If for no other reason than Apple requires all outgoing traffic from iOS12+ to be to an HTTPS endpoint - we will need a certificate.

Creating an SSL Certificate

Multisite Signed Certificate from Entrust

Use the $700 unlimited subdomain certificate from Entrust for production environments.

Self Signed Certificate Procedure

Use a SSC for non-production environments

follow and

obrienbiometrics:selfsignedcert$ which openssl
# use "password" as we will be stripping the password
obrienbiometrics:selfsignedcert $ openssl genrsa -des3 -out server.pass.key 2048
Generating RSA private key, 2048 bit long modulus
e is 65537 (0x10001)
Enter pass phrase for server.pass.key:
Verifying - Enter pass phrase for server.pass.key:

obrienbiometrics:selfsignedcert $ openssl rsa -in server.pass.key -out server.key
Enter pass phrase for server.pass.key:
writing RSA key

obrienbiometrics:selfsignedcert $ ls
server.key	server.pass.key

obrienbiometrics:selfsignedcert $ openssl req -nodes -new -key server.key -out server.csr
