I keep a personal journal which I store in a hidden folder to keep it private (ie away from non-advanced linux users) but I would like to be able to actually encrypt them so I'm the only one to have access to them in future.<p>What do you usually use for such purpose ? As I mentioned in the paragraph above, I'm on Linux.<p>Thanks in advance !
I use Cryptomator. <a href="https://cryptomator.org" rel="nofollow">https://cryptomator.org</a><p>I'm not sure of the program's technical specs, but it is multi-platform, available on mobile, and is easy to use. I am able to have a shared set of secured documents with various non-technical family members. I'm not overly worried about the Goverment having my files and I <i>feel</i> it is good enough to keep Dropbox and other hypothetical 3rd parties from my most sensitive documents.
I encrypt lots of things. I use the following: To encrypt directories cryptsetup and encfs on linux, dmg on mac, geli on freebsd and git-crypt with private bitbucket repos for docs that I'd like to have a history log (commits).<p>I think that in your case, you could take a look at git-crypt, but make sure you understand <i>what</i> is encrypted and <i>what</i> is not. Also make sure you don't <i>push</i> before <i>git-crypt lock</i>. A bash prompt changing colours might be handy.
On Linux, you can encrypt your drives using LUKS and cryptsetup. If you want to encrypt single files, you can use gpg2 (with a password, or with a keyfile)
I personally use DiskCryptor, but I am not super up-to-date on the best programs for encryption/decryption.<p>DiskCryptor does the job for me. Easy to use, open source.
