Review My Root CA Certificate on macOS

This section provides a tutorial example on how to review my self-signed root CA and make it trusted on macOS using Keychain Access.

From the previous tutorial, I have created a Root CA certificate for myself. Now, let me review it.

1. Open "System" keychain and "Certificates" category in Keychain Access. "Herong Yang's CA" is listed there and marked as untrusted.

2. Double click "Herong Yang's CA" to open it.

3. Click "Trust" to open the section. Select "Always Trust" in "When using this certificate". And close the certificate with your password to save the change.

4. Double click "Herong Yang's CA" to open it again.

5. Click "Details" to review settings in the certificate.

Subject: Herong Yang's CA
Issuer: Herong Yang's CA
Signature: ECDSA Signature with SHA-256 ( 1.2.840.10045.4.3.2 )
Algorithm: Elliptic Curve Public Key ( 1.2.840.10045.2.1 )
Parameters: Elliptic Curve secp521r1 ( 1.3.132.0.35 )
Public Key: 04 01 BD 5B 01 22 38 1B EE C9 2F 79 99 C6 60 46 ...
Usage: Digital Signature, Key Cert Sign
...

Everything looks good! I have a self-signed root CA certificate contains a public key based on the "secp521r1" elliptic curve.
