Chain building Symantec timestamping certificate chain on macOS

This app demonstrates X.509 chain building of a Symantec timestamping certificate chain on macOS.

Chain building fails because the timestamping "certificate is blocked."

The certificate chain is:

Level	crt.sh	SHA-1	SHA-256	Subject
root	view	3679ca35668772304d30a5fb873b0fa77bb70d54	2399561127a57125de8cefea610ddf2fa078b5c8067f4e828290bfb860e84b3c	CN=VeriSign Universal Root Certification Authority, OU="(c) 2008 VeriSign, Inc. - For authorized use only", OU=VeriSign Trust Network, O="VeriSign, Inc.", C=US

Running this app will print the following output:

Program ended with exit code: 0

OSStatus -67820 is errSecCertificateRevoked: "The certificate was revoked.".

Status code -2147409652 / 0x8001210C (BlackListedLeaf) applies to the intermediate CA.

Information about distrusting Symantec certificate authorities (HT208860) does not mention anything about this certificate chain.
