Chrome Mac Download Certificate

Someday you may need to get the SSL certificate of a website and save it locally.

Posted by Alan Siu May 21, 2015 December 8, 2016 Leave a comment on Permanently add a self-signed certificate to Chrome on a Mac Here's a great tutorial on how to do so. The only thing I had to change was importing the certificate from Keychain Access instead of double-clicking the certificate. Step 5a: DoD certificate installation instructions for Firefox users. NOTE: Firefox will not work on Catalina (10.15.x), or last 4 versions of Mac OS if using the native Apple smartcard ability. Download AllCerts.zip, remember where you save it. Double click the allcerts.zip file (it'll automatically extract into a new folder). Chrome has the following command line switch: — ignore-certificate-errors On Windows 'C:Program Files (x86)GoogleChromeApplicationchrome.exe' -ignore-certificate-errors. Go to the Cross-Certificate Chaining Issue page to download two zip files (i.e.CertificatesPKCS7v4.1u4DoD.zip and unclass-irca1dodrootca2.zip, then use the File Import Certificate option to add the certificates to the 'login' keychain.

For example, you could get an error saying that you can't clone a Git repository due to a self-signed certificate and to resolve this issue you would need to download the SSL certificate and make it trusted by your Git client.
