Update: ZeroSSL seems to be better than Letsencrypt. I just registered the ZeroSSL command through the following command and then proceeded with the regular
acme.sh --register-account -m <email>
And I have a perfect SSL setup which is PCI-DSS, HIPAA, NIST Compliant
Due to the certificate signature algorithm used by Letsencrypt, my sites weren't getting NIST, HIPAA compliant.
