Implement `{when_iso_local}` placeholder
This implements the `{when_iso_local}` placeholder. This is like the
`{when_iso}` placeholder but the output is in the current timezone
rather than UTC.
Resolves#2362
All code relating to a caddytls.Config and setting it up from the
Caddyfile is still intact; only the certificate management-related
code was removed into a separate package.
I don't expect this to build in CI successfully; updating dependencies
and vendor is coming next.
I've also removed the ad-hoc, half-baked storage plugins that we need
to finish making first-class Caddy plugins (they were never documented
anyway). The new certmagic package has a much better storage interface,
and we can finally move toward making a new storage plugin type, but
it shouldn't be configurable in the Caddyfile, I think, since it doesn't
make sense for a Caddy instance to use more than one storage config...
We also have the option of eliminating DNS provider plugins and just
shipping all of lego's DNS providers by using a lego package (the
caddytls/setup.go file has a comment describing how) -- but it doubles
Caddy's binary size by 100% from about 19 MB to around 40 MB...!
* tls: Add support for the tls-alpn-01 challenge
Also updates lego/acme to latest on master.
TODO: This implementation of the tls-alpn challenge is not yet solvable
in a distributed Caddy cluster like the http challenge is.
* build: Allow building with the race detector
* tls: Support distributed solving of the TLS-ALPN-01 challenge
* Update vendor and add a todo in MITM checker
* new template action: TLS protocol version
* new template action: use caddytls.GetSupportedProtocolName
Avoids code duplication by reusing existing method to get TLS protocol
version used on connection. Also adds tests
* Adding TLS client cert placeholders
* Use function to get the peer certificate
* Changing SHA1 to SHA256
* Use UTC instead of GMT
* Adding tests
* Adding getters for Protocol and Cipher
- Introduce StrictHostMatching mode for sites that require clientauth
- Error if QUIC is enabled whilst TLS clientauth is configured
(Our QUIC implementation does not yet support TLS clientauth, but
maybe it will in the future - fixes#2095)
- Error if one but not all TLS configs for the same hostname have a
different ClientAuth CA pool
* proof of concept
* Initial implementation with debug code
* Tidy up debug code
* remove unneeded import
* removed extra line
* Move ShouldLog function to rule entry Logger type
* add tests for ShouldLog
* Added tests for log exceptions
* Fix logic
* fix govet fail for test
* Updates requested for code clarity
* Update requested for style
* log: Minor style tweaks to logic of log exceptions
Also add SSL_PROTOCOL and SSL_CIPHER env vars for fastcgi.
* Implement placeholders for ssl_protocol and ssl_cipher
* gofmt
* goimports
* Housekeeping and implement as {tls_protocol} and {tls_cipher}
