S.S.E. File Encryptor for PC on Linux

Post by InChrist » Fri Apr 20, 2018 7:14 pm

I use this on Android. Can you recommend it for Linux Mint?
https://paranoiaworks.mobi/ssefepc/
Is it secure or could it damage my system?
4.8.0-53-generic x86_64 (64 bit gcc: 5.4.0)
Cinnamon 3.4.6 (Gtk 3.18.9-1ubuntu3.3) dm: lightdm
Linux Mint 18.2 Sonya
I have only updated up to level 2.

I downloaded SSEFilePC.zip from https://paranoiaworks.mobi/download/, extracted it, extracted ssefencgui.jar, but I do not know which file to use to run the software.
The USAGE.txt says: Java 6 or later is needed (http://java.com/download)
I do not know if this is on my system.
I would be happy to receive competent clear help.

I get an 'Untrusted' warning from the site you have pointed to, not a good start really. Is the application open-source? Not just free, can you actually download the source code. This is particularly important in cryptographic circles, where everyone is invited to take a crack at the output files and at the source code.

Linux has perfectly good encryption methods without adding anything...
o Cryptsetup 'plain' for RAID arrays.
o Cryptsetup 'luks' for partitions and removable stores.
o Cryptfs for Ubuntu home folders.
o 7z + password for single files.

Thank you, Mute Ant.
I need it for my linux system and then send the encrypted or password protected folder or file to an android phone, a windows computer, an iphone and all other directions ... and they all should be able to open it with the right password or also easily secure files or folders themselves. Which software, apps are best? I found that I get an error: Can not extract file, when I make a zip- or 7z-file with password on my android phone and try to extract it in Nemo on my Linux laptop.

"Can not extract file" is a programming wobbly I have seen in MATE. It is supposed to prompt for a password. It would be nice if it told you that and suggested you install the helper-program package p7zip-full which can decode encrypted 7z files.

sudo apt-get install p7zip-full ...should fix your Mint so it can make and open encrypted 7z files.

Assuming the 7z file was assembled correctly, you can try a different archive program. I know of ark, engrampa, file-roller and xarchiver. I stick with file-roller because it can make ISO9660 files.

Legacy zip-with-a-password was cracked many years ago. Zip can't hide your data from anyone who really wants to look at it, even if they don't have a password.
