-12-15caddytls: Improve alt chain preference settingsMatthew Holt
This allows for finer-grained control when choosing alternate chains than simply the previous/Certbot-esque behavior of "choose first chain that contains an issuer's common name." This update allows you to sort by length (if optimizing for efficiency on the wire) and also to select the chain with a specific root CommonName.

2020-10-22httpcaddyfile: Improve AP logic with OnDemandMatthew Holt
We have users that have site blocks like *.*.tld with on-demand TLS enabled. While *.*.tld does not qualify for a publicly-trusted cert due to its wildcards, On-Demand TLS does not actually obtain a cert with those wildcards, since it uses the actual hostname on the handshake. This improves on that logic, but I am still not 100% satisfied with the result since I think we need to also check if another site block is more specific, like foo.example.tld, which might not have on-demand TLS enabled, and make sure an automation policy gets created before the more general policy with on-demand...

2020-08-11caddytls: Add support for ZeroSSL; add Caddyfile support for issuers (#3633)Matt Holt
* caddytls: Add support for ZeroSSL; add Caddyfile support for issuers Configuring issuers explicitly in a Caddyfile is not easily compatible with existing ACME-specific parameters such as email or acme_ca which infer the kind of issuer it creates (this is complicated now because the ZeroSSL issuer wraps the ACME issuer)... oh well, we can revisit that later if we need to. New Caddyfile global option: { cert_issuer <name> ... } Or, alternatively, as a tls subdirective: tls { issuer <name> ... } For example, to use ZeroSSL with an API key: { cert_issuser zerossl API_KEY } For now, that still uses ZeroSSL's ACME endpoint; it fetches EAB credentials for you. You can also provide the EAB credentials directly just like any other ACME endpoint: { cert_issuer acme { eab KEY_ID MAC_KEY } } All these examples use the new global option (or tls subdirective). You can still use traditional/existing options with ZeroSSL, since it's just another ACME endpoint: { acme_ca https://acme.zerossl.com/v2/DV90 acme_eab KEY_ID MAC_KEY } That's all there is to it. You just can't mix-and-match acme_* options with cert_issuer, because it becomes confusing/ambiguous/complicated to merge the settings. * Fix broken test This test was asserting buggy behavior, oops - glad this branch both discovers and fixes the bug at the same time! * Fix broken test (post-merge) * Update modules/caddytls/acmeissuer.go Fix godoc comment Co-authored-by: Francis Lavoie <lavofr@gmail.com> * Add support for ZeroSSL's EAB-by-email endpoint Also transform the ACMEIssuer into ZeroSSLIssuer implicitly if set to the ZeroSSL endpoint without EAB (the ZeroSSLIssuer is needed to generate EAB if not already provided); this is now possible with either an API key or an email address. * go.mod: Use latest certmagic, acmez, and x/net * Wrap underlying logic rather than repeating it Oops, duh * Form-encode email info into request body for EAB endpoint Co-authored-by: Francis Lavoie <lavofr@gmail.com>
