I'm trying to make an encrypted archive from a pc running linux mint 17.3 MATE. I know one can just use the archive manager (engrampa I think) to make 7z files, and that you can password protect them, but I can't work out whether good strong AES 256 is being used or the weak algorithm typically used for zip files. The "help-->contents" for engrampa warns that the encryption in use isn't the strongest, so I'm not sure if it is hinting that the old zip file algorithm is being used. In 7z on windows I know I could pick which algorithm to use when encrypting a file, in linux mint's archive making dialog I don't see options. How can I check which encryption type is being used, and if it is the weak one have the strong one used instead?
P.S. I checked in software manager and I know that p7zip-full is installed on this system, but I also think it is command line only so trickier to use.
Moderators: feel free to move this to the encryption sub-forum if you want, but I thought as it is more about how encryption is handled within linux mint 17.3 MATE than it is about the underlying principles it might be better in the linux forum.

Back on this site, for a while anyway, been so busy the last year.
My systems:2 laptops, intel i3 processors, windows 8.1 installed on the hard-drive and linux mint 17.3 MATE installed to USB
