ZeroSSL.com CA

1. Register your account with an email address:

acme.sh  --register-account  -m [email protected] --server zerossl

If you already have an account at www.zerossl.com, you can register your acme account with External Account Binding(EAB) credentials.

1. Generate your EAB credentials at: https://app.zerossl.com/developer
2. Register acme account:

acme.sh  --register-account  --server zerossl \
        --eab-kid  xxxxxxxxxxxx  \
        --eab-hmac-key  xxxxxxxxx

2. Done. You can use Zerossl.com with --server zerossl as normal now.

acme.sh --server zerossl  \
     --issue  -d  example.com \
     --dns dns_cf

3. If you don't want to specify --server zerossl every time you issue a cert, you can set zerossl as the default CA:

acme.sh --set-default-ca  --server zerossl

See: https://github.com/acmesh-official/acme.sh/wiki/Server

Then you can issue any cert from zerossl:

acme.sh --issue -d  example.com --dns dns_cf
