This will unblock pre-issuance linting support by updating the
`github.com/cloudflare/cfssl` dependency to the `1.3.4` tag which
notably includes the zlint integration developed in
cloudflare/cfssl#1015
Notably this brings in:
* A mild perf. boost from an updated transitive zcrypto dep and a reworked util func.
* A new KeyUsage lint for ECDSA keys.
* Updated gTLD data.
* A required `LintStatus` deserialization fix that will unblock a CFSSL update.
The `TestIgnoredLint` unit test is updated to no longer expect a warning from the
` w_serial_number_low_entropy` lint. This lint was removed in the upstream project.
Also excises the existing bad padding metrics code, adds a special error for when we encounter badly padded keys, and adds a test for the new special error.
Fixes#4070 and fixes#3964.
Because the package versions in go.mod match what we use in Godeps.json,
there are no substantive code diffs. However, there are some tiny
differences resulting from how go mod vendors things differently than
godep:
go mod does not preserve executable permissions on shell scripts
Some packages have import lines like:
package ocsp // import "golang.org/x/crypto/ocsp"
godep used to remove the comment from these lines, but go mod vendor does not.
This introduces several indirect dependencies that we didn't have
before. This is because godep used to operate at a package level, but
go mod operates at a module (~= repository) level. So if we used a
given repository, but didn't use all of its packages, we wouldn't
previously care about the transitive dependencies of the packages we
weren't using. However, in the go mod world, once we care about the
repository, we care about all of that repository's transitive
dependencies. AFAICT this doesn't affect vendoring.
Fixes#4116
