# Summary:
Safari, Chrome and cURL cannot connect to certain websites because of an invalid SSL certificate chain in the CRL and OCSP caches.

# Steps to Reproduce:

1. Open a URL to site where the certificate chain is invalid. On my mac, Safari and cURL cannot connect to https://files.pythonhosted.org

$ /usr/bin/curl --remote-time --location --user-agent Homebrew/1.1.7 (Macintosh; Intel macOS 10.12.2) curl/7.51.0 --fail https://files.pythonhosted.org/packages/05/25/7b5484aca5d46915493f1fd4ecb63c38c333bd32aa9ad6e19da8d08895ae/docutils-0.13.1.tar.gz -C 0 -o /Users/king/Library/Caches/Homebrew/mpv--docutils-0.13.1.tar.gz.incomplete

curl: (60) SSL certificate problem: Invalid certificate chain
More details here: https://curl.haxx.se/docs/sslcerts.html

curl performs SSL certificate verification by default, using a "bundle"
 of Certificate Authority (CA) public keys (CA certs). If the default
 bundle file isn't adequate, you can specify an alternate file
 using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
 the bundle, the certificate verification probably failed due to a
 problem with the certificate (it might be expired, or the name might
 not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
 the -k (or --insecure) option.

# Expected Results:
Safari and cURL should be able to connect to the website using the system certificates.

# Actual Results:
curl: (60) SSL certificate problem: Invalid certificate chain
Safari: Can’t connect to website

# Workaround:
Delete the CRL and OCSP caches:

OS X (through 10.11)

To delete both OCSP and CRL cache, in a terminal, enter the following command:
sudo rm /var/db/crls/*cache?.db

OS X 10.12 Sierra

To delete both OCSP and CRL cache in OS X 10.12, open a terminal and run the following command:
sqlite3 ~/Library/Keychains/*/ocspcache.sqlite3 'DELETE FROM ocsp;'

# Solution

Please add a menu option to the Keychain.app (and a command line option) for the user to easily delete the CRL and OCSP certificate caches, so the user does not have to resort to manually deleting files in the /var/db/crls and modifying the local keychain using sqlite3.

Thank you.
