PGP or S/MIME
« on: January 09, 2020, 04:40:14 pm »
Hi guys,

We began research on a new feature (PGP & S/MIME encryption), requested by many for quite some time now.

This will be a time consuming effort, therefore we'd like to hear your opinion.

What are the pros and cons of each please?
Also - any plans to introduce ActiveSync (in addition to or instead of EWS)?

So I found this summary for everybody to check out from here:
http://www.differencebetween.net/technology/software-technology/difference-between-pgp-and-smime/

Summary:
S/MIME and PGP protocols use different formats for key exchange.
PGP depends upon each user’s key exchange S/MIME uses hierarchically validated certifier for key exchange.
PGP was developed to address the security issues of plain text messages. But S/MIME is designed to secure all kinds of attachments/data files.
Nowadays, S/MIME is known to dominate the secure electronic industry because it is incorporated into many commercial e-mail packages.
S/MIME products are cheaply available than for PGP.

What is the way to get a certificate to be used with s/mime?
I used PGP by now and here you simply create a pair of keys. You share the public part and keep the private part in a safe location.
For s/mime I read about "authorities" where you get the keys from, and that did not seem to be free of charge. Correct me, if I am wrong.
Maybe the s/mime certificates from authorities provide more safety, who the author of a signed mail is. Anyway just using own PGP certificates seems to be more convenient for me.
In conclusion I would vote for PGP.
