Mate, you are so great! I tried to solve this freaking problem for about 18h. I added the certificate to my IOS Device, but didn't went to the certificate settings to trust it.
It is so incredible how you could have solved my problem within like 5 minutes.

I definitely left a subscription to such a great YouTuber!
Love you man!

Good video, everything worked perfect to set up my local environment

[atifsamad]

Very nice! what kind of architecture will you propose if we what to implement full-fledged CA ?

[pslamba]

The last step failed for me. Any ideas?

At 2m50s you show emailing the myCA.key to your iOS device. Surely you should keep that one private on the original computer and merely share the .pem file?
Or have I misunderstood what you're proposing here?

On Latest MacOS: You can create RSA keys up to 4096 bits. RSA keys smaller than 2048 bits are no longer supported.

so instead of > openssl genrsa -des3 -out myCA.key 2048
use > openssl genrsa -des3 -out myCA.key 4096
