∟Verify Certificate Signed by My CA on macOS

This section provides a tutorial example on how to verify certificate signed with my private key and my root CA certificate on macOS using Keychain Access.

After issue Joe's certificate with my root CA, I want to verify details of the certificate.

1. Click "Keychain Access > File > Import Items" menu. The file selection dialog box shows up.

2. Select "joe.pem" to import it into Keychain Access.

3. Open "login" keychain and "Certificates" category. "Joe Doe" certificate is listed there.

4. Double click "Joe Doe" certificate to open it. Details of the certificate show up.

Subject: Joe Doe
Issuer: Herong Yang's CA
Signature: ECDSA Signature with SHA-256 ( 1.2.840.10045.4.3.2 )
Algorithm: RSA Encryption ( 1.2.840.113549.1.1.1 )
Public key: DB 55 6B E6 BA 38 87 56 A9 B5 11 04 09 0C 56 E9 ...

5. Open "login" keychain and "Keys" category. I see Joe's public and private key pair listed there. This is because I generated the CSR on him behalf. I should send the key pair back to him, so he can sign or encrypt documents.
