SSL.com CA

SSL.com is providing free 90 days certs.

The cert can only contain one domain and its www sub domain.

No wildcard certs.

acme.sh  --server ssl.com   --issue  -d example.com  -d www.example.com ........

Please register a free account at www.ssl.com, and then get your EAB Credentials:

Next:

1. Register an account:

acme.sh  --register-account  --server ssl.com  \
              -m  my@example.com   \
             --eab-kid  xxxxxx     --eab-hmac-key  xxxxxxxx

And also register an ECDSA account:

acme.sh  --register-account   --server ssl.com \
          -m  my@example.com   \
          --eab-kid  xxxxxx     --eab-hmac-key  xxxxxxxx   --ecc

2. Then you can issue certs with --server parameter:

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

Or, issue an ECDSA cert:

acme.sh --issue  -d example.com  --dns dns_cf    --server  ssl.com  -k  ec-256
