I appreciate the negatives of self-executable files but the reality is many companies do allow them. Once the file/s have been extracted the virus scanners check the contents aren’t malicious.
Okay, some email systems don’t allow .exe them but there’s nothing to stop you uploading it to a shared cloud service like Google Drive. Or you can change the extension and ask the recipient to change it once downloaded.
There are increasing numbers of fully encrypted cloud services now which make file-sharing even easier. For users of these they make the AxCrypt software redundant. People who want to share files on a non-encrypted cloud service have to either upload the file encrypted with another piece of software or upload it unencrypted.
It’s all well and good saying that people can download a standalone piece of software to decrypt files shared with them but that is another interruption to their workflow.
There’s no real difference between PGP and AxCrypt 2. The user interface is very friendly and there’s no real difference in underlying concept. On the plus side PGP does allow symmetric encryption and a number of different algorithms. PGP has been around for nearly 30 years and has been tried and tested.
Your comments about the ongoing development of PGP aren’t really applicable to the average (non-commercial) user because the excellent GNUPG is continually updated for Windows, Linux, Mac, Android, VMS and RISC OS. It was last updated in August 2016.
The original PGP is indeed owned by Symantec but the open-source variant (GNUPG) is the most commonly used and receives significant funding.
I really wish you’d take peoples comments on-board and re-introduce the removed features because there are a lot of people on this forum who seem prepared to pay (historically you were freeware) if you were to give them what they wanted.
