Is zip compression with a password in standard install MATE 18.04 & coming 18.10, AES-256? I’m low tech and want to avoid encryption keys to store things like old tax returns in the cloud. Just read some zip with passwords are not AES-256. Maybe it was an old article. If I zip a Libre document, spreadsheet or adobe file with a password in standard MATE 18.04, is it AES-256 and secure in the cloud. Don’t want to pay Spideroak $40 per year to encrypt 0.2 gig of personal info.
@Jim4444 7-Zip is what you need. It has password protection with strong AES-256 encryption. That being said, I can't remember if I installed it, or if it shipped with UM18.04.
Either way, just open mate-terminal and enter the following command
sudo apt install p7zip-full
Then install p7zip-full if it's not already installed.
From there just right click on the file or folder that you wish to encrypt, select compress, then select 7z, expand Other Options and entering your encryption password. See the screenshot below for further explanation.

Thanks. Since I always have trouble with the terminal I went to a document to compress and one of the options is .7z which matches 7zip. Now I just need to recompress my files.
Great, if that solves your inquiry, please mark the post as solved so it may better help others later on. Happy compressing Jim
