In our environment we use DNS manual mode and take the TXT record
output of acme.sh and process it with Ansible to install the records
(then we call renew later when the records have been pushed to the DNS
servers by a whole bunch of other bits).
One problem is that after getting/showing the TXT records, acme.sh
always returns 1. This makes it difficult to tell if there is
actually an error condition.
Since we have set the manual-mode flag, not installing the DNS records
is an expected correct result. This returns a separate error code for
this situation (3), which can be distinguished in automation.
Some CAs auto-validate orders based on account-level rules and do not
require a challenge at all. Sectigo introduced a non-standard challenges
named 'sectigo-dns-01', presumably to work around this issue in certbot.
This also works for non-wildcard domains in acme.sh, but wildcard domains
are rejected because acme.sh hard-codes 'dns-01' as the only allowed
challenge for wildcard domains, which is not offered by Sectigo.
This change simply moves the '"status":"valid"' check up a bit and ignores
challenge type mismatches or missing tokens if no challenge is needed anyway.
When performing renewals acme.sh checks key length values to determine
if a new key should be created with createDomainKey(). However, older
acme.sh stored key length as an empty value if the default of 2048 was
desired. Now it is explicit and the explict check of 2048 against "" is
causing createDomainKey() to always be called with fails without
--force.
Fix this by converting the keylength value to 2048 if an empty string is
returned from the config file. acme.sh will then write out 2048 updating
old keys and configs to the explicit version.
