I have a bit of data that has to be encrypted and stored into a file so that it can be moved across file systems and possibly OSes. Disk encryption like dm-crypt and a loop device isn’t appropriate as it may not exist on another OS.
It’s been a very long time since I needed this sort of software. More than a decade ago I used TrueCrypt. I know that VeraCrypt is the current re-incarnationn of the project. Is that still the go-to software for this sort of application? Is there something else that’s popular these days?
Veracrypt
Yes highly recommend Veracrypt.
Seconded. Veracrypt is great with lots of flexibility in how you can do the encryption, good documentation, support for passwords and keyfiles, the ability to mount encrypted files as drives, etc… Great software.
Zip the file(s), then GPG symmetric encryption/decryption with AES. Nothing fancy.
I use gocryptfs, i like having both CLI for scripts and its got GUI built into KDE Plasma’s Vault feature
If you’re comfortable on the command line, you can use good old GnuPG to encrypt a file. There are binaries available for Windows too.
I’d recommend encrypted archives. Like using 7z/7zip to encrypt files.
I personally use Cryptomator, which does on-the-fly data encryption/decryption, allowing you to mount the encrypted data as a “drive” which from the user’s perspective looks like any other data drive.
I like securefs and use it with sirikali. It doesn’t use a single container but encrypts the files and names.
