Will there be a conflict using S/MIME alongside OpenPGP?
Which of our tools is giving you problems?
While waiting for the Catalina version to come out, a friend and I explored and found how to use S/MIME certificates which has the advantage that you can teach it to iOS devices. As a result, I have not installed the latest GPG Tools. I have the GPG Keychain installed but not the email piece.
Now, a friend has emailed me with an email encrypted with my old GPG (PGP) key so I'm wondering if I can install the email piece of GPG Tools and be able to keep the capabilities I have using S/MIME certificates (encrypt, sign, decrypt, and verify signatures) along with using GPG.
Thank you for your help,
Perry

Hi Perry,
thanks for asking about using S/MIME and OpenPGP side by side.
This security stackexchange thread covers the questions how OpenPGP and S/MIME differ:
https://security.stackexchange.com/questions/7874/how-does-pgp-diff...
Please keep in mind that S/MIME does not have any MDC (Modification Detection Code) and is thus still vulnerable to Efail.
You can simply use the top right indicator to switch between S/MIME and OpenPGP. Make sure to use the nightly build as that includes a fix which is not yet included in 2019.2 and concerns the indicator.
All the best,
Steve

Hi Steve,
Just now got around to trying GPG and it is working fine.
The links you provided gave me and my friend a couple days of fun. He is an ex-crypto driver writer for AIX (IBM's version of Unix).
Good luck and take care
Perry
